Safety Instructions For Power Tools
9. USE PROPER EXTENSION CORD. Make
sure your extension cord is in good condi-
tion. Conductor size should be in accor-
dance with the chart below. The amperage
rating should be listed on the motor or tool
nameplate. An undersized cord will cause
a drop in line voltage resulting in loss of
power and overheating. Your extension
cord must also contain a ground wire and
plug pin. Always repair or replace exten-
sion cords if they become damaged.
16. REDUCE THE RISK OF UNINTENTION-
AL STARTING. On machines with mag-
netic contact starting switches there is a
risk of starting if the machine is bumped or
jarred. Always disconnect from power
source before adjusting or servicing. Make
sure switch is in OFF position before recon-
necting.
17. MANY WOODWORKING TOOLS CAN
“KICKBACK” THE WORKPIECE toward
the operator if not handled properly. Know
what conditions can create “kickback” and
know how to avoid them. Read the manual
accompanying the machine thoroughly.

ground wire and plug pin. Always repair or replace
extension cords when they become worn or dam-
aged.
Grounding
In the event of an electrical short, grounding
reduces the risk of electric shock by providing a
path of least resistance to disperse electric cur-
rent. This tool is equipped with a power cord hav-
ing an equipment-grounding conductor. See
Figure 1. The outlet must be properly installed
and grounded in accordance with all local codes
and ordinances.

Unpacking
Piece Inventory
This wood lathe is shipped from the manufacturer
in a carefully packed carton. If you discover the
machine is damaged after you’ve signed for deliv-
ery, and the truck and driver are gone, you will
need to file a freight claim with the carrier. Save
the containers and all packing materials for possi-
ble inspection by the carrier or its agent. Without
the packing materials, filing a freight claim can be
difficult. If you need assistance determining
whether you need to file a freight claim, or with the
procedure to file one, please contact our
Customer Service.
After all the parts have been removed from the
carton, you should have:
• Lathe Assembly
• Stand Assembly
• Tool Rest
• Tailstock
• Live Center
• #1 M.T. Spur Center
• Hardware Accessories
In the event that any non-proprietary parts are
missing (e.g. a nut or a washer), we would be glad
to replace them, or, for the sake of expediency,
replacements can be obtained at your local hard-
ware store.
When you are completely satisfied with the condi-
tion of your shipment, you should inventory its
parts.
NOTICE

Clean Up
Site Considerations
The unpainted surfaces are coated with a waxy oil
to protect them from corrosion during shipment.
Remove this protective coating with a solvent
cleaner or citrus-based degreaser such as
Grizzly’s G7895 Degreaser. Avoid chlorine-based
solvents as they may damage painted surfaces
should they come in contact. Always follow the
usage instructions on the product you choose for
clean up.
BENCH LOAD
Your Model G8690 represents a moderately large
weight load in a small footprint. Ensure that your
workbench is sturdy enough to carry the weight of
the Model G8690. If you question the strength of
your workbench, you can opt to reinforce it.
WORKING CLEARANCES
Working clearances can be thought of as the dis-
tances between machines and obstacles that
allow safe operation of every machine without lim-
itation. Consider existing and anticipated machine
needs, size of material to be processed through
each machine, and space for auxiliary stands
and/or work tables. Also consider the relative
position of each machine to one another for effi-
cient material handling. Be sure to allow yourself
sufficient room to safely run your machines in any
foreseeable operation.
Do not use gasoline or
other petroleum-based
solvents to clean with.
They have low flash
points which make them
extremely flammable. A
risk of explosion and
burning exists if these
products are used.
Serious personal injury
may occur.
LIGHTING AND OUTLETS
Lighting should be bright enough to eliminate
shadow and prevent eye strain. Electrical circuits
should be dedicated or large enough to handle
combined motor amp loads. Outlets should be
located near each machine so power or extension
cords are not obstructing high-traffic areas. Be
sure to observe local electrical codes for proper
installation of new lighting, outlets, or circuits.
Many of the solvents commonly used to
clean machinery can be toxic when inhaled
or ingested. Always work in well-ventilated
areas far from potential ignition sources
when dealing with solvents. Use care when
disposing of waste rags and towels to be
sure they do not create fire or environmen-
tal hazards. Keep children and animals
safely away when cleaning and assembling
this machine.
Make your shop “child
safe.” Ensure that your
workplace is inaccessible
to youngsters by closing
and locking all entrances
when you are away. Never
allow visitors in your shop
when assembling, adjust-
ing or operating equip-
ment.
Do not smoke while using
solvents. A risk of explo-
sion or fire exists and may
result in serious personal
injury.

The tailstock rests on the guide rails and is held in
place by the tailstock bracket using a double end
screw (M12-1.75 x 65), washer and handle. The
tailstock can be adjusted along the length of the
guide rails to accommodate various lengths of
wood stock. There are two ways to adjust the tail-
stock. The handle located under the lathe bed can
be loosened, allowing the tailstock to slide up and
down the length of the guide rails; or the hand
wheel can be loosened, allowing the threaded
spindle to move back and forth in the tailstock for
fine adjustment. See Figure 5.

Spur Center
Faceplate
The Model G8690 is supplied with a #1 Morse
Taper spur center for use when spindle turning.
The spur center is used in conjunction with the
tailstock live center. Install the spur center by
inserting it into the hole in the headstock spindle
end. To remove the spur center from the head-
stock, insert a pin into the spindle hole and turn
the hex nut counterclockwise with a wrench until
the spur center is ejected. See Figure 5A.
The faceplate is used for turning plates and
bowls. To install the faceplate, remove the spur
center. Insert a pin in the spindle shaft to hold the
spindle, and thread the faceplate onto the spindle
threads as seen in Figure 6. Tighten securely
with your fingers, and use the mounting holes on
the faceplate to attach wood stock with wood
screws.
We recommend cleaning the spur center
taper with mineral spirits. Refer to the safe-
ty warnings on the container of the mineral
spirits. Failure to clean the mating surfaces
may result in separation, and an unsafe
condition. Separation is usually a result of
oil or grease on the taper.

SECTION 5: OPERATIONS
Spindle Turning
Test Run
To mount a workpiece between centers:
1. Locate the center point on both ends of the
workpiece by carefully drawing diagonal lines
from corner to corner. The point of intersec-
tion is the center of the work. Find the center
of round wood stock by using a center finder
instrument.
Keep loose clothing
rolled up and out of the
way of machinery and
keep hair pulled back.
2. When turning stock with a diameter greater
than 2", remove the corner length edges with
a hand plane or similar operation as shown in
Figure 6A.
Wear a face shield dur-
ing the test run and
operation of this wood
working lathe. Failure to
do so could result in
serious injury.
Wood Stock
Once assembly is complete and adjustments are
done to your satisfaction, you are ready to test run
the machine.
D"
Press the START button. Make sure that your fin-
ger is poised on the STOP button, just in case
there is a problem. The lathe should run smooth-
ly, with little or no vibration or rubbing noises.
Strange or unnatural noises should be investigat-
ed and corrected before operating the machine
further.
If measurement D" is greater
than 2", cut off the corners of
the wood stock.
Figure 6A. Cross-section of turning stock.
If you cannot easily locate the source of an
unusual noise or vibration, contact our service
department for help.
3. Hold the spindle vertically and support it on a
solid surface. Line up the spur center with the
center of the workpiece. Drive the spur cen-
ter into the stock about 1⁄4" using a dead blow
hammer. Be careful not to split the work-
piece. See
Wood with splits along
Figure 6B.
Make sure the live center in the tailstock
lines up with the spur center in the head-
stock before turning anything between the
centers. Failure to observe this step could
result in the workpiece being thrown from
the lathe. Serious personal injury could
occur if care is not taken.
the grain may fly off during the operation.
With dense wood, drill a hole at the centers
and score lines with a saw blade for the spur.

Speed Selector
The variable speed selector allows the adjust-
ment of the spindle R.P.M. Before turning the
lathe on, make sure the speed selector knob is set
at the lowest R.P.M. (turn counterclockwise). See
Figure 7.
1/4"
Once the lathe is turned on, slowly increase the
R.P.M. of the lathe by turning the speed selector
knob clockwise. Make sure that your finger is
poised on the STOP button, just in case there’s a
problem. The lathe should run smoothly, with little
or no vibration or rubbing noises. Strange or
unnatural noises should be investigated and cor-
rected before operating the machine further.
Figure 6B. Spur center set into wood stock.
4. Once the spur center is firmly attached to the
workpiece, insert the spur center (with the
attached workpiece) into the headstock spin-
dle. Be certain the hex nut is threaded onto
the spindle before tapping the spur center in.
If you cannot easily locate the source of an
unusual noise or vibration, contact our service
department for help.
5. While supporting the workpiece, slide the tail-
stock close to the end of the workpiece and
lock it into place.
Remember to choose the correct speed for
your particular turning project. As a gener-
al rule, the larger the workpiece diameter,
the slower the speed. Always start at the
slowest speed.
6. Line up the live center with the workpiece
center. Turn the handwheel to press the point
of the live center into the workpiece.
7. Lock the tailstock in place.
Do not press too firmly or the bearings will
bind and overheat. Likewise, do not adjust
too loosely or the workpiece will spin off
the lathe. Use good judgement. Serious
personal injury could result if care is not
taken.

Tool Rest
Adjust the tool rest as close to the workpiece as
possible without actually coming into contact with
the workpiece. Test by hand-turning the work-
piece before turning the lathe on. Ensure that the
lathe chisel is fully supported by the tool rest.
Support the lathe chisel on the tool rest with one
hand, while the other hand controls the chisel.
See Figure 8.

SECTION 7: MAINTENANCE
Some woodworkers recommend using automo-
General
tive paste wax on exposed steel and cast iron sur-
faces. The wax provides a layer of protection.
Avoid waxes that contain silicone or other syn-
thetic ingredients. These materials can find their
way into lumber that’s being worked, and can
make staining and finishing difficult. If you use

personal injury.
paste wax, make sure that it’s 100% Carnauba
wax.
Lubrication
Keep loose clothing
rolled up and out of the
way of machinery and
keep hair pulled back.
Since all bearings are shielded and permanently
lubricated, simply leave them alone until they
need to be replaced. Do not lubricate them.
Wear safety glasses dur-
ing the entire mainte-
nance process. Failure
to comply may result in
serious personal injury.
Regular periodic maintenance on your Model
G8690 will ensure its optimum performance.
Make a habit of inspecting your lathe each time
you use it. Check for the following conditions and
repair or replace when necessary:
1. Loose mounting bolts.
2. Worn switch.
3. Worn or damaged cords and plugs.
4. Damaged cog tooth belt.
The non-painted surfaces on the Model G8690
should be protected against rust and pitting.
Wiping the lathe clean after every use ensures
that wood dust isn’t allowed to trap moisture
against bare metal surfaces.

of this tool will void the warranty. If you are
confused about any aspect of this machine,
DO NOT use it until you have answered all
your questions. Serious personal injury
may occur.
We have included some important safety mea-
sures that are essential to this machine’s opera-
tion. While most safety measures are generally
universal, Grizzly reminds you that each work-
shop is different and safety rules should be con-
sidered as they apply to your specific situation.
Operating this equipment creates the poten-
tial for flying debris to cause eye injury.
Always wear safety glasses or goggles
when operating equipment. Everyday glass-
es or reading glasses only have impact
resistant lenses, they are not safety glasses.
Be certain the safety glasses you wear meet
the appropriate standards of the American
National Standards Institute (ANSI).
Like all power tools, there is danger asso-
ciated with the Model G8690. Accidents are
frequently caused by lack of familiarity or
failure to pay attention. Use this tool with
respect and caution to lessen the possibil-
ity of operator injury. If normal safety pre-
cautions are overlooked or ignored, seri-
ous personal injury may occur.
