Additional Safety for Wood Lathes
MAIN INJURY HAZARDS: Death or crushing injury from getting entangled in rotating spindle
or workpiece; death, blindness, or broken bones from being struck by a workpiece that breaks
apart or comes loose during rotation, turning tool kickback, or flying wood chips. To minimize
your risk of these hazards, always heed the following warning information:
INTEGRITY OF STOCK. Verify each workpiece
is free of knots, splits, nails, or foreign material
to ensure it can safely rotate on spindle without
breaking apart or causing turning tool kickback.
WORKPIECE PREPARATION. Before mounting,
cut off waste portions with a bandsaw or other tool
to ensure workpiece has no large edges to catch
turning tool, and it will rotate without dangerous
wobbling.
SECURING LOCKS. Verify tool rest, headstock,
and tailstock are secure before turning lathe ON.
SECURING WORKPIECE. An improperly secured
workpiece can fly off spindle with deadly force.
Use proven setup techniques and always verify
workpiece is well-secured before starting lathe.
Only use high-quality fasteners with non-tapered
heads for faceplate attachment.
TOOL SUPPORT. An improperly supported tool
may be grabbed or ejected. Adjust tool rest
approximately 1⁄4" away from workpiece and 1⁄ 8"
above workpiece center line to provide proper
support for turning tool. Firmly hold turning tool
with both hands against tool rest.
TOOL KICKBACK. Occurs when turning tool is
ejected from workpiece with great force, striking
operator or bystanders. Commonly caused by
poor workpiece selection/preparation, improper
tool usage, or improper machine setup or tool rest
adjustment.

EYE/FACE PROTECTION. Always wear a face
shield and safety glasses when operating lathe.
PROPER APPAREL. Do not wear gloves, necktie
or loose clothing. Keep keep long hair away from
rotating spindle.
SPEED RATES. Select correct spindle speed for
workpiece size, type, shape, and condition. Use
low speeds when roughing or when turning large,
long, or non-concentric workpieces. Allow spindle
to reach full speed before turning.
NEW SETUPS. Test each new setup by starting
spindle rotation at the lowest speed and standing
to the side of the lathe until workpiece reaches full
speed and you can verify safe rotation.
ROUGHING. Use correct tool. Take light cuts,
use low speeds, and firmly support tool with both
hands.
SHARP TOOLS. Only use sharp turning tools—
they cut with less resistance than dull tools. Dull
turning tools can catch or grab and pull your
hands into the rotating workpiece.
STOPPING SPINDLE. Always allow spindle to
completely stop on its own. Never put hands or
another object on spinning workpiece.
ADJUSTMENTS/MAINTENANCE. Make sure
wood lathe is turned OFF, disconnected from
power, and all moving parts are completely stopped
before doing adjustments or maintenance.

ADJUSTMENT TOOLS. Remove all chuck keys,
wrenches, and adjustment tools before turning
lathe ON. A tool left on the lathe can become a
deadly projectile when spindle is started.

MEASURING WORKPIECE. Only measure workpiece after it has stopped. Trying to measure a
spinning workpiece increases entanglement risk.

SAFE CLEARANCES. Before starting spindle,
verify workpiece has adequate clearance by handrotating it through its entire range of motion.

SANDING/POLISHING. To reduce entanglement
risk, remove tool rest before sanding. Never completely wrap sandpaper around workpiece.

SECTION 2: POWER SUPPLY
Availability
Before installing the machine, consider the availability and proximity of the required power supply
circuit. If an existing circuit does not meet the
requirements for this machine, a new circuit must
be installed. To minimize the risk of electrocution,
fire, or equipment damage, installation work and
electrical wiring must be done by an electrician or
qualified service personnel in accordance with all
applicable codes and standards.

Electrocution, fire, or
equipment damage may
occur if machine is not
correctly grounded and
connected to the power
supply.

Full-Load Current Rating
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.
T25920 Full-Load Current Rating..............5.3A
T25926 Full-Load Current Rating..............6.0A
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 specified circuit requirements.

Model T25920/T25926 (Mfd. Since 08/14)

Serious injury could occur if you connect
the machine to power before completing the
setup process. DO NOT connect to power
until instructed later in this manual.

110V Circuit Requirements
This machine is prewired to operate on a power
supply circuit that has a verified ground and meets
the following requirements:
Nominal Voltage......................................... 110V
Cycle...........................................................60 Hz
Phase............................................ Single-Phase
Power Supply Circuit.......................... 15 Amps
A power supply circuit includes all electrical
equipment between the breaker box or fuse panel
in the building and the machine. The power supply circuit used for this machine must be sized to
safely handle the full-load current drawn from the
machine for an extended period of time. (If this
machine is connected to a circuit protected by
fuses, use a time delay fuse marked D.)

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

-11-

Grounding & Plug Requirements
This machine MUST be grounded. In the event
of certain malfunctions or breakdowns, grounding
reduces the risk of electric shock by providing a
path of least resistance for electric current.
This machine is equipped with a power cord that
has an equipment-grounding wire and a grounding
plug. Only insert plug into a matching receptacle
(outlet) that is properly installed and grounded in
accordance with all local codes and ordinances.
DO NOT modify the provided plug!

Grounding Prong

5-15 PLUG
Neutral Hot

Figure 6. Typical 5-15 plug and receptacle.

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 or plug 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 tool is properly grounded. If you ever notice
that a cord or plug is damaged or worn, disconnect it from power, and immediately replace it with
a new one.

Extension Cords
We do not recommend using an extension cord
with this machine. If you must use an extension
cord, only use it if absolutely necessary and only
on a temporary basis.
Extension cords cause voltage drop, which can
damage electrical components and shorten motor
life. Voltage drop increases as the extension cord
size gets longer and the gauge size gets smaller
(higher gauge numbers indicate smaller sizes).
Any extension cord used with this machine must
be in good condition and contain a ground wire
and matching plug/receptacle. Additionally, it must
meet the following size requirements:
Minimum Gauge Size............................14 AWG
Maximum Length (Shorter is Better).......50 ft.

SHOCK HAZARD!
Two-prong outlets do not meet the grounding
requirements for this machine. Do not modify
or use an adapter on the plug provided—if
it will not fit the outlet, have a qualified
electrician install the proper outlet with a
verified ground.

Inventory

Cleanup

The following is a list of items shipped with your
machine. Before beginning setup, lay these items
out and inventory them.

The unpainted surfaces of your machine are
coated with a heavy-duty rust preventative that
prevents corrosion during shipment and storage.
This rust preventative works extremely well, but it
will take a little time to clean.

If any non-proprietary parts are missing (e.g. a
nut or a washer), we will gladly replace them; or
for the sake of expediency, replacements can be
obtained at your local hardware store.

G. Live Center.................................................. 1

Be patient and do a thorough job cleaning your
machine. The time you spend doing this now will
give you a better appreciation for the proper care
of your machine's unpainted surfaces.
There are many ways to remove this rust preventative, but the following steps work well in a wide
variety of situations. Always follow the manufacturer’s instructions with any cleaning product you
use and make sure you work in a well-ventilated
area to minimize exposure to toxic fumes.
Before cleaning, gather the following:
•
Disposable rags
•
Cleaner/degreaser (WD•40 works well)
•
Safety glasses & disposable gloves
•
Plastic paint scraper (optional)

G

Basic steps for removing rust preventative:
D
F

Put on safety glasses.

Coat the rust preventative with a liberal
amount of cleaner/degreaser, then let it soak
for 5–10 minutes.

Wipe off the surfaces. If your cleaner/degreaser is effective, the rust preventative will wipe
off easily. If you have a plastic paint scraper,
scrape off as much as you can first, then wipe
off the rest with the rag.

Repeat Steps 2–3 as necessary until clean,
then coat all unpainted surfaces with a quality
metal protectant to prevent rust.

SECTION 4: OPERATIONS
The purpose of this overview is to provide the novice machine operator with a basic understanding
of how the machine is used during operation, so
the machine controls/components discussed later
in this manual are easier to understand.
Due to the generic nature of this overview, it is
not intended to be an instructional guide. To learn
more about specific operations, read this entire
manual and seek additional training from experienced machine operators, and do additional
research outside of this manual by reading "howto" books, trade magazines, or websites.

Eye injuries or respiratory problems can
occur while operating this tool. Wear personal protective equipment to reduce your
risk from these hazards.

Keep hair, clothing, and
jewelry away from moving parts at all times.
Entanglement can result
in death, amputation, or
severe crushing injuries!

To complete a typical operation, the operator
does the following:
1.

Examines workpiece to make sure it is suitable for turning. No extreme bows, knots, or
cracks should exist.

Prepares and trims workpiece to make it
roughly concentric.

Installs workpiece between centers, or attaches it to faceplate or chuck.

Adjusts tool rest to 1⁄8" above workpiece centerline, and sets minimum clearance between
the workpiece and lip of tool rest to 1⁄4".

Rotates workpiece by hand to verify that the
spindle and workpiece rotate freely throughout the range of motion.

Positions dust collection hood near work
piece to collect wood chips secure in place.

Ties back loose hair and clothing, and puts
on face shield and respirator. Takes all other
required safety precautions.

Starts lathe, adjusts lathe speed, and carefully begins turning operation, keeping chisel
against tool rest entire time it is cutting.

If you are not experienced with this type
of machine, WE STRONGLY RECOMMEND
that you seek additional training outside of
this manual. Read books/magazines or get
formal training before beginning any projects. Regardless of the content in this section, Grizzly Industrial will not be held liable
for accidents caused by lack of training.

Stock Inspection &
Requirements
Some workpieces are not safe to turn or may
require modification before they are safe to
turn. Before turning a workpiece, inspect all
workpieces for the following:
•

•

-18-

Workpiece Type:
This machine is intended for cutting natural
and man-made wood products, and some
plastics. Never attempt to cut any metal,
stone, or rubber workpiece; cutting these
materials can lead to machine damage or
severe injury.
Foreign Objects:
Nails, staples, dirt, rocks and other foreign
objects are often embedded in wood. While
cutting, these objects can become dislodged
and hit the operator, cause tool grab, or break
the turning tool, which might then fly apart.
Always visually inspect your workpiece for
these items. If they can't be removed, DO
NOT turn the workpiece.

•

Large/Loose Knots:
Loose knots can become dislodged during
the turning operation. Large knots can cause
a workpiece to completely break in half during turning and cause machine damage and
personal injury. Choose workpieces that do
not have large/loose knots.

•

Wet or "Green" Stock:
Cutting wood with a moisture content over
20% causes unnecessary wear on tooling
blades, increases the risk of tool grab, and
yields poor results.

•

Excessive Warping:
Workpieces with excessive bowing or twisting are unstable and unbalanced. Never turn
these workpieces at high speed, or instability
will be magnified and the workpiece can be
ejected from the lathe causing impact injures.
Only turn concentric workpieces!

Model T25920/T25926 (Mfd. Since 08/14)

Adjusting Spindle
Speeds
Your lathe has three speed ranges for maximum
turning options. These ranges are selected by
changing belt positions on the motor and spindle
pulleys (see Figure 14).
A = High Range
1600–3800 RPM

Always choose correct spindle speed for
your operation. Using wrong speed may lead
to workpiece breaking loose or being thrown
from lathe at a high rate of speed, causing
fatal or severe impact injuries.

(Viewed from Back of Headstock)

Figure 14. Speed ranges for each belt position.
High range (A) is best when turning a workpiece
where a clean finish is required and only light
cuts are made. Mid range (B) is a compromise
between the high and low ranges. Low range
(C), which has more torque, is best when turning a workpiece where a lot of material must be
removed and a rough finish does not matter. Use
the speed dial to adjust the spindle speed within
each range.
Refer to the speed recommendations chart in
Figure 15 to choose the appropriate RPM for your
operation. Then choose the speed range that will

Selecting Turning
Tools

•

Lathe tools come in a variety of shapes and sizes
and usually fall into five major categories.
•

Scrapers—Typically used where access for
other tools is limited, such as hollowing operations. This is a flat, double-ground tool that
comes in a variety of profiles (round nose,
spear point, square nose, etc.) to match
many different contours.

Gouges—Mainly used for rough cutting,
detail cutting, and cove profiles. Rough gouge
is a hollow, double-ground tool with a round
nose, and detail gouge is a hollow, doubleground tool with either a round or pointed
nose.
Figure 30. Example of a round nose scraper.
•

Parting Tools—Used for sizing and cutting off work. This is a flat tool with a sharp
pointed nose that may be single- or doubleground.

Figure 28. Example of a gouge.
•

Skew Chisel—A very versatile tool that can
be used for planing, squaring, V-cutting,
beading, and parting off. The skew chisel is
flat, double-ground with one side higher than
the other (usually at an angle of 20-40˚).

Figure 31. Example of a parting tool.
•

Specialty Tools—These are the unique,
special function tools to aid in hollowing, bowl
making, cutting profiles, etc. The Swan Neck
Hollowing Tool shown on Page 30 is a good
example of a specialty tool.

Figure 29. Example of a skew chisel.

Spindle Turning

Make center mark by using wood mallet and
tapping point of spur center into center of
workpiece on both ends.

Spindle turning is the operation performed when
a workpiece is mounted between the headstock
and the tailstock, as shown in Figure 32.

Using 1⁄4" drill bit, drill 1⁄4" deep hole at center
mark on end of workpiece to be mounted on
headstock spur center.

To help embed spur center into workpiece,
cut 1⁄8" deep saw kerfs in headstock end of
workpiece along diagonal lines marked in
Step 1.

If your workpiece is over 2" x 2", cut corners
off workpiece lengthwise to make turning
safer and easier (see Figure 34).

Figure 32. Typical spindle turning operation.
Workpiece
Center

Make sure the headstock and tailstock centers are properly aligned before beginning
any turning operation. Failure to observe
this warning could result in the workpiece
being thrown from the lathe, resulting in
serious personal injury.
To set up a spindle turning operation:
1.

Find center point of both ends of your
workpiece by drawing diagonal lines from
corner to corner across end of workpiece, as
shown in Figure 33.

-25-

With workpiece still attached, insert spur center into headstock spindle (refer to Installing/
Removing Headstock Center on Page 22
for additional instructions).
Note: Use the tool rest to support the opposite end of workpiece so that the workpiece
and spur center do not separate during
installation.

Spindle Turning Tips:
•

When turning the lathe ON, stand away from
the path of the spinning workpiece until the
spindle reaches full speed and you can verify
that the workpiece will not come loose.

•

Use the slowest speed when starting or stopping the lathe.

Install live center into tailstock quill and
tighten quill lock lever to lock quill in position
(refer to Page 22 for additional instructions).

•

Select the right speed for the size of workpiece
that you are turning (refer to Figure 15 on
Page 19).

Slide tailstock toward workpiece until point of
live center touches workpiece center mark,
then lock tailstock in this position.

•

Keep the turning tool on the tool rest the
ENTIRE time that it is in contact with the
workpiece.

10. Loosen quill lock lever and rotate tailstock
handwheel to push live center into workpiece
at least a 1⁄4".

•

Learn the correct techniques for each tool
you will use. If you are unsure about how to
use the lathe tools, read books or magazines
about lathe techniques, and seek training
from experienced and knowledgeable lathe
users.

Do not press workpiece too firmly with
tailstock or bearings will bind and overheat. Do not adjust tailstock too loosely or
workpiece will spin off lathe. Use good judgment and care, otherwise, serious personal
injury could result from workpiece being
ejected at high speeds.

Eye injuries or respiratory problems can
occur while operating this tool. Wear personal protective equipment to reduce your
risk from these hazards.

11. Properly adjust tool rest to the workpiece
(see Adjusting Tool Rest on Page 21).
12. Before beginning lathe operation, rotate
workpiece by hand to ensure that there is
safe clearance on all sides.

Keep lathe tool resting on tool rest ENTIRE
time that it is in contact with workpiece or
when preparing to make contact between
lathe tool and workpiece. Otherwise, spinning workpiece could force lathe tool out
of your hands or entangle your hands with
workpiece. Failure to heed this warning
could result in serious personal injury.

Model T25920/T25926 (Mfd. Since 08/14)

Faceplate Turning
Faceplate turning is when a workpiece is mounted
to the faceplate, which is then mounted to the
headstock spindle, as shown in Figure 36. This
type of turning is usually done with open-faced
workpieces like bowls or plates.

NOTICE

Only use screws with non-tapered heads
(see Figure 38) to attach the faceplate to
the workpiece. Screws with tapered heads
can split the faceplate or snap off during
operation.

Mounting Workpiece to Faceplate
1.

Mark workpiece center in same manner as
described in Spindle Turning (see Page 25).
Note: Cut off corners of workpiece to make it
as close to "round" as possible, as described
in Spindle Turning on Page 25.

Thread and secure faceplate onto headstock spindle (refer to Removing/Installing
Faceplate on Page 23 for faceplate mounting instructions).
— If wood screws cannot be placed in the
workpiece, the faceplate can be mounted to a backing block attached to the
workpiece (see Mounting Workpiece to
Backing Block on Page 28).

Center faceplate on workpiece and attach
with wood screws that do not have tapered
heads (see Figure 37).

-27-

Mounting Workpiece to Backing
Block
1.

Make backing block from a suitable size
piece of scrap wood.
Note: The faces of the backing block must be
flat and parallel to each other, or the uneven
surfaces will cause the workpiece to spin
eccentrically, causing unnecessary vibration
and runout. It is best to mount the backing
block to the faceplate and turn the other surface flat prior to mounting.

Locate and mark center of workpiece and
backing block.

Drill a 1⁄4" hole through center of backing
block.

Look through hole in backing block to line up
center with workpiece, then glue and clamp
backing block to workpiece.
Note: Allow the glue to cure according to
manufacturer instructions.

Follow Steps 1–3 in Mounting Workpiece
to Faceplate (see Page 27) to attach backing block to the faceplate.

Sanding/Finishing
After the turning operations are complete, the
workpiece can be sanded and finished before
removing it from the lathe, as shown in Figure 39.

Figure 39. Typical sanding operation.
Note: Whenever sanding or finishing, move the
tool rest holder out of the way to increase personal safety and gain adequate working room.

Tensioning &
Replacing Belt

Pulley

⁄2"

The drive belt stretches as the lathe is used.
Most of the stretching will occur during the first
16 hours, but may continue with further use. If the
lathe loses power while making a cut, the belt may
be slipping and need tensioning. If the belt shows
signs of excessive wear, or damage, replace it.

Replacing Brushes

Carefully remove brush from motor (see
Figure 56).

Your machine is equipped with a universal motor
that uses carbon brushes to transmit electrical current inside the motor. These brushes
are considered to be regular "wear items" or
"consumables" that will eventually need to be
replaced. The frequency of this replacement is
directly related to how much the motor is used
and how hard it is pushed.
Replace the carbon brushes when the motor no longer reaches full power, or when the brushes measure less than 1⁄4" long (new brushes are 5 ⁄ 8" long).
