The purpose of safety symbols is to attract your attention to possible hazardous conditions.
This manual uses a series of symbols and signal words intended to convey the level of importance of the safety messages. The progression of symbols is described below. Remember that
safety messages by themselves do not eliminate danger and are not a substitute for proper
accident prevention measures.
Indicates an imminently hazardous situation which, if not avoided,
WILL result in death or serious injury.
Indicates a potentially hazardous situation which, if not avoided,
COULD result in death or serious injury.
Indicates a potentially hazardous situation which, if not avoided,
MAY result in minor or moderate injury. It may also be used to alert
against unsafe practices.

NOTICE

This symbol is used to alert the user to useful information about
proper operation of the machine.

For your own safety and protection of
property, consult a qualified electrician if
you are unsure about wiring practices or
electrical codes in your area.
Note: The circuit requirements listed in this manual apply to a dedicated circuit—where only one
machine will be running at a time. If this machine
will be connected to a shared circuit where multiple machines will be running at the same time,
consult a qualified electrician to ensure that the
circuit is properly sized for safe operation.

Basic steps for removing rust preventative:

Gasoline or products
with low flash points can
explode or cause fire if
used to clean machinery. Avoid cleaning with
these products.

Many cleaning solvents
are toxic if concentrated amounts are inhaled.
Only work in a well-ventilated area.

NOTICE
Avoid chlorine-based solvents, such as
acetone or brake parts cleaner, that may
damage painted surfaces. Test all cleaners
in an inconspicuous area before using to
make sure they will not damage paint.

NOTICE
During the first 16 hours of use, the V-belts
will stretch and seat into the pulley grooves.
The V-belts must be properly re-tensioned
after this period to avoid reducing their useful life. Refer to V-Belts Service on Page 83

Tip: When the camlock studs are correctly installed
and adjusted, and the chuck or faceplate mounts
evenly onto the spindle, make opposing and
unique matching registration marks on the sides
of the spindle and chuck/faceplate. Align these
registration marks when you next mount the chuck
or faceplate to ensure that the correct spindle
mounting hole is used by each stud.

NOTICE
Never install a chuck or faceplate without
having the stud locking cap screws in
place or fully tightened. If the cap screws
are loose, the camlock studs could rotate
with the camlocks, which could make the
removal of the chuck or faceplate nearly
impossible.

Because of the dynamic forces involved in
machining a non-concentric or off-center
workpiece, always use a low spindle speed
to prevent the workpiece breaking loose and
being thrown from the lathe, which could
lead to death or serious personal injury.

Tip: If setting up to cut external right-hand
inch or metric threads, or internal left-hand
threads for the first time, set the compound
rest so its travel is perfectly parallel with the
cross slide. Using a protractor, rotate the
compound 29.5° counterclockwise and mark
the new location on the cross slide. This mark
will be the quick reference point for setting
the offset angle. To mark for internal righthand threads, or external left hand threads,
repeat this process, but rotate the rest 29.5°
clockwise and mark the cross slide accordingly.

Over-extending a cutting tool from the tool
post will increase the risk of it breaking during operation, which may cause metal pieces
to be thrown with great force at the operator
or bystanders. Only extend a cutting tool 2.5
times the width of its cross-section or less
(e.g., 2.5 x 0.5" = 1.25").

NOTICE
When the carriage is engaged with the
leadscrew during threading operations,
these stops WILL NOT stop carriage movement—you MUST use the halfnut lever
instead. Otherwise, the carriage can crash
into the chuck or the leadscrew shear pin
can break.
Before doing any threading operations,
make sure the carriage stops WILL NOT
meet during the operation.

NOTICE
Even though there is a lock-out device in
the apron to prevent the feed control knob
and the halfnut lever from being engaged at
the same time, this device could break with
enough force. Attempting to engage feed
control knob and the halfnut lever at the
same time could cause severe lathe damage and will void the warranty.
If you attempt to use the controls on the
headstock above the control panel to make
changes when the spindle is rotating, the
headstock gearing will suffer damage!
ALWAYS make sure the spindle is completely stopped BEFORE using the headstock controls to make changes.

NOTICE
When threading, we recommend you use
the slowest speed possible and make multiple light cuts. This will give you better control of when to engage/disengage the halfnut and prevent damaging the workpiece or
lathe.

NOTICE
The thread dial is not used for metric or
fractional TPI threading. You must leave the
halfnut lever engaged from the beginning
until the threads are complete for these
threading operations.

General Note: Cutting fluids are used for heavy-duty lathe operations and production turning. Oil-water emulsions and synthetic
cutting fluids are the most common for typical lathe operations. Sulferized oils often are used for threading. For small projects,
spot lubrications can be done with an oil can or brush, or omitted completely.

Running the cutting fluid pump without
adequate fluid in the reservoir may permanently damage it, which will not be covered
under warranty.

",%"



Note: It may take a few seconds for the pump
to start circulating the fluid. If the fluid does
not start flowing within the first minute, turn
the pump OFF to prevent damaging it. Try
priming the pump manually by pouring cutting
fluid down into the nozzle, then repeat Step
11.

If the brake fluid reservoir becomes empty,
air could be introduced into the hydraulic
lines. This will greatly reduce the effectiveness of the brake system in stopping the
spindle. To correct this condition, perform
the Bleeding Brake System procedure on
Page 86.

the brake pads are equally centered on the

Note: If there is air in the brake line, foam or
bubbles may appear first. Keep pumping the
brake pedal until there is a stream of brake
fluid coming out of the bleeder hole, then continue pumping until there is no further fluid.

Important: Continually monitor the brake
fluid lever in the reservoir during the next
steps and make sure that it stays full. If the
reservoir empties, air will be forced into the
hydraulic line and you will have to re-start this
part of the procedure again.

Note: Threading the set screws in will increase
the pressure on the compression springs that
force the steel balls into the indents of the
clutch. This will make it easier for the clutch
to slip when necessary.
Threading the set screws out will decrease
this pressure and make it harder for the
clutch to slip.
Important: Do not thread the set screws in
so much that the feedrod clutch will not slip if
the carriage meets resistance.

Tip: Apply a small amount of silicone grease
to the O-rings to keep them in place on
the intermediate plate as you re-assemble
the caliper. Do not use a petroleum-based
grease that can swell the O-rings.

Note: Do not immerse the caliper housings
in brake cleaner. This will contaminate the
brake fluid contained in the housings and
under the pistons.

Important: Continually monitor the brake
fluid lever in the reservoir and make sure that
it stays full. If the reservoir empties, additional
air will be forced into the hydraulic line and
you will have to re-start this procedure from
the beginning.

NOTICE
If you must drill out the shear pin pieces,
use a drill bit 1 ⁄ 8" or smaller. If the dimensions of the tapered hole are changed when
drilling, the leadscrew and hub will be damaged and the shear pin will not stay in the
