WARNING
Some dust created by power sanding, sawing, grind-
ing, drilling, and other construction activities contains
chemicals known to the State of California to cause
cancer, birth defects or other reproductive harm. Some
examples of these chemicals are:
• Lead from lead-based paints.
• Crystalline silica from bricks, cement, and
other masonry products.
• Arsenic and chromium from chemically treated
lumber.
Your risk from these exposures varies, depending on
how often you do this type of work. To reduce your
exposure to these chemicals: work in a well ventilated
area, and work with approved safety equipment, such
as those dust masks that are specially designed to fil-
ter out microscopic particles.

Additional Safety Instructions for Lathe/Mills
No list of safety guidelines can be complete.
Every shop environment is different. Always
consider safety first, as it applies to your
individual working conditions. Use this and
other machinery with caution and respect.
Failure to do so could result in serious per-
sonal injury, damage to equipment, or poor
work results.
Like all machines there is danger associ-
ated with the Model G9729. Accidents are
frequently caused by lack of familiarity or
failure to pay attention. Use this machine
with respect and caution to lessen the pos-
sibility of operator injury. If normal safety
precautions are overlooked or ignored, seri-
ous personal injury may occur.
1. AVOID CRASHES. Make sure no part of
tool, tool holder, compound or cross slide,
or carriage will come into contact with the
chuck during operation.
2. PRE-START. Before starting the machine
be certain the workpiece has been properly
engaged in the chuck and tailstock center
(if in use) and that there is adequate clear-
ance for full rotation.
3. HOLDING TOOLS. Adjust tool holder to
provide proper support for the turning tool
you will be using. Test tool holder clearance
by rotating workpiece by hand before turn-
ing lathe ON.
4. SPINDLE SPEEDS. Select the spindle
speed which is appropriate for the type of
work and material. Allow the lathe/mill to
gain its full speed before beginning a cut.
5. FEED RATE CHANGES. Never change
feed rate or spindle speeds while the lathe
is in motion.
6. SPINDLE DIRECTION CHANGES. Never
reverse motor direction while the lathe/mill
is in motion.
7. STOPPING SPINDLE. DO NOT stop lathe
using your hand against the workpiece or
chuck.
8. BE ATTENTIVE. DO NOT leave lathe/mill
running unattended for any reason.
9. MACHINE CARE AND MAINTENANCE.
Never operate the lathe/mIll with dam-
aged or worn parts. Maintain your lathe/mill
in proper working condition. Perform rou-
tine inspections and maintenance promptly
when called for. Put away adjustment tools
after use.
10. DISCONNECT POWER. Make sure lathe/
mill is turned OFF, disconnected from its
power source and all moving parts have
come to a complete stop before starting
any inspection, adjustment, or maintenance
procedure.
11. AVOIDING ENTANGLEMENT. Keep loose
clothing articles such as sleeves, belts or
jewelry items away from the lathe and drill
spindles.
12. CUTTING TOOLS. Always use the proper
cutting tools for the material you are turning,
make certain they are sharp and that they
are held firmly in the tool holder.
13. SAFE CHUCK HANDLING. Always place
a board or piece of plywood across the
bedway when removing or installing chucks
to avoid the possibility of a finger pinch
occurring between a loose chuck and the
edges of the bedway.
14. CLEAN-UP. DO NOT clear chips by hand.
Use a brush, and never clear chips while
the lathe is turning.

operators. The workbench the machine rests on
should be strong and stable enough to hold the
weight of the machine and the workpiece.
Working Clearances
Consider existing and anticipated needs, size of
material to be processed through each machine,
and space for auxiliary stands, work tables or
other machinery when establishing a location for
your lathe/mill combo (see Figure 4).
Unsupervised children and
visitors inside your shop
could cause serious per-
sonal injury to themselves.
Lock all entrances to the
shop when you are away and
DO NOT allow unsupervised
children or visitors in your
shop at any time!
The unpainted surfaces are coated with a waxy
oil to protect them from corrosion during ship-
ment. Remove this protective coating with a sol-
vent cleaner or citrus-based degreaser such as
Grizzly’s G7895 Degreaser. To clean thoroughly,
some parts may need to be removed. For opti-
mum performance from your machine, make
sure you clean all moving parts or sliding
contact surfaces that are coated. Avoid chlo-
rine-based solvents, such as acetone or brake
parts cleaner, as they may damage painted sur-
faces should they come in contact. Always follow
the manufacturer’s instructions when using any
type of cleaning product.
Site ConsiderationsClean Up
Gasoline and petroleum
products have low flash
points and could cause
an explosion or fire if
used to clean machinery.
DO NOT use gasoline or
petroleum products to
clean the machinery.
Many of the solvents
commonly used to clean
machinery can be toxic
when inhaled or ingest-
ed. Lack of ventilation
while using these sol-
vents could cause seri-
ous personal health risks
or fire. Take precautions
from this hazard by only
using cleaning solvents
in a well ventilated area.

Moving & Placing
Base Unit
The Model G9729 is a
heavy machine, 525
lbs. DO NOT move the
machine by yourself –
you will need assistance
and power equipment.
Serious personal injury
may occur if safe mov-
ing methods are not fol-
lowed.
Wear safety glasses dur-
ing the entire setup pro-
cess!
Figure 5. Use lifting straps, bars and power
equipment to lift machine.
The Model G9729 requires the use of lifting
equipment such as a fork lift, engine hoist or
boom crane. DO NOT lift the machine by hand.
Holes are provided in the edge of the lathe bed
for inserting 3⁄4" steel rods for lifting (see Figure
5). Used in conjunction with lifting straps and fol-
lowing safe lifting procedures as detailed by the
manufacturers of these lifting devices, the lathe/
mill can be safely lifted off the pallet and placed
on a sturdy work bench.
Practice safe lifting:
• Position the tailstock and apron to the far
right on the lathe bed. (Opposite of the head-
stock.)
• Make sure the steel rods for lifting extend at
least 8" on each side of the lathe bed.
• DO NOT lift the machine from any other
points than the lifting holes provided.
• Use lifting equipment such as a fork lift,
engine hoist or crane to move or lift the lathe/
mill. Never use only human power to lift the
machine.

Handwheels
Hand Crank
Figure 7. Attach handles to handwheels.
Figure 6. The key is engaged with the hand
crank.
The apron and cross slide handwheel handles
must be installed. A screwdriver is supplied for
this job. Locate the threaded holes on each hand
wheel and attach the handles (see Figure 7).
The hand crank for the longitudinal manual feed
must be installed.
To install the hand crank:
1. The end of the leadscrew has a washer and
screw attached. Remove these.
2. The hand crank has a key slot on one side
as shown in Figure 6. Slide the hand crank
onto the end of the leadscrew, key slot first.
3. Thread the screw through the washer and
into the end of the leadscrew.
4. To use the hand crank, push it in towards the
leadscrew so the key way and key engage.
Turn the hand crank while keeping pressure
applied. When released, the hand crank will
withdraw from the leadscrew and will no lon-
ger be engaged.

The Model G9729 Lathe/Mill comes equipped
with a steady rest and follow rest. These are used
to support smaller stock while turning, drilling or
boring. They are installed at the factory for ship-
ping purposes and should be removed at this
time. The steady rest has a single clamp bolt that
once removed, allows the clamp shoe to come
out the side (Figure 8) and the main body to be
lifted off of the lathe bed.
To remove the follow rest, simply remove the two
cap screws at its base. We recommend threading
the screws back into the mounting holes to keep
the holes clear of debris and to make sure they
do not become misplaced.

Now that the lathe/mill is set up and you have
read the safety guidelines, it’s time to give each
motor a test run.
The purpose of the test run is to make sure the
lathe/mill is wired correctly and the motors are
working properly before proceeding with addi-
tional set up. Check to make sure that auto feeds
are not engaged, the chucks are secure in the
spindles, and there are no loose parts around
the spindles. Set the lathe/mill to the slowest
RPM before the test run. Refer to Control Panel
on Page 19, Lathe Speeds on Page 34, Mill
Speeds on Page 44, and Lubrication on Page
51 before doing the test run.
The lathe and mill motors will be tested inde-
pendently. Before starting the lathe/mill:
1. Make sure the machine is properly ground-
ed, the power switch is turned OFF, and
both reversing switches are set to the middle
position.
2. Inspect the machine to ensure that all hand
tools are out of the way, guards are in place
and nothing is impeding the movement of
either chuck. Check this by rotating each by
hand.
3. Rotate the EMERGENCY STOP button in
the direction of the arrows on the button and
allow it to pop out.
4. Push the START button on the control panel.
While keeping your hand on the reversing
switch for the lathe, turn it to the FORWARD
position. The lathe should run smoothly with
little or no vibration or rubbing noises when it
starts. Strange or unnatural noises should be
investigated and corrected before operating
the machine further.
5. If the lathe/mill is running correctly, turn the
reversing switch to the OFF position, wait for
the machine to come to a complete stop.
Keep clothing rolled
up and out of the way
of machinery and keep
hair pulled back.
Wear safety glasses dur-
ing all operations on the
lathe/mill.Failure to com-
ply may result in serious
personal injury.
Disconnect power to the
machine when perform-
ing any adjustments or
maintenance. Failure to
do this may result in seri-
ous personal injury.
Test Run
Inspect your machine for
loose nuts and bolts, and
ensure no tools are left
in or around the machine
before connecting power.
Failure to do this may
result in personal injury.
