Model G0602/G0752 (Mfg. Since 11/12) -3-
INTRODUCTION
The metal lathe is used to remove material from
a rotating workpiece, which is held in place on
the spindle with a chuck or faceplate. The cutting
tool is mounted on the carriage or tailstock and
moved against the spinning workpiece to perform
the cut.
Typical metal lathe cutting operations include fac-
ing, turning, parting, drilling, reaming, grooving,
knurling, and threading. There are a wide variety
of tools and workpiece holding devices available
for each of these operations.
Models G0602 and G0752 both require setting
gearbox dial positions and positioning V-belts to
select the spindle speed. However, the Model
G0752 features an electronic variable-speed con-
trol and digital RPM display that make it possible
to select speeds within the selected range while
the machine is running.

NOTICE
Safety Instructions for Machinery
SECTION 1: SAFETY

Model G0602/G0752 (Mfg. Since 11/12) -11-
WEARING PROPER APPAREL. Do not wear
clothing, apparel or jewelry that can become
entangled in moving parts. Always tie back or
cover long hair. Wear non-slip footwear to avoid
accidental slips, which could cause loss of work-
piece control.
HAZARDOUS DUST. Dust created while using
machinery may cause cancer, birth defects, or
long-term respiratory damage. Be aware of dust
hazards associated with each workpiece material,
and always wear a NIOSH-approved respirator to
reduce your risk.
HEARING PROTECTION. Always wear hear-
ing protection when operating or observing loud
machinery. Extended exposure to this noise
without hearing protection can cause permanent
hearing loss.
REMOVE ADJUSTING TOOLS. Tools left on
machinery can become dangerous projectiles
upon startup. Never leave chuck keys, wrenches,
or any other tools on machine. Always verify
removal before starting!
USE CORRECT TOOL FOR THE JOB. Only use
this tool for its intended purpose—do not force
it or an attachment to do a job for which it was
not designed. Never make unapproved modifica-
tions—modifying tool or using it differently than
intended may result in malfunction or mechanical
failure that can lead to personal injury or death!
AWKWARD POSITIONS. Keep proper footing
and balance at all times when operating machine.
Do not overreach! Avoid awkward hand positions
that make workpiece control difficult or increase
the risk of accidental injury.
CHILDREN & BYSTANDERS. Keep children and
bystanders at a safe distance from the work area.
Stop using machine if they become a distraction.
GUARDS & COVERS. Guards and covers reduce
accidental contact with moving parts or flying
debris. Make sure they are properly installed,
undamaged, and working correctly.
FORCING MACHINERY. Do not force machine.
It will do the job safer and better at the rate for
which it was designed.
NEVER STAND ON MACHINE. Serious injury
may occur if machine is tipped or if the cutting
tool is unintentionally contacted.
STABLE MACHINE. Unexpected movement dur-
ing operation greatly increases risk of injury or
loss of control. Before starting, verify machine is
stable and mobile base (if used) is locked.
USE RECOMMENDED ACCESSORIES. Consult
this owner’s manual or the manufacturer for rec-
ommended accessories. Using improper acces-
sories will increase the risk of serious injury.
UNATTENDED OPERATION. To reduce the
risk of accidental injury, turn machine OFF and
ensure all moving parts completely stop before
walking away. Never leave machine running
while unattended.
MAINTAIN WITH CARE. Follow all maintenance
instructions and lubrication schedules to keep
machine in good working condition. A machine
that is improperly maintained could malfunction,
leading to serious personal injury or death.
CHECK DAMAGED PARTS. Regularly inspect
machine for any condition that may affect safe
operation. Immediately repair or replace damaged
or mis-adjusted parts before operating machine.
MAINTAIN POWER CORDS. When disconnect-
ing cord-connected machines from power, grab
and pull the plug—NOT the cord. Pulling the cord
may damage the wires inside. Do not handle
cord/plug with wet hands. Avoid cord damage by
keeping it away from heated surfaces, high traffic
areas, harsh chemicals, and wet/damp locations.
EXPERIENCING DIFFICULTIES. If at any time
you experience difficulties performing the intend-
ed operation, stop using the machine! Contact our
Technical Support at [phone].

Additional Safety for Metal Lathes
SPEED RATES. Operating the lathe at the wrong
speed can cause nearby parts to break or the
workpiece to come loose, which will result in dan-
gerous projectiles that could cause severe impact
injuries. Large or non-concentric workpieces must
be turned at slow speeds. Always use the appro-
priate feed and speed rates.
CHUCK KEY SAFETY. A chuck key left in the
chuck can become a deadly projectile when the
spindle is started. Always remove the chuck key
after using it. Develop a habit of not taking your
hand off of a chuck key unless it is away from the
machine.
SAFE CLEARANCES. Workpieces that crash
into other components on the lathe may throw
dangerous projectiles in all directions, leading to
impact injury and damaged equipment. Before
starting the spindle, make sure the workpiece has
adequate clearance by hand-rotating it through its
entire range of motion. Also, check the tool and
tool post clearance, chuck clearance, and saddle
clearance.
LONG STOCK SAFETY. Long stock can whip
violently if not properly supported, causing serious
impact injury and damage to the lathe. Reduce this
risk by supporting any stock that extends from the
chuck/headstock more than three times its own
diameter. Always turn long stock at slow speeds.
CRASHES. Aggressively driving the cutting tool or
other lathe components into the chuck may cause
an explosion of metal fragments, which can result
in severe impact injuries and major damage to
the lathe. Reduce this risk by releasing automatic
feeds after use, not leaving lathe unattended, and
checking clearances before starting the lathe.
Make sure no part of the tool, tool holder, com-
pound rest, cross slide, or carriage will contact the
chuck during operation.
SECURING WORKPIECE. An improperly secured
workpiece can fly off the lathe spindle with deadly
force, which can result in a severe impact injury.
Make sure the workpiece is properly secured in the
chuck or faceplate before starting the lathe.
CHUCKS. Chucks are very heavy and difficult to
grasp, which can lead to crushed fingers or hands
if mishandled. Get assistance when handling
chucks to reduce this risk. Protect your hands and
the precision-ground ways by using a chuck cradle
or piece of plywood over the ways of the lathe
when servicing chucks. Use lifting devices when
necessary.
CLEARING CHIPS. Metal chips can easily cut
bare skin—even through a piece of cloth. Avoid
clearing chips by hand or with a rag. Use a brush
or vacuum to clear metal chips.
STOPPING SPINDLE BY HAND. Stopping the
spindle by putting your hand on the workpiece
or chuck creates an extreme risk of entangle-
ment, impact, crushing, friction, or cutting hazards.
Never attempt to slow or stop the lathe spindle with
your hand. Allow the spindle to come to a stop on
its own or use the brake.
TOOL SELECTION. Cutting with an incorrect or
dull tool increases the risk of accidental injury due
to the extra force required for the operation, which
increases the risk of breaking or dislodging com-
ponents that can cause small shards of metal to
become dangerous projectiles. Always select the
right cutter for the job and make sure it is sharp. A
correct, sharp tool decreases strain and provides
a better finish.

SECTION 2: POWER SUPPLY
Availability
Before installing the machine, consider the avail-
ability 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 electrican 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.
G0602 Full-Load Rating...........................13.6A
G0752 Full-Load Rating ..............................12A
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 over-
loading the machine during operation and make
sure it is connected to a power supply circuit that
meets the requirements in the following section.
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: The circuit requirements listed in this man-
ual 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 mul-
tiple machines will be running at the same time,
consult a qualified electrician to ensure that the
circuit is properly sized for safe operation.
A power supply circuit includes all electrical
equipment between the main breaker box or fuse
panel in your building and the incoming power
connections inside the machine. This circuit must
be safely sized to handle the full-load current that
may be drawn from the machine for an extended
period of time.
Circuit Requirements
This machine is prewired to operate on a 110V
power supply circuit that has a verified ground and
meets the following requirements:
Nominal Voltage ............................... 110V/120V
Cycle ..........................................................60 Hz
Phase ........................................... Single-Phase
Minimum Circuit Size (G0602) .......... 20 Amps
Minimum Circuit Size (G0752) .......... 15 Amps

Model G0602/G0752 (Mfg. Since 11/12) -15-
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 nec-
essary, do not connect the equipment-grounding
wire to a live (current carrying) terminal.
Check with a qualified electrician or service per-
sonnel 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, discon-
nect 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 may
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
contain a ground wire, match the required plug
and receptacle, and meet the following require-
ments:
Minimum Gauge Size ...........................14 AWG
Maximum Length (Shorter is Better).......50 ft.
Figure 9. Included 5-15 plug and receptacle.

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.
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.
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 ground-
ing plug (similar to the figure below). The plug
must only be inserted into a matching receptacle
(outlet) that is properly installed and grounded in
accordance with all local codes and ordinances.

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.
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 preven
-
tative, but the following steps work well in a wide
variety of situations. Always follow the manufac
-
turer’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)
Basic steps for removing rust preventative:
1.
Put on safety glasses.
2.
Coat the rust preventative with a liberal
amount of cleaner/degreaser, then let it soak
for 5–10 minutes.
3.
Wipe off the surfaces. If your cleaner/degreas-
er 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.
4.
Repeat Steps 2–3 as necessary until clean,
then coat all unpainted surfaces with a quality
metal protectant to prevent rust.
Gasoline or products
with low flash points can
explode or cause fire if
used to clean machin-
ery. Avoid cleaning with
these products.
Many cleaning solvents
are toxic if concentrat-
ed amounts are inhaled.
Only work in a well-venti-
lated 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.
