conditions can create “kickback” and know
how to avoid them. Read the manual accompanying the machine thoroughly.
18. CHECK DAMAGED PARTS. Before fur-
ther use of the tool, a guard or other part
that is damaged should be carefully
checked to determine that it will operate
properly and perform its intended function.
Check for alignment of moving parts, binding of moving parts, breakage of parts,
mounting, and any other conditions that
may affect its operation. A guard or other
part that is damaged should be properly
repaired or replaced.
19. NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Do not
leave tool until it comes to a complete stop.
20. NEVER OPERATE A MACHINE WHEN
TIRED, OR UNDER THE INFLUENCE OF
DRUGS OR ALCOHOL. Full mental alert-
ness is required at all times when running a

110V Operation
SECTION 2: CIRCUIT REQUIREMENTS
A 15 amp dedicated circuit should be used with
this wood lathe. Always check to see if your current wires are capable of handling a 4 amp load.
If you are unsure, consult the advice of a qualified
electrician.
If you find it necessary to use an extension cord
with the Model G5979, make sure the cord is
rated Hard Service (grade S) or better. Refer to
the chart in the standard safety instructions to
determine the minimum gauge for the extension
cord. The extension cord must also contain a
ground wire and plug pin. Always repair or replace
extension cords when they become worn or damaged.
Extension Cords
Grounding
This equipment must be
grounded. Verify that any
existing electrical outlet
and circuit you intend to
plug into is actually
grounded. Under no circumstances should the
grounding pin from any
three-pronged plug be
removed. Serious injury
may occur.
In the event of an electrical short, grounding
reduces the risk of electric shock by providing
electric current a path of least resistance. This
tool is equipped with a power cord having an
equipment-grounding conductor as shown in
Figure 1B. The outlet must be properly installed
and grounded in accordance with all local codes
and ordinances.
The Model G5979 is wired for 110V operation
only. The
1
⁄2 H.P. motor will safely draw 4 amps at
110V. If you operate this machine on any circuit
that is already close to its capacity, it might blow
a fuse or trip a circuit breaker. However, if an
unusual load does not exist and a power failure
still occurs, contact a qualified electrician or our
service department.

Clean Up
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.
Do not smoke while using
solvents. A risk of explosion or fire exists and may
result in serious personal
injury.
Do not use gasoline or
other petroleum-based
solvents. 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 if this
warning is ignored.
Many of the solvents
commonly used to clean
machinery can be toxic
when inhaled or ingested. Always work in wellventilated 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 environmental hazards.
Site Considerations
FLOOR LOAD
Your Model G5979 represents a moderate weight
load in a small footprint. Most commercial or
home shop floors should be sufficient to carry the
weight of the Model G5979. If you question the
strength of your floor, you can opt to reinforce it.
Ensure that the stand or bench you use with the
Model G5979 is capable of supporting the
machine.
WORKING CLEARANCES
Working clearances can be thought of as the distances between machines and obstacles that
allow safe operation of every machine without limitation. 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 efficient material handling. Be sure to allow yourself
sufficient room to safely run your machines in any
foreseeable operation and keep dust collection
hoses off the floor and out of the way.
LIGHTING AND OUTLETS
Lighting should be bright enough to eliminate
shadows 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.
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, adjusting or operating equipment.

Lathe To Stand
Figure 5. Attaching lathe unit to stand.
Do not attempt to lift the
lathe onto the stand by
yourself. Seek the assistance of another person.
We highly recommend mounting your Model
G5979 to the floor. Doing so will eliminate any
possibility of the lathe becoming unbalanced and
tipping over. The lathe will also produced better
results because there will be less vibration from
the machine. To mount the lathe to the floor:
Wooden Floor:
Use
1
⁄4" lag screws with flat washers. Be certain
the floor is stable and level. Drill pilot holes into
the floor and be careful not to tighten the lag bolts
too much or the hole may become stripped out.
Concrete Floor:
Mounting the lathe to a concrete floor involves the
use of stud anchors or some other similar fastener. Once the location is selected, drill the anchor
holes into the concrete floor using a hammer drill
and masonry bit. Be sure to follow the directions
of the anchoring system you have chosen.
Once the lathe is secured to the floor, check to
make sure it is still level and all the mounting bolts
are secure. Shim if needed.

keep hair pulled back.
The headstock has 5 preset positions: 0° for general spindle turning; 60°, 90° and 120° when doing
faceplate turnings where the workpiece extends
below the level of the lathe/extension bed; and
180° when doing faceplate turning where the
workpiece edge does not extend below the edge
of the lathe/extension bed. To set the headstock
to the desired degree:
1. Loosen the lock handle by turning counter-
clockwise one full revolution.
2. Pull out on the headstock release knob and
rotate the headstock clockwise to the desired
setting. The headstock will be fixed into position when it clicks into one of the 5 preset
positions.
3. Tighten the lock handle that was loosened in
the first step. Do not attempt to lock the
headstock into a position other than the 5
presets.
Headstock
Figure 12. Adjusting headstock.
The tailstock can be moved along the length of
the lathe bed. The tailstock barrel holds the live
center, which can be adjusted up to 2
1
⁄2" from the
tailstock housing. To adjust the tailstock and tailstock spindle:
1. Loosen the tailstock lock handle by lowering
it and slide the tailstock to the desired position along the lathe bed. Retighten the tailstock lock handle by lifting it. The lock handle
mechanism can be adjusted by tightening or
loosening the large hex nut under the tailstock.
2. To adjust the tailstock barrel, loosen the spin-
dle lock handle.
3. Rotate the tailstock spindle handwheel until
the desired position is achieved. Retighten
the tailstock spindle lock handle.
4. To remove the live center from the tailstock
spindle, use the push-out rod inserted
through the hollow center of the tailstock
spindle.

SECTION 5: OPERATIONS
Once assembly is complete and adjustments are
done to your satisfaction, you are ready to test run
the machine.
Press the START button. Make sure that your finger is poised on the STOP button, just in case
there is a problem. The lathe should run smoothly, with little or no vibration or rubbing noises.
Strange or unnatural noises should be investigated and corrected before operating the machine
further.
If you cannot easily locate the source of an
unusual noise or vibration, contact our service
department for help.
Test Run
Wear a face shield during the test run and
operation of this wood
working lathe. Failure to
do so could result in
serious injury.
Keep loose clothing
rolled up and out of the
way of machinery and
keep hair pulled back.
Speed Selector
The variable speed selector allows the adjustment of the spindle R.P.M. The lathe should only
be turned ON when the speed is set at the lowest
R.P.M. The lathe must be ON to adjust the speed;
therefore, be sure to set the speed to the lowest
R.P.M. before turning OFF the machine.
Figure 16. Adjusting spindle speed.
Remember to choose the correct speed for
your particular turning project. As a general rule, the larger the workpiece diameter,
the slower the speed. Always start and stop
at the slowest speed.
The speed control lever can be turned to one of
ten fixed speeds. To set the speed:
1. Turn the lathe ON. Make sure that your finger
is poised on the STOP button, just in case
there is a problem. The lathe should run
smoothly, with little or no vibration or rubbing
noises. Strange or unnatural noises should
be investigated and corrected before operating the machine further. If you cannot easily
locate the source of an unusual noise or
vibration, contact our service department for
help.
2. Pull back on the lever handle and rotate to
the next higher speed as shown in
Figure 16
.
3. Turn the lever handle clockwise along the
index plate to increase the speed and counterclockwise to decrease the speed.
4. Remember to turn the lever handle to the
slowest R.P.M. before turning off the
machine.

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 intersection is the center of the work. Find the center
of a round workpiece by using a center finder
instrument.
2. When turning stock with a diameter greater
than 2", remove the corner length edges
shown in
Figure 17.
3. Line up the center of the spur center with the
center mark on the end of the workpiece.
While supporting the workpiece, slide the tailstock close to the end of the workpiece and
lock it into place.
4. Line up the live center with the center mark
on the other end of the workpiece. Turn the
handwheel to press the point of the live center into the workpiece.
5. Lock the tailstock in place.
Spindle Turning
Figure 17. Cross-section of turning stock.
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.

If measurement D" is greater
than 2", cut off the corners of

1. Locate the center point of the workpiece by
carefully drawing diagonal lines from corner
to corner. The point of intersection is the center of the work. Find the center of round workpiece by using a center finder instrument.
2. Using 4 wood screws, attach the workpiece
as close to the center of the faceplate as possible. Make sure that the wood screws will
not interfere with the lathe chisels or intended cuts.
3. Adjust the headstock to the desired position
for the turning operation that you will be performing.
4. Attach the faceplate/workpiece assembly to
the headstock spindle using two wrenches.
Faceplate turning projects fall into two categories:
those that extend below the level of the
lathe/extension bed and those that do not. If your
project will rotate below the level of the
lathe/extension bed, you will need to rotate the
headstock to the 60° or 90° positions (discussed
further in Adjustments section). But if your pro-
ject does not extend below the lathe/extension
bed, it is safest to rotate the headstock 180° so
the project will rotate over the extension bed. This
allows the operator to stand directly in front of the
project and allows use of the tool rest without the
extension arm, thus, eliminating undue flexing of
the tool rest.
Faceplate Turning
Figure 19. Faceplate turning large projects.
Adjust the tool rest as close to the workpiece as
possible without actually coming into contact with
the workpiece. Test by hand-turning the workpiece 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 21.

do so could result in
serious injury.

SECTION 7: MAINTENANCE
Lubrication
V-Belt
All bearings are shielded and permanently lubricated. Simply leave them alone until they need to
be replaced. Do not lubricate them.
The end of the motor shaft has a lube fitting that
requires periodic lubrication. It is very important
not to over lube this fitting; otherwise, dirt and
debris will collect on the motor shaft, causing premature failure of the pulley mechanism. We recommend using a few shots of light spindle oil.
Inspect regularly for tension and wear. Check pulleys to ensure that they are properly aligned. See
pulley/V-belt sections for proper tension and pulley alignment procedures.
Regular periodic maintenance on your Model
G5979 will ensure its optimum performance.
Make a habit of inspecting your machine 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 V-belt.
5. Any other condition that could hamper the
safe operation of this machine.
General
Dust/Chip Removal
Saw dust and wood chips allowed to sit on cast
iron surfaces can trap moisture and cause rust.
Regularly wipe or blow sawdust and chip buildup
of of the lathe unit. This will help reduce the
chance of rust.
Rust
The nonpainted surfaces on the Model G5979
should be protected against rust and pitting.
Wiping the machine clean after every use ensures
that wood dust will not trap moisture against bare
metal surfaces.
Disconnect power to the
machine when performing any maintenance,
assembly or adjustments. Failure to do this
may result in serious
personal injury.
Wear safety glasses
during the entire maintenance process. Failure
to comply may result in
serious personal injury.
Keep loose clothing
rolled up and out of the
way of machinery and
keep hair pulled back.
