INTRODUCTION
About This Machine
Foreword
"The screw cutting engine lathe is the oldest and
most important of machine tools and from it all
other machine tools have been developed. It was
the lathe that made possible the building of the
steamboat, the locomotive, the electric motor, the
automobile and all kinds of machinery used in
industry. Without the lathe our great industrial
progress of the last century would have been
impossible." —How To Run a Lathe, 15th
Edition, South Bend Lathe.
The lathe represented in this manual is a
modern day version of the screw cutting lathes
that trace their roots back to the 1700's, which
were themselves technological improvements of
the bow lathe that can be traced back thousands
of years to the ancient Egyptians.
Now, almost 300 years later, these modern
"screw cutting" lathes are not just a piece of
refined machinery, but a culmination of human
ingenuity and knowledge embodied into the
design and synergy of thousands of interworking
parts—some of which represent the life's work
and dreams of many inventors, mechanical
engineers, and world-class machinists—including
the likes of Leonardo da Vinci, Henry Maudsley,
and the founders of South Bend Lathe, John and
Miles O'Brien.
And now the torch is passed to you—to take
the oldest and most important type of machine
tool—and carry on the tradition. As the operator
of a South Bend Lathe, you now join the ranks
of some very famous and important customers,
such as Henry Ford, who used the machines he
purchased to help him change the world.
Features
As the name implies, these lathes feature EVS
(Electronic Variable Speed) spindle control
to "dial in" the perfect cutting speed for the
operation. One of four spindle speed ranges is
selected with the speed range lever, then the
exact speed within that range is chosen with the
spindle speed dial. The current spindle speed
is displayed with the digital tachometer on the
control panel.
The beds of these lathes are constructed with
Meehanite castings that are hardened and
precision-ground in the traditional three V-way
prismatic design—long used on South Bend
Lathes for its accuracy, durability, and rigidity.
The headstocks feature quick-change gear levers
and the carriages include an adjustable clutch
that disables automatic carriage feed when it
contacts the included feed stop or in the event of
a crash.
To further ensure a high degree of accuracy,
these lathes are equipped with high-quality
spindle bearings and a Fagor 2-Axis DRO. The
spindles are D1-8 camlock with an MT#7 taper
and 3.15" bore. The tailstocks have an MT#5
taper and 6.5" of quill travel.
The headstocks are equipped with a pressurized
oiling system that pre-lubricates the bearings
and gears before the spindle starts. This
guarantees that the headstocks are properly
lubricated in all start-up conditions, including
high-load/low-speed operations.
Finally, these EVS toolroom lathes are packed
with a premium Yaskawa Inverter, Allen-
Bradley contactors, thermal relays, and fuse
system. Also included are a complete coolant
system, an easy-to-clean chip drawer, one-shot
way lubrication system, ball bearing steady
rest and brass-tipped follow rest, adjustable
work lamp, foot brake, and automatic feeding
capabilities for both the X- and Y-axis.
Capabilities
These EVS Toolroom Lathes are built for daily
use in a busy industrial setting. Loaded with
many nice features and high-precision parts,
these lathes excel at making fine tools, dies,
thread gauges, jigs, and precision test gauges—
however, they are by no means delicate. Thick
castings, heavy weight, and quality construction
throughout provide the necessary brawn for
demanding production and manufacturing tasks.

Safety Foot Brake
This lathe is equipped with a foot brake (see
Figure 9) to quickly stop the spindle instead of
allowing it to coast to a stop on its own. Pressing
the foot brake while the spindle is ON also cuts
power to the motor.
After the foot brake is used, the spindle lever
must be returned to the OFF (middle) position to
reset the spindle switches before spindle rotation
can be re-started.

SAFETY
Understanding Risks of Machinery
Operating all machinery and machining equipment can be dangerous or relatively safe depending
on how it is installed and maintained, and the operator's experience, common sense, risk awareness,
working conditions, and use of personal protective equipment (safety glasses, respirators, etc.).
The owner of this machinery or equipment is ultimately responsible for its safe use. This
responsibility includes proper installation in a safe environment, personnel training and usage
authorization, regular inspection and maintenance, manual availability and comprehension,
application of safety devices, integrity of cutting tools or accessories, and the usage of approved
personal protective equipment by all operators and bystanders.
The manufacturer of this machinery or equipment will not be held liable for injury or property
damage from negligence, improper training, machine modifications, or misuse. Failure to read,
understand, and follow the manual and safety labels may result in serious personal injury, including
amputation, broken bones, electrocution, or death.
The signals used in this manual to identify hazard levels are defined as follows:
Death or catastrophic
harm WILL occur.

-18-
For Machines Mfg. Since 3/11
Turn-Nado® EVS Lathes SAFETY
Entanglement: Loose clothing, gloves, neckties,
jewelry or long hair may get caught in
moving parts, causing entanglement,
amputation, crushing, or strangulation.
Reduce this risk by removing/securing
these items so they cannot contact moving
parts.
Mental Alertness: Operating this item with
reduced mental alertness increases the
risk of accidental injury. Do not let a
temporary influence or distraction lead to a
permanent disability! Never operate when
under the influence of drugs/alcohol, when
tired, or otherwise distracted.
Safe Environment: Operating electrically
powered equipment in a wet environment
may result in electrocution; operating near
highly flammable materials may result in a
fire or explosion. Only operate this item in
a dry location that is free from flammable
materials.
Electrical Connection: With electically powered
equipment, improper connections to the
power source may result in electrocution
or fire. Always adhere to all electrical
requirements and applicable codes when
connecting to the power source. Have all
work inspected by a qualified electrician to
minimize risk.
Disconnect Power: Adjusting or servicing
electrically powered equipment while it
is connected to the power source greatly
increases the risk of injury from accidental
startup. Always disconnect power
BEFORE any service or adjustments,
including changing blades or other tooling.
Secure Workpiece/Tooling: Loose workpieces,
cutting tools, or rotating spindles can
become dangerous projectiles if not
secured or if they hit another object during
operation. Reduce the risk of this hazard
by verifying that all fastening devices are
properly secured and items attached to
spindles have enough clearance to safely
rotate.
Chuck Keys or Adjusting Tools: Tools used to
adjust spindles, chucks, or any moving/
rotating parts will become dangerous
projectiles if left in place when the machine
is started. Reduce this risk by developing
the habit of always removing these tools
immediately after using them.
Work Area: Clutter and dark shadows increase
the risks of accidental injury. Only operate
this item in a clean, non-glaring, and well-
lighted work area.
Properly Functioning Equipment: Poorly
maintained, damaged, or malfunctioning
equipment has higher risks of causing
serious personal injury compared to
those that are properly maintained.
To reduce this risk, always maintain
this item to the highest standards and
promptly repair/service a damaged or
malfunctioning component. Always follow
the maintenance instructions included in

Unattended Operation: Electrically powered
equipment that is left unattended while
running cannot be controlled and is
dangerous to bystanders. Always turn the
power OFF before walking away.
Health Hazards: Certain cutting fluids and
lubricants, or dust/smoke created when
cutting, may contain chemicals known to
the State of California to cause cancer,
respiratory problems, birth defects,
or other reproductive harm. Minimize
exposure to these chemicals by wearing
approved personal protective equipment
and operating in a well ventilated area.
Difficult Operations: Attempting difficult
operations with which you are unfamiliar
increases the risk of injury. If you

SAFETY
Additional Metal Lathe Safety
Clearing Chips. Metal chips can easily cut bare
skin—even through a piece of cloth. Avoid
clearing chips by hand or with a rag.Use a
brush or vacuum to clear metal chips.
Stopping Spindle by Hand. Stopping the spindle
by putting your hand on the workpiece
or chuck creates an extreme risk of
entanglement, impact, crushing, friction, or
cutting hazards. Never attempt to slow or
stop the lathe spindle with your hand. Allow
the spindle to come to a stop on its own or
use the brake.
Crashes. Aggressively driving the cutting tool
or other lathe components into the chuck
may cause an explosion of metal fragments,
which can result in severe impact injuries
and major damage to the lathe. Reduce this
risk by releasing automatic feeds after use,
not leaving lathe unattended, and checking
clearances before starting the lathe.
Make sure no part of the tool, tool holder,
compound rest, cross slide, or carriage will
contact the chuck during operation.
Coolant Safety. Coolant is a very poisonous
biohazard that can cause personal injury
from skin contact alone. Incorrectly
positioned coolant nozzles can splash on
the operator or the floor, resulting in an
exposure or slipping hazard. To decrease
your risk, change coolant regularly and
position the nozzle where it will not splash
or end up on the floor.
Tool Selection. Cutting with an incorrect or
dull tool increases the risk of accidental
injury due to the extra force required for
the operation, which increases the risk of
breaking or dislodging components that
can cause small shards of metal to become
dangerous projectiles. Always select the
right cutter for the job and make sure it is
sharp. A correct, sharp tool decreases strain
and provides a better finish.
Speed Rates. Operating the lathe at the wrong
speed can cause nearby parts to break or the
workpiece to come loose, which will result in
dangerous projectiles that could cause severe
impact injuries. Large or non-concentric
workpieces must be turned at slow speeds.
Always use the appropriate feed and speed
rates.
Chuck Key Safety. A chuck key left in the chuck
can become a deadly projectile when the
spindle is started. Always remove the chuck
key after using it. Develop a habit of not
taking your hand off of a chuck key unless it
is away from the machine.
Safe Clearances. Workpieces that crash into
other components on the lathe may throw
dangerous projectiles in all directions,
leading to impact injury and damaged
equipment. Before starting the spindle,
make sure the workpiece has adequate
clearance by hand-rotating it through its
entire range of motion. Also, check the tool
and tool post clearance, chuck clearance, and
saddle clearance.
Long Stock Safety. Long stock can whip violently
if not properly supported, causing serious
impact injury and damage to the lathe.
Reduce this risk by supporting any stock
that extends from the chuck/headstock more
than three times its own diameter. Always
turn long stock at slow speeds.
Securing Workpiece. An improperly secured
workpiece can fly off the lathe spindle with
deadly force, which can result in a severe
impact injury. Make sure the workpiece is
properly secured in the chuck or faceplate
before starting the lathe.
Chucks. Chucks are very heavy and difficult to
grasp, which can lead to crushed fingers or
hands if mishandled. Get assistance when
handling chucks to reduce this risk. Protect
your hands and the precision-ground ways
by using a chuck cradle or piece of plywood
over the ways of the lathe when servicing
chucks. Use lifting devices when necessary.

For Machines Mfg. Since 3/11
Turn-Nado® EVS Lathes SAFETY
Additional Chuck Safety
Entanglement. Entanglement with a rotating
chuck can lead to death, amputation, broken
bones, or other serious injury. Never attempt
to slow or stop the lathe chuck by hand,
and always roll up long sleeves, tie back
long hair, and remove any jewelry or loose
apparel BEFORE operating.
Chuck Speed Rating. Excessive spindle speeds
greatly increase the risk of the workpiece or
chuck being thrown from the machine with
deadly force. Never use spindle speeds faster
than the chuck RPM rating or the safe limits
of your workpiece.
Using Correct Equipment. Many workpieces can
only be safely turned in a lathe if additional
support equipment, such as a tailstock or
steady rest, is used. If the operation is too
hazardous to be completed with the lathe or
existing equipment, the operator must have
enough experience to know when to use a
different machine or find a safer way.
Trained Operators Only. Using a chuck
incorrectly can result in workpieces coming
loose at high speeds and striking the
operator or bystanders with deadly force.
To reduce the risk of this hazard, read
and understand this document and seek
additional training from an experienced
chuck user before using a chuck.
Chuck Capacity. Avoid exceeding the capacity
of the chuck by clamping an oversized
workpiece. If the workpiece is too large to
safely clamp with the chuck, use a faceplate
or a larger chuck if possible. Otherwise, the
workpiece could be thrown from the lathe
during operation, resulting in serious impact
injury or death.
Clamping Force. Inadequate clamping force
can lead to the workpiece being thrown
from the chuck and striking the operator
or bystanders. Maximum clamping force
is achieved when the chuck is properly
maintained and lubricated, all jaws are
fully engaged with the workpiece, and the
maximum chuck clamping diameter is not
exceeded.
Proper Maintenance. All chucks must be properly
maintained and lubricated to achieve
maximum clamping force and withstand
the rigors of centrifugal force. To reduce
the risk of a thrown workpiece, follow all
maintenance intervals and instructions in
this document.
Disconnect Power. Serious entanglement or
impact injuries could occur if the lathe is
started while you are adjusting, servicing, or
installing the chuck. Always disconnect the
lathe from power before performing these
procedures.

Power Supply
Requirements
Availability
The full-load current rating is the amperage
a machine draws at 100% of the rated output
power. On machines with multiple motors, this is
the amperage drawn by the largest motor or sum
of all motors and electrical devices that might
operate at one time during normal operations.
The full-load current is not the maximum
amount of amps that the machine will draw. If
the machine is overloaded, it will draw additional
amps beyond the full-load rating.
If the machine is overloaded for a sufficient
length of time, damage, overheating, or fire may
result—especially if connected to an undersized
circuit. To reduce the risk of these hazards,
avoid overloading the machine during operation
and make sure it is connected to a power supply
circuit that meets the requirements in the

PREPARATION
Grounding Requirements
This machine must be grounded! In the event
of certain types of malfunctions or breakdowns,
grounding provides a path of least resistance
for electric current in order to reduce the risk of
electric shock.
Improper connection of the equipment-grounding
wire can result in a risk of electric shock. The
wire with green insulation (with or without
yellow stripes) is the equipment-grounding
wire. If repair or replacement of the power cord
is necessary, do not connect the equipment-
grounding wire to a live (current carrying)
terminal.
Check with a qualified electrician or service
personnel if you do not understand these
grounding requirements, or if you are in doubt
about whether the machine is properly grounded.
If you ever notice that a cord is damaged or
worn, disconnect it from power, and immediately
replace it with a new one.
440V Operation
As specified in the Circuit Requirements
section on the previous page, these machines
must be hardwired to the power source, using a
locking switch (see Figure 10).
These machines must also be connected to a
grounded metal permanent wiring system; or to a
system with an equipment-grounding conductor.
Due to the complexity and high voltage involved,
this type of installation MUST be done by an
electrician or qualified service personnel.

PREPARATION
The unpainted surfaces are coated at the factory
with a heavy-duty rust preventative that
prevents corrosion during shipment and storage.
The benefit of this rust preventative is that it
works very well. The downside is that it can be
time-consuming to thoroughly remove.
Be patient and do a careful job when cleaning
and removing the rust preventative. The time
you spend doing this will reward you with
smooth-sliding parts and a better appreciation
for the proper care of the unpainted surfaces.
A
lthough there are many ways to successfully
remove the rust preventative, the following
process works well in most situations.
Before cleaning, gather the following:
s $ISPOSABLErags
s #LEANERDEGREASER (certain citrus-based
degreasers work extremely well and they
have non-toxic fumes)
s 3AFETYGLASSESDISPOSABLEGLOVES

Before using these products, though, test them
on an inconspicuous area of a painted surface to
make sure they will not damage it.
Basic steps for removing rust preventative:
1. Put on safety glasses and disposable gloves.
2. #OATALLSURFACESTHATHAVERUSTPREVENTATIVE
with a liberal amount of your cleaner or
degreaser and let them soak for a few
minutes.
3. Wipe off the surfaces. If your cleaner or

4. Repeat Steps 2–3 as necessary until clean,
then coat all unpainted surfaces with a
quality metal protectant or light oil to
prevent rust.
GAS
Gasoline and petroleum
products have low flash
points and can explode
or cause fire if used for
cleaning. Avoid using these
products to remove rust
preventative.
Many cleaning solvents are
toxic if inhaled. Minimize
your risk by only using
these products in a well
ventilated area.
Avoid chlorine-based solvents, such as
acetone or brake parts cleaner that may
damage painted surfaces. Always follow the
manufacturer’s instructions when using any
type of cleaning product.
Cleaning & Protecting
Remove the end gear cover and end gears,
and use a stiff brush with mineral spirits
to clean the rust preventative from the
gears and shafts. DO NOT get any cleaner
or rust preventative on the V-belts, as it
could damage them or make them slip
during operations. If the belts do become
contaminated, replace them.

PREPARATION
Lifting & Moving
This machine and its parts are heavy! Serious
personal injury may occur if safe moving
methods are not used. To reduce the risk of a
lifting or dropping injury, ask others for help,
and use power equipment and guide rods.
Do not attempt to lift or move this lathe without
using the proper lifting equipment (such as
forklift or crane) or the necessary assistance from
other people. Each piece of lifting equipment
must be rated for at least 25% more than the
shipping weight of your lathe to support dynamic
loads that may be applied while lifting. Refer to
Things You'll Need on Page 21 for details.
To lift and move the lathe:
1. Remove the shipping crate top and sides,
then remove the small components from the
shipping pallet.
2. Move the lathe to its prepared location while
it is still attached to the shipping pallet.
3. Unbolt the lathe from the shipping pallet
4. To balance the load for lifting, move the
tailstock and carriage to the extreme right
end of the bedway, then lock them in place.
Note: Before attempting to move the carriage,
make sure the carriage lock is loose, the half
nut is disengaged, and the power feed is
disengaged (feed ON/OFF lever).
5. Position hardwood blocking under each
end of the bed as shown in Figure 14.
This will keep the lifting straps away from
the leadscrew, feed rod, and spindle rod to
prevent bending them during lifting.
Note: Fasten a center support between the
hardwood blocking to that they will stay
spread apart and in place when lifting (see
the example in Figure 15).

7. At each end of the lathe, have assistants
connect guide rods to safely keep the lathe
from swaying or tipping during lifting.
Leveling machinery helps precision components,
such as bedways, remain straight and flat during
the lifespan of the machine. Components on a
machine that is not level may slowly twist due to
the dynamic loads placed on the machine during
operation.
For best results, use a precision level that
is at least 12" long and sensitive enough to
show a distinct movement when a 0.003" shim
(approximately the thickness of one sheet of
standard newspaper) is placed under one end of
the level.
See the figure below for an example of a high
precision level.
Figure 17. Example of a precision level.
Leveling & Mounting
You must level your machine and either use
the included foot pads and leveling hardware or
bolt and shim your lathe to the floor. Because
mounting your lathe to the floor with permanent
hardware is an optional step and floor materials
may vary, floor mounting hardware is not
included.
Leveling
For accurate turning results and to prevent
warping the cast iron bed and ways, the lathe
bedways MUST be leveled from side-to-side
and from front-to-back on both ends.
Re-check the bedways 24 hours after
installation, two weeks after that, and then
annually to make sure they remain level.
8. Raise the lathe a couple of inches and check
the balance of the load.
— If the load is not safely balanced,
immediately lower the lathe and resolve
the issue before attempting to lift it
again.
9. Raise the lathe enough to clear the shipping
pallet, carefully remove the pallet, then
lower the lathe into position.
When lifting the lathe with straps, the load will
be top heavy. Take extra care to keep the load
balanced vertically and only lift it far enough
to remove the shipping pallet.
6. Attach the lifting straps to the power lifting
equipment (see Figure 16 for an example).

Assembly
With the exception of the handwheel handles, the
lathe is shipped fully assembled.
To install the handwheel handles, thread the
large handle into the carriage handwheel and the
small handle into the cross slide handwheel, as
shown in Figure 20.
To level the machine, use a precision level to
make sure the bedways are level from side-to-
side and from front-to-back.
— If using the included leveling pads (see
Figure 18), place them under the six
leveling jack bolt locations, then adjust
the bolts to level the lathe.
— If using mounting hardware that does not
allow for adjustment, level the lathe by
placing metal shims between the lathe
base and the floor before bolting it down.

Power Connection
After you have completed all previous setup
instructions and circuit requirements, the
machine is ready to be connected to the power
supply.
Due to the complexity required for planning,
bending, and installing the conduit necessary for
a code-compliant hardwire setup, an electrician
or qualified service personnel MUST perform this
type of installation.
Hardwire setups typically require power supply
wires to be enclosed inside of a solid or flexible
conduit, which is securely mounted at both ends
with the appropriate conduit fittings. All work
must adhere to the required electrical codes.
The hardwire setup must include a locking
disconnect switch (see Figure 21) between the
power source and the machine. This switch
serves as the means to completely disconnect
the machine from power to prevent electrocution
from accidental startup during adjustments,
maintenance, or service to the machine.

Spindle Break-In
Before subjecting the lathe to full loads, it
is essential to complete the spindle break-in
process as described below. This will ensure the
best results and maximum life of the precision
components inside the lathe.
The break-in procedure must be performed
in succession with the Test Run procedure
described in this manual, because many of the
test run steps prepare the lathe controls for the
break-in process.
Important: Do not perform the break-in
procedure independently from the Test Run
section—serious damage could occur to the lathe
if the controls are set differently than instructed
in that section.
Do not leave the lathe unattended during the
Spindle Break-In procedure. If your attention
is needed elsewhere during this procedure,
stop the lathe and restart the procedure later
from the beginning.

removes the workpiece.
To reduce the risk of
serious injury when using
this machine, read and
understand this entire
manual before beginning
any operations.
The purpose of this overview is to provide
the novice machine operator with a basic
understanding of how the machine is used durin
g

OPERATION
Chuck & Faceplate
Mounting
This lathe ships with the 3-jaw chuck installed.
This is a scroll-type chuck where all three jaws
move in unison when the chuck key is used.
The included 4-jaw chuck features independent
jaws, which are used for square or unevenly-
shaped stock, and to mount work that needs to
be adjusted to near zero total indicated runout.
If neither chuck can hold your workpiece, the
cast iron faceplate has slots for T-bolts that hold
standard or custom clamping hardware. With the
correct clamping hardware, this faceplate will
hold non-cylindrical parts.
Installation & Removal
Devices
Because chucks are heavy and often awkward to
hold, some kind of lifting, support, or protective
device should be used during installation or
removal. The weight and size of the chuck will
determine the appropriate device to use (refer to
the following figure for examples).

A dropped chuck can cause amputation,
serious crushing injuries, or property damage.
Always use a lifting, support, or protective
device to reduce this risk when installing or
removing a chuck.
This lathe is equipped with a D1-type spindle
nose. This type of spindle uses camlocks that are
adjusted with a chuck key to securely mount a
chuck or faceplate with repeatable precision and
ease.
Never use spindle speeds faster than the
chuck RPM rating or the safe limits of your
workpiece. Excessive spindle speeds greatly
increase the risk of the workpiece or chuck
being thrown from the machine with deadly
force!

Chuck Installation
To ensure accurate work, it is extremely
important to make sure the spindle nose and
chuck mating surfaces/tapers are clean. Even
a small amount of lint or debris can affect
accuracy.
The chuck is properly installed when all
camlocks are tight, the spindle and chuck tapers
firmly lock together, and the back of chuck is
firmly seated against the face of the spindle all
the way around—without any gaps.
Figure 31. Inserting camlock studs into spindle cam
holes.
INCORRECTCORRECT
5. Incrementally tighten the camlocks in a
criss-cross or star pattern to ensure that the
chuck seats evenly against the spindle.
6. When the chuck is fully seated and all the
camlocks are tight, verify that the cam line
is between the two "V" marks on the spindle
nose, as shown in the following figure.
— If the cam line is NOT between the "V"
marks when the camlock is tight, the stud
may be installed at the incorrect height.
To fix this, adjust the stud height as
shown in the following figure. Make sure
to re-install the stud cap screw afterward.
— If adjusting the stud height does not
correct the problem, try swapping stud
positions on the chuck.

process.
3. Clean and lightly oil the camlock studs, then
thoroughly clean the mating surfaces of the
spindle and chuck.
4. Install the chuck by inserting the camlock
studs straight into the spindle cam holes.
Important: Avoid inserting the studs by
pivoting them in from an angle or rotating
the spindle. This can damage studs or
spindle cam holes.

7. Verify that the chuck fits the spindle
properly by checking for any gaps between
the mating surfaces.
— If there are no gaps, proceed to Step 8.
— If there is a gap, remove the chuck, re-
clean the mating surfaces carefully, and
re-install. If the problem persists, contact
our Tech Support.
8. Verify that the chuck/spindle tapers
are seated firmly together by removing
the chuck, per the Chuck Removal
instructions, and pay close attention to how
easily the tapers release.
— If it was necessary to bump the chuck or
use a mallet to release the tapers, then
they are seating together properly.
— If the tapers released easily with little
intervention, they are not seated together
firmly as required. Remove the chuck, re-
clean the mating surfaces carefully, and
re-install. If the problem persists, contact
our Tech Support.
To remove the chuck:
1. DISCONNECT LATHE FROM POWER!
2. Use an appropriate lifting, support, or
protective device to protect the ways and
support the chuck (refer to Installation &
Removal Devices on Page 37).
3. Loosen the camlocks by turning the key
counterclockwise until each of the cam lines
are aligned with its corresponding spindle
mark (see Figure 35).
Tip: Camlocks can become very tight. A cheater
pipe may be used as a last resort to add
leverage when loosening. After loosening,
you may need to wiggle the chuck key in the
camlock to fully disengage the stud.
4. Using a dead blow hammer or other
soft mallet, lightly tap around the outer
circumference of the chuck body to loosen it
from the spindle.
5. Remove the chuck from the spindle, using
a light rocking motion to carefully slide the
studs out of the cam holes.
— If the chuck does not immediately come
off, rotate it approximately 60° and tap
it again. Make sure all the marks on the
cams and spindle are in proper alignment
for removal.

Scroll Chuck Clamping
This scroll-type chuck has an internal scroll-gear
that moves all jaws in unison when adjusted with
the chuck key. This chuck will hold cylindrical
parts on-center with the axis of spindle rotation
and can be rotated at high speeds if the
workpiece is properly clamped and balanced.
Never mix jaw types or positions to
accommodate an odd-shaped workpiece.
The chuck will spin out of balance and
may throw the workpiece! Instead, use an

Because of the dynamic forces involved in
machining a non-concentric or off-center
workpiece, always use a low spindle speed
to reduce risk of the workpiece coming loose
and being thrown from the lathe, which could
cause death or serious personal injury.
4-Jaw Chuck
Refer to the Chuck Installation (see Page 38)
and Chuck Removal (see Page 39) instructions
to install or remove the 4-jaw chuck.
The 4-jaw chuck features independently
adjustable hardened steel jaws for holding non-
concentric or off-center workpieces. Each jaw can
be independently removed from the chuck body
and reversed for a wide range of work holding
versatility.
Mounting Workpiece
1. DISCONNECT LATHE FROM POWER!
2. Place a chuck cradle or plywood on the
bedway below the chuck to protect the
bedway surfaces.
3. Use the chuck key to open each jaw so the
workpiece will lay flat against the chuck
face, jaw steps, or into the spindle opening.
4. With help from another person or a holding
device, position the workpiece so it is
centered in the chuck.

5. Tighten each jaw in small increments.
After you have adjusted the first jaw,
continue tightening the remaining jaws
in an opposing sequence, as shown by the
sequential order in Figure 37.
6. After the workpiece is held in place by the
jaws, use a dial indicator to make sure the
workpiece is centered in the chuck.
— If the workpiece is not correctly centered,
make fine adjustments by slightly
loosening one jaw and tightening the
opposing jaw until the workpiece is
correctly positioned (see Figure 38 for an
example).
Figure 38. Example photo of non-cylindrical workpiece
correctly mounted on the 4-jaw chuck.
Faceplate
Refer to the Chuck Installation (Page 38)
and Chuck Removal (Page 39) instructions to
install or remove the faceplate.
The faceplate included with your lathe can be
used for a wide range of operations, including
machining non-concentric workpieces, straight
turning between centers, off-center turning, and
boring.
The tools needed for mounting a workpiece will
vary depending on the type of setup you have.
Machining non-concentric workpieces at a
high speed could cause the workpiece to be
thrown from the spindle with deadly force at
the operator or bystanders. To reduce this
risk, only machine non-concentric workpieces
at low speeds and clamp counter-weights to
the faceplate to balance it.
Failure to properly secure a workpiece to the
faceplate could cause the workpiece to be
thrown from the lathe with deadly force at the
operator or bystanders. Use a minimum of
THREE independent clamping devices to hold
the workpiece onto the faceplate.

1. DISCONNECT LATHE FROM POWER!
2. Protect the bedway with a piece of plywood.
3. With help from another person or a holding
device to support the workpiece, position it
onto the faceplate and clamp it in place with
a minimum of three independent clamping
devices (see Figure 39 for an example).
Be sure to take into account the rotational
and cutting forces that will be applied to the
workpiece when clamping it to the faceplate.
If necessary, use counter-weights to balance
the assembly and use a dial indicator to
make sure that the workpiece is properly
positioned for your operation.

Using Quill
1. Move the quill lock lever toward the spindle
to unlock the quill.
2. Turn the tailstock handwheel clockwise
to move the quill toward the spindle or
counterclockwise to move it away from it.
3. Move the lock lever away from the spindle to
secure the quill in place.
Tailstock
The tailstock (see Figure 40) is typically used
to support long workpieces by means of a live or
dead center (refer to Centers on Page 46). It
can also be used to hold a drill or chuck to bore
holes in the center of a part. Custom arbors and
tapers can also be cut on your lathe by using the
offset tailstock adjustment.

OPERATION
Installing Tooling
This tailstock uses a quill with an MT#5 taper
that has a lock slot in the back of the bore that
accepts tang arbors and drill bits (see Figures
41–42 for examples).
Figure 41. Types of tapered arbors and tooling.
Tang

However, other tooling without tangs, such as
the four remaining tools shown in Figure 41,
can still be used if the potential load will not
exceed the strength of the tapered fit. For
example, this includes smaller drill chucks, drill
bits, and centers.
Note: If the tooling has an open hole in the end
but is too short to be exposed in the drift slot
for removal, then a screw can be threaded into
the end of the tool to provide a solid surface for
the quill pin to push against when the quill is
retracted for tool removal. Otherwise, removal of
such tooling may be difficult.
To install tooling in the tailstock:
1. With the tailstock locked in place, unlock the
quill, then use the handwheel to extend it
approximately 1".
2. Thoroughly clean and dry the tapered
mating surfaces of the quill and the center,
making sure that no lint or oil remains on
the tapers.
Note: If the tapered tool shaft has a tang, align
it with the slot in the back of the quill before
seating it.
3. With a firm and quick motion, insert the
tool into the quill. Check to see if it is firmly
seated by attempting to twist it—a firmly
seated tool will not twist.
4. Unlock the tailstock and move it until the tip
of the tool is close to, but not touching, the
workpiece, then re-lock the tailstock.
5. Start spindle rotation, unlock the quill, then
turn the tailstock handwheel clockwise to
feed the tool into the workpiece.

Offsetting Tailstock
The tailstock can be offset from the spindle
centerline for turning tapers. Move the tailstock
top casting toward the front of the lathe to
machine a taper at the tailstock end. Conversely,
position the tailstock top casting toward the back
of the lathe to machine a taper at the spindle
end.
Note: The marks on the offset indicator are
arbitrary. For a precise offset, use a dial
indicator to check quill movement while
adjusting the screws.

OPERATION
Aligning Tailstock to Spindle
Centerline
This is an essential adjustment that should be
verified or performed each time the tailstock
is used to turn concentric workpieces between
centers or immediately after offsetting the
tailstock when turning a taper. If the tailstock is
not aligned with the spindle centerline when it is
supposed to be, turning results will be inaccurate
along the length of the workpiece.

Precision Level ......................................................1
To align the tailstock to the spindle centerline:
1. Use the precision level to make sure the
bedway is level from side-to-side and from
front-to-back.
— If the bedway is not level, correct
this condition before continuing with
this procedure (refer to Leveling &
Mounting on Page 28).
2. Center drill both ends of one piece of round
stock, then set it aside for use in Step 5.
3. Use the other piece of round stock to make
a dead center, and turn it to a 60° point, as
illustrated in Figure 46.
Note: As long as this dead center remains in the
chuck, the point of the center will remain
true to the spindle centerline. The point will
have to be refinished whenever the center is
removed and then returned to the chuck.
4. Install a center in the tailstock.
5. Attach a lathe dog to the test stock from
Step 2, then mount it between the centers
(see Figure 47 for an example).

workpiece.
— If the test stock is thicker at the tailstock
end, move the tailstock toward the front of
the lathe 1⁄2 the distance of the amount of
taper (see Figure 48).
9. Repeat Steps 6–8 until the desired accuracy
is achieved.

Centers
Figure 50 shows the MT#5 dead centers
included with the lathe. In addition, an MT#7–
MT#5 tapered spindle sleeve is included for
mounting centers in the spindle.
Dead Centers
A dead center is a one-piece center that does not
rotate with the workpiece and is used to support
long, slender workpieces
Use the dead center in the spindle for operations
where the workpiece rotates with the center and
does not generate friction.
The carbide-tipped dead center can better
withstand the effects of friction and is best
used in the tailstock where the workpiece will
rotate against it. The tip of the center must be
generously lubricated during the operation to
avoid premature wear and maximize smooth
operation. Using low spindle speeds will also
reduce the heat and wear from friction.

OPERATION
Live Centers
A live center has bearings that allow the center
tip and the workpiece to rotate together; it can be
installed in the spindle and the tailstock quill for
higher speeds. However, a live center typically
does not provide the same level of rigidity as a
dead center, and final workpiece accuracy can
suffer as a result.
Mounting Dead Center in Spindle
1. DISCONNECT LATHE FROM POWER!
2. Thoroughly clean and dry the tapered
mating surfaces of the spindle bore, adapter
sleeve, and the center, making sure that no
lint or oil remains on the tapers.
Note: This will prevent the tapered surfaces from
seizing due to operational pressures, which
could make it very difficult to remove the
center.
3. Mount a chuck or faceplate onto the spindle,
whichever is correct for your operation.
4. Insert the center into the sleeve, then insert
the sleeve into the spindle bore through the
chuck or faceplate.
Figure 51 shows an example photo of a

3. Use the tailstock handwheel to feed the quill
out from the casting approximately 1".
Note: Do not extend the quill more than 2" or
stability and accuracy will be reduced.
4. Insert the center into the tailstock quill.
5. Seat the center firmly into the quill during
workpiece installation by rotating the quill
handwheel clockwise to apply pressure, with
the center engaged in the center hole in the
workpiece.
Note: Only apply enough pressure with
the tailstock quill to securely mount
the workpiece between centers. Avoid
overtightening the center against the
workpiece, or it may become difficult to
remove later, and it will result in excessive
friction and heat, which may damage the
workpiece and center.
Removing Center from Tailstock
To remove the center from the quill, hold onto it

OPERATION
Manual Feed
The handwheels shown in Figure 64 allow the
operator to manually move the cutting tool.
Carriage Handwheel
The carriage handwheel moves the carriage left
or right along the bed. It has a graduated dial
with 0.01" increments, and one full revolution
moves the carriage 0.80". Pull the handwheel out
to disengage it during power feed operations—
this will prevent entanglement hazards.
Cross Slide Handwheel
The cross slide handwheel moves the tool
toward and away from the work. Adjust the
position of the graduated scale by holding the
handwheel with one hand and turning the dial
with the other. The cross slide handwheel has
a direct-read graduated dial, which shows the
total amount of material removed from the
diameter of the workpiece (i.e., half the amount
of tool movement). The dial has 0.001" (0.02mm)
increments, and one full revolution moves the
slide 0.100" (5.08mm). Rotate the dial collar 180°
to read in metric units.
Compound Rest Handwheel
The compound rest handwheel moves the cutting
tool linearly along the set angle of the compound
rest. The compound rest angle is set by hand-
rotating it and securing in place with two hex
nuts. The compound rest has an indirect-read
graduated dial with 0.001" (0.02mm) increments.
One full revolution of the handwheel moves the
slide 0.100" (2.54mm). Rotate the dial collar 180°
to read in metric units.
Spindle Speed
Using the correct spindle speed is important
for safe and satisfactory results, as well as
maximizing tool life.
To set the spindle speed for your operation, you
will need to: 1) Determine the best spindle speed
for the cutting task, and 2) configure the lathe
controls to produce the required spindle speed.
Determining Spindle Speed
Many variables affect the optimum spindle speed
to use for any given operation, but the two most
important are the recommended cutting speed
for the workpiece material and the diameter of
the workpiece, as noted in the formula shown in
Figure 65.
Cutting speed, typically defined in feet per
minute (FPM), is the speed at which the edge of a
tool moves across the material surface.
A recommended cutting speed is an ideal speed
for cutting a type of material in order to produce
the desired finish and optimize tool life.
The books Machinery’s Handbook or Machine
Shop Practice, and some internet sites, provide
excellent recommendations for which cutting
speeds to use when calculating the spindle speed.
These sources also provide a wealth of additional
information about the variables that affect
cutting speed and they are a good educational
resource.
Also, there are a large number of easy-to-use
spindle speed calculators that can be found on
the internet. These sources will help you take
into account the applicable variables in order
to determine the best spindle speed for the
operation.

Both the carriage and cross slide have power feed
capability when the carriage is engaged with the
feed rod. The rate that these components move
(feed rate) is controlled by the headstock and
quick-change gearbox lever positions, and the
end gear configuration.
Feed rate and spindle speed must be considered
together. Keep in mind that the feed rate is
expressed in the amount of travel per revolution
of the spindle. The sources you use to determine
the optimum spindle speed for an operation will
also provide the optimal feed rate to use with
that spindle speed.
Often, the experienced machinist will use the
feeds and speeds given in their reference charts
or web calculators as a starting point, then
make minor adjustments to the feed rate (and
sometimes spindle speed) to achieve the best
results.
The carriage can alternatively be driven by the
leadscrew for threading operations. However,
this section only covers the use of the power
feed option for the carriage and cross slide
components for non-threading operations. To
learn how to power the carriage for threading
operations, refer to Threading on Page 59.
Power Feed
Operating the lathe at spindle speeds higher
than 350 RPM could result in gearbox damage
when the high (H) gearbox range is selected.
Always use spindle speeds of 350 RPM or
lower when using a high gearbox range.
Always make sure the variable speed dial is
turned all the way down (counterclockwise)
before starting spindle rotation. This will help
the operator remain in better control if spindle
rotation must be stopped immediately after
start-up for emergency reasons.

OPERATION
Power Feed Controls
Use Figures 68–72 and the following
descriptions to become familiar with the locations
and functions of the controls that you will use to
set up the correct power feed for your operation.
Note: Before using power feed, you may have to
re-configure the end gears, depending on how
they are set up. Refer to End Gears on Page 58
for detailed instructions.
Gearbox Range Lever: Selects the low or high
feed rate range by re-aligning the headstock
transfer gear. In the middle position, disables
power feed (see Figure 68).

Feed Selection Knob: Selects the carriage or
cross slide for power feed (see Figure 71).
When the knob is pulled out, the cross slide is
selected. Conversely, when the knob is pushed in,
the carriage is selected.
Figure 71. Apron feed selection and direction knobs.

In the middle position, the apron gears are
disengaged from the feed rod and neither
component will move.
Note: When using this control, you may need
to rock the handwheel of the component being
engaged so that the apron gears will mesh.
Apron Feed Direction Knob: Changes power feed
direction (see Figure 71).
When pushed in or pulled out, this knob quickly
reverses the power feed direction while the
spindle is rotating—without having to turn the
lathe off and use the feed direction lever on the
headstock.
Depending on the combined configuration
of the feed direction lever on the headstock
and the feed direction knob on the apron,
the actual direction of power feed may be
different from the printed indicators on the
machine!
Carriage Feed Clutch Knob: Adjusts how easily
the carriage clutch will disengage automatic
feeding when the carriage contacts a feed stop or
in the event of a crash. Tightening this knob all
the way disables the carriage clutch completely
(see Figure 72).
The carriage clutch serves two purposes: 1) It
disengages the carriage feed when the carriage
contacts a feed stop, providing a precise
repeatable stopping point; and 2) it provides
a safety factor in the event of an accidental
overload or crash.
The correct carriage clutch setting will depend
on variables of the operation, such as workpiece
material, depth of cut, power feed rate, and
others. Finding this clutch setting is a matter of
trial-and-error and experience.
For a starting point of clutch adjustment, rotate
the carriage feed clutch knob clockwise until it is
tight, then back it off counterclockwise three full
revolutions. This is a reasonably conservative
setting to start with. If necessary, further adjust
the knob for the setting that is right for your
operation.
The carriage clutch will not stop carriage
movement when it is engaged with the
leadscrew for threading.
If the carriage feed clutch knob is completely
tight (all the way clockwise), it will be
disabled, which will not allow it to help
prevent damage in event of a crash.

OPERATION
The chip drawer catches swarf and metal chips
during the machining process. It contains a
screen that keeps the large chips from returning
to the reservoir with the run-off coolant—this
prevents the chips causing pump damage.
Also, it slides open and is removable for cleaning
(see Figure 89).
Chip Drawer
Always use high quality coolant and follow the
manufacturer's instructions for diluting and
maintenance. The quick reference table shown
in Figure 91 can help you select the appropriate
fluid.
Refer to Coolant System Service on Page 75
for detailed instructions on how to add or change
fluid. Check the coolant regularly and promptly
change it when it becomes overly dirty or rancid,
or as recommended by the fluid manufacturer.

Turn-Nado® EVS Lathes OPERATION
To use the coolant system on your lathe:
1. Make sure the coolant tank is properly
serviced and filled with the appropriate
fluid, and that you are wearing the necessary
personal protection equipment.
2. Position the coolant nozzle for your
operation.
3. Use the coolant pump switch on the control
panel to turn the pump ON.
4. Adjust the flow of coolant by using the valve
lever near the base of the nozzle hose.
Important: Promptly clean any splashed fluid
from the floor to avoid a slipping hazard.
Running the pump without adequate fluid in
the coolant tank may permanently damage it,
which will not be covered under warranty.
Rod Support
Models SB1043PF, SB1045PF, and SB1061PF
include a rod support that gives additional
reinforcement to the leadscrew and feed rod (see
Figure 92).
Figure 92. Rod support.
Rod
Support
Ideally, the best position along the bed for the
rod support is mid-way between the right end of
the leadscrew and the farthest place toward the
tailstock that the carriage will travel during the
operation.
Use a 6mm hex wrench to loosen the cap screws
that secure the clamp plate, position the rod
support where desired, then re-tighten the cap
screws.
To avoid lathe damage, make sure the carriage
will not crash into the rod support when using
longitudinal power feed.

Maintenance Schedule
Cleaning & Protecting
Regular cleaning is one of the most important
steps in taking care of this lathe. We recommend
that the cleaning routine be planned into the
workflow schedule, so that adequate time is set
aside to do the job right.
Typically, the easiest way to clean swarf from
the bed ways and chip drawer is to use a wet/dry
shop vacuum that is dedicated for this purpose.
The small chips left over after vacuuming can be
wiped up with a slightly oiled rag. Avoid using
compressed air to blow off chips, as it may drive
them deeper into moving surfaces and could
cause sharp chips to fly into your face or hands.
Besides the ways, all other unpainted and
machined surfaces should be wiped down daily
to keep them rust-free and in top condition. This
includes any surface that is vulnerable to rust
if left unprotected (especially any parts that are
exposed to water-soluble coolant). Typically,
a thin film of oil is all that is necessary for
protection.
For optimum performance from this machine,
this maintenance schedule must be strictly
followed. We strongly recommend all operators
make a habit of following the daily maintenance
procedures. Use the chart provided on Page 67
to ensure this is done.

Lubrication
Headstock
The headstock has a pressurized lubrication
system that consists of an oil pump, an oil
pressure safety switch, a supply tank, oil hoses,
and a manifold with oil distribution lines. The oil
distribution lines direct oil to key locations, such
as the spindle bearings and upper headstock
gearing, to ensure that they always remain well
lubricated.
The oil pump automatically starts and begins
lubricating the headstock components when
the master power switch is turned ON and the
STOP button is reset. This ensures the headstock
bearings and gears are properly lubricated
before the spindle is started to protect these
components against damage from a dry start-up.
Review the lubrication system diagram
illustrated in Figure 97 to familiarize yourself
with the function and relationship of the
headstock oil system components.

Oil Pressure Safety Switch
To prevent costly damage to the headstock gears
and bearings from lack of adequate lubrication,
an oil pressure safety switch (see Figure 98) is
installed on the output side of the pump and will
shut the lathe down if oil pressure is lost for any
reason.
If the headstock components are not
adequately lubricated before and during
operation, lathe damage could occur. Never
bypass the oil pressure safety switch for any
reason.

Changing Headstock Oil
The headstock oil pump system must be cleaned
and the oil changed after the break-in period and
then annually (or every six months with heavy
service or extreme working conditions).
Since this lathe uses a base-mounted oil tank,
removing the drain plug and using a drain pan
is not a convenient option when changing the oil.
We recommend using a remote oil pump with a
suction hose that can be inserted through the
filler spout to the bottom of the oil tank instead.
If a remote oil pump system is not available,
use the headstock oil pump for this purpose, as
instructed below.

To to change the headstock oil:
1. DISCONNECT LATHE FROM POWER!
2. Remove the end gear cover, the tank access
cover, and the oil tank fill cap.
3. Remove the headstock oil supply line from
the check valve (see Figure 101).
4. Push the drain hose onto the headstock oil
supply line. If necessary, use a hose clamp to
ensure a tight connection.
5. Hold the other end of the drain tube in the
bucket, then turn the master power switch
ON and reset the STOP button. The oil
pump will start pumping oil from the tank
and into the bucket.
6. As soon as you hear a sucking sound from
the tank or when the oil slows or stops
flowing out, turn the master power switch
OFF to stop the pump.
7. Remove the drain hose and re-connect the
headstock oil supply line to the check valve.
8. Place rags under the tank outlet cover to
catch the residual oil in the tank when
the cover is removed in the next step (see
Figure 102).
9. Remove the pump suction line from the tank
outlet cover, remove the three cap screws
that secure the cover, then carefully remove
the cover.
10. Use mineral spirits and rags to clean the
inside of the tank. Make sure to soak up any
excess mineral spirits with dry rags so that
it does not stay in the tank and contaminate
the oil.
Tip: Consider placing one or two magnets at the
bottom of the tank to collect any fine metal
particles. This will make cleaning easier the
next time around and reduce the amount of
metal particles that may end up in the oil.
11. Re-install the tank outlet cover with a new

One-Shot Oiler
The one-shot oiler shown in Figure 107
lubricates the saddle ways with oil from the
apron reservoir.
To use the one-shot oiler, pull the pump knob out
for two or three seconds and then push it in. The
pump draws oil from the apron reservoir and
then forces it through drilled passages to the way
guides.
Repeat this process while moving the carriage
and cross slide through their full range of
movement to distribute oil along the ways.
Lubricate the guides before and after operating
the lathe. If the lathe is in a moist or dirty
environment, increase the lubrication interval.
Check the apron oil level through the sight glass
before using the one-shot oiler to ensure the
proper oil level.
Draining Oil & Flushing Reservoir
Since the apron oil reservoir supplies the one-
shot oiler, the oil is constantly being refreshed
when the reservoir is filled. However, small
metal particles may accumulate at the bottom of
the reservoir with normal use. Therefore, to keep
the reservoir clean, drain and flush it at least
once a year.
Place a catch pan under the apron drain plug
shown in Figure 106, loosen the fill plug, then
use a 6mm hex wrench to remove the drain plug
and empty the reservoir.

metal needle or lance tips, as they can push the
ball too far into the oiler, break the spring seat,
and lodge the ball in the oil galley.
Lubricate the ball oilers before and after machine
use, and more frequently under heavy use. When
lubricating ball oilers, first clean the outside
surface to remove any dust or grime. Push the
rubber or plastic tip of the oil can nozzle against
the ball oiler to create a hydraulic seal, then
pump the oil can once or twice. If you see sludge
and contaminants coming out of the lubrication
area, keep pumping the oil can until the oil runs
clear. When finished, wipe away any excess oil.

End Gears
Grease Type ............................................... NLGI#2
Frequency ................ Annually or When Changing
The end gears, shown in Figure 111, should
always have a thin coat of heavy grease to
minimize corrosion, noise, and wear. Wipe away
excess grease that could be thrown onto the
V-belts and reduce optimal power transmission
from the motor.
Figure 111. End gears.
Handling & Care
Make sure to clean and lubricate any gears
you install or change. Be very careful during
handling and storage—the grease coating on the
gears will easily pickup dirt or debris, which can
then spread to the other gears and increase the
rate of wear.
Make sure the end gear cover remains installed
whenever possible to keep the gears free of dust
or debris from the outside environment.
Lubricating
1. DISCONNECT LATHE FROM POWER!
2. Remove the end gear cover and all the end
gears shown in Figure 111.
3. Clean the end gears thoroughly with mineral
spirits to remove the old grease. Use a small
brush if necessary to clean between the
teeth.
4. Clean the shafts, and wipe away any grease
splatters in the vicinity and on the inside of
the end gear cover.
5. Using a clean brush, apply a thin layer of
grease on the gears. Make sure to get grease
between the gear teeth, but do not fill the
teeth valleys.
6. Install the end gears and mesh them
together with an approximate 0.002"
backlash. Once the gears are meshed
together, apply a small dab of grease
between them where they mesh together—
this grease will be distributed when the
gears rotate and re-coat any areas scraped
off during installation.
7. Re-install the end gear cover before re-
connecting the lathe to power.

MAINTENANCE
Coolant System
Service
The coolant system consists of a fluid tank,
pump, and flexible nozzle. The pump pulls fluid
from the tank and sends it to the valve, which
controls the flow of coolant to the nozzle. As the
fluid leaves the work area, it drains back into
the tank through the chip drawer and catch tray
where the swarf is screened out.
Use Figures 112–113 to identify the locations of
the coolant system controls and components.
Although most swarf from machining operations
is screened out of the coolant before it returns
to the tank, small particles will accumulate in
the bottom of the tank in the form of sludge. To
prevent this sludge from being pulled into the
pump and damaging it, the pump’s suction tube
is positioned a couple inches from the bottom
of the tank and fitted with a fine screen. This
works well when the tank is regularly cleaned;
however, if too much sludge is allowed to
accumulate before the tank is cleaned, the pump
will inevitably begin sucking it up.
Hazards
As coolants ages and gets used, dangerous
microbes can proliferate and create a biological
hazard. The risk of exposure to this hazard can
be greatly reduced by replacing the old fluid
on a monthly basis, or as indicated by the fluid
manufacturer.
The important thing to keep in mind when
working with the coolant is to minimize exposure
to your skin, eyes, and lungs by wearing the
proper PPE (Personal Protective Equipment),
such as splash-resistant safety goggles, long-
sleeve waterproof gloves, protective clothing, and
a NIOSH approved respirator.
BIOLOGICAL & POISON
HAZARD!
Use the correct personal
protection equipment when
handling coolant. Follow

To change the coolant:
1. Position the coolant nozzle over the back of
the backsplash so that it is pointing behind
the lathe.
2. Place the 5-gallon bucket behind the lathe
and under the coolant nozzle. If you are
using the optional hose, connect it to the
nozzle and place it in the bucket. Otherwise,
you may need to have another person hold
the bucket up to the nozzle to prevent
coolant from splashing out.
3. Turn the coolant pump ON and pump the
old fluid out of the reservoir. Turn the pump
OFF immediately after the fluid stops
flowing.
Adding Fluid
1. DISCONNECT LATHE FROM POWER!
2. Remove the vented access cover from the
rear of the right stand, then slide the tank
out, as shown in Figure 114.
Running the coolant pump without adequate
fluid in the tank may permanently damage it,
which will not be covered under warranty.
3. Pour coolant into the tank until it is nearly
full.
4. Slide the tank back into the cabinet and
replace the access cover.
Changing Coolant
When you replace the old coolant, take the time
to thoroughly clean out the chip drawer, catch
tray, and fluid tank. The entire job only takes
about a 1⁄2 hour when you are prepared with the
proper materials and tools. Make sure to dispose
of old fluid according to federal, state, and fluid

Tip: Leave one or more magnets at the bottom
of the tank to collect metal chips and make
cleanup easier next time. This will also help
keep small metal chips out of the pump.
10. Refill the tank with new coolant, then slide it
completely into the base.
11. Replace the access cover panel.

13. Turn the master power switch ON, then
reset the STOP button.
14. Turn the coolant pump ON to verify that
fluid cycles properly, then turn it OFF.
Machine Storage
To prevent the development of rust and
corrosion, the lathe must be properly prepared
if it will be stored for a long period of time.
Doing this will ensure the lathe remains in good
condition for later use.
To prepare the lathe for storage:
1. Run the lathe and bring all gearboxes to
operating temperature, then drain and refill
them with clean oil.
2. Pump out the old coolant, then add a few
drops of way oil and blow out the lines with
compressed air.
3. DISCONNECT LATHE FROM POWER!
4. Thoroughly clean all unpainted, bare metal
surfaces, then apply a liberal coat of way
oil, heavy grease, or rust preventative. Take
care to ensure these surfaces are completely
covered but that the rust preventative or
grease is kept off of painted surfaces.
5. Lubricate the machine as outlined in the
lubrication section. Be sure to use an oil can
to purge all ball oilers and oil passages with
fresh oil.
6. Loosen or remove the V-belts so they do not
become stretched during the storage period.
(Be sure to place a maintenance note near
the power button as a reminder that the
belts have been loosened or removed.)
7. Place a few moisture absorbing desiccant
packs inside of the electrical box.
8. Cover the lathe and place it in a dry area
that is out of direct sunlight and away from
hazardous fumes, paint, solvents, or gas.
Fumes and sunlight can bleach or discolor
paint and make the chuck guard cloudy.
9. Every few months, rotate by hand all gear-
driven components a few times in several
gear selections. This will keep the bearings,
bushings, gears, and shafts well lubricated
and protected from corrosion—especially
during the winter months.
Slide the carriage, micrometer stop,
tailstock, and steady rest down the lathe
bed to make sure that way spotting is not
beginning to occur.

The cross slide backlash is adjusted by loosening
all four cap screws shown in Figure 116, then
tightening the center set screw. This will push
down on a wedge and force the leadscrew nut
apart, taking up lash between the nut and
leadscrew.
Backlash Adjustment
Backlash is the amount of free play felt while
changing rotation directions with the handwheel.
This can be adjusted on the compound rest
and cross slide leadscrews. Before beginning
any adjustment, make sure that all associated
components have been cleaned and lubricated.
Compound Rest
Tools Needed: Qty
Hex Wrench 3mm .................................................1
The compound rest backlash is adjusted by
tightening the set screws shown in Figure
115. When these screws are adjusted against
the leadscrew nut, they offset part of the nut to
remove play between the nut and leadscrew.
Figure 115. Compound rest backlash adjustment set
screws.
Set Screws
Reducing backlash to less than 0.002" is
impractical and can lead to accelerated wear
of the wedge, nut, and leadscrew. Avoid the
temptation to overtighten the backlash set
screw while adjusting.
To adjust the backlash, rock the handwheel back
and forth, and tighten the screws slowly until
the backlash is approximately 0.002"–0.003", as
indicated on the graduated dial.
If you end up adjusting the nut too tight, loosen
the set screws, tap the compound rest a few
times with a rubber or wooden mallet, and turn
the handwheel slowly back and forth until it
moves freely—then try again.
To adjust the backlash, remove the compound
rest and loosen the four cap screws. Then, rock
the cross slide handwheel back and forth, and

Gib Adjustment
The goal of adjusting the gib screws is to remove
sloppiness or "play" from the ways without over-
adjusting them to the point where they become
stiff and difficult to move.
In general, loose gibs cause poor finishes and
tool chatter; however, over-tightened gibs cause
premature wear and make it difficult to turn the
handwheels.
Important: Before adjusting the gibs, loosen the
locks for the device so that the gibs can freely
slide during adjustment, then lubricate the ways.
The gibs are tapered and held in position by a
screw at each end. To adjust the gib, turn one
screw 1⁄4 turn clockwise and the other screw 1⁄4
turn counterclockwise, so both screws move in
the same direction and the same amount. Test
the feel of the sliding component by turning
the handwheel, and adjust the gib screws as
necessary to make it tighter or looser.
The gib adjustment process usually requires
some trial-and-error. Repeat the adjustment
process as necessary until you find the best
balance between loose and stiff movement. Most
machinists find that the ideal gib adjustment is
one where a small amount of drag or resistance
is present, yet the handwheels are still easy to
move.

tightened by two set screws. Use this procedure
to adjust the half nut if it becomes loose from
wear, or it is too tight for your preferences. A
half nut that is too loose will make it difficult
to produce accurate work. A half nut that is too
tight will increase the rate of wear on itself and
the leadscrew.

The leadscrew is secured to a connecting collar
that is part of the headstock drivetrain with
the use of a soft-metal shear pin. The shear pin
is designed to break and disengage the power
transfer to the leadscrew to help protect more
expensive lathe components in the case of a
carriage crash or the lathe is overloaded.
Contact South Bend to order a replacement shear
pin (Part Number PSB10160927) or use the
specifications in Figure 131 to fabricate your
own.
4. Put on safety glasses.

3. Rotate the shroud washer on the leadscrew
(see Figure 133) so that the cutout lines up
with the shear pin head.
If you fabricate your own shear pin, make sure
to use the material and dimensions specified
in Figure 131. Otherwise, the shear pin may
not provide the intended protection and lathe
damage could result.
To replace the shear pin:
1. DISCONNECT LATHE FROM POWER!
2. Clean debris and grime from the shear pin
area (see Figure 132).

8. Put on safety goggles, insert the blow gun tip
into the shear pin hole and blow out the hole
with compressed air.
9. Put a drop of oil in the hole, then insert the
new shear pin into the bore, as shown in
Figure 136.
Note: If the pin does not freely slide into the
bore, DO NOT use a hammer on the pin or
you may permanently damage the shear
mechanism and bore, which would make
it nearly impossible to remove if it breaks
again. Instead, take the time to carefully
line up the two bores so it slides in easily.
Chamfer the end of the pin if necessary to
make it easier to insert.
10. With the pin completely seated in the bore
and the head flush with the leadscrew
shoulder, slide the shroud washer against
the shoulder, then rotate the washer 180° to
completely cover the head of the shear pin,
as shown in Figure 137.

gap insert that the saddle rides on, then test
the flanks of the prisms.
8. Tighten the gap bed cap screws in an
alternating manner and tap the side of the
gap insert into alignment.
9. Inspect the gap alignment 24 hours later
to make sure the gap is still aligned. If
necessary, loosen the gap bed cap screws and
repeat Steps 7–8 until the insert is properly
aligned.
Gap Installation
1. Use mineral spirits and a clean lint-free rag
to clean the mating surfaces of the gap, bed,
and ways. If necessary, stone the mating
surfaces to remove scratches, dings, or burrs.
2. Wipe a thin layer of light machine oil on the
mating surfaces.
3. Place the gap insert into the gap and use a
dead-blow hammer to align the insert with
the lathe bed.
4. Back off the dowel pin jack nuts, and lightly
tap the dowel pins back into their respective
holes until they are seated. This process will
further help align the gap insert and bed
mating surfaces.

Electrical Safety Instructions
These pages are accurate at the time of printing. In the constant effort to improve, however, we may
make changes to the electrical systems of future machines. Study this section carefully. If you see
differences between your machine and what is shown in this section, call Technical Support at (360)
734-1540 for assistance BEFORE making any changes to the wiring on your machine.
Shock Hazard: It is extremely dangerous to
perform electrical or wiring tasks while the
machine is connected to the power source.
Touching electrified parts will result in
personal injury including but not limited to
severe burns, electrocution, or death. For
your own safety, disconnect machine from
the power source before servicing electrical
components or performing any wiring tasks!
Wire Connections: All connections must be
tight to prevent wires from loosening during
machine operation. Double-check all wires
disconnected or connected during any wiring
task to ensure tight connections.
Modifications: Using aftermarket parts or
modifying the wiring beyond what is shown
in the diagram may lead to unpredictable
results, including serious injury or fire.
Motor Wiring: The motor wiring shown in these
diagrams is current at the time of printing,
but it may not match your machine. Always
use the wiring diagram inside the motor
junction box.
Circuit Requirements: Connecting the machine
to an improperly sized circuit will greatly
increase the risk of fire. To minimize
this risk, only connect the machine to a
power circuit that meets the minimum
requirements given in this manual.
Capacitors/Inverters: Some capacitors and
power inverters store an electrical charge for
up to 10 minutes after being disconnected
from the power source. To reduce the risk of
being shocked, wait at least this long before
working on capacitors.
Wire/Component Damage: Damaged wires
or components increase the risk of serious
personal injury, fire, or machine damage. If
you notice that any wires or components are
damaged while performing a wiring task,
replace those wires or components before
completing the task.
Experiencing Difficulties: If you are
experiencing difficulties understanding the
information included in this section, contact
our Technical Support at (360) 734-1540.

Correcting Phase
Polarity
This sub-section is only provided for
troubleshooting. If you discover during the test
run that the lathe will not operate, or that the
spindle runs backwards, the lathe may be wired
out of phase.
Without the proper test equipment to determine
the phase of power source legs, wiring machinery
to 3-phase power may require trial-and-error.
Correcting this is simply a matter of reversing
the positions where two of the incoming power
source wires are connected.
To correct wiring that is out of phase:
1. Push the STOP button, turn the master
power switch to OFF, and disconnect the
machine from power.
2. Open the electrical box and swap any two
hot wires coming from the power supply, as
illustrated in Figure 141.
3. Close and latch the electrical box, and
reconnect the machine to the power source.
Swap any two
of these wires
