Machine Description
The metal lathe is used to remove material from
a workpiece that is mounted to the spindle and
rotated over the bed. The cutting tool is mounted
alongside the bed and moved against the spinning workpiece to cut it.
Typical metal lathe cutting operations include facing, 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.
The G0765 features an electronic variable-speed
control and digital RPM display that make it possible to select speeds within the selected range
while the machine is running.

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 hearing 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 modifications—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.
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 during 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 recommended accessories. Using improper accessories 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 disconnecting 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.
GUARDS & COVERS. Guards and covers reduce
accidental contact with moving parts or flying
debris. Make sure they are properly installed,
undamaged, and working correctly.

Additional Safety for Metal Lathes
Serious injury or death can occur from getting entangled in, crushed between, or struck by
rotating parts on a lathe! Unsecured tools or workpieces attached to rotating objects can also
strike nearby operators with deadly force. To minimize the risk of getting hurt or killed, anyone
operating this machine MUST completely heed the hazards and warnings below.
CLOTHING, JEWELRY & LONG HAIR. Tie back
long hair, remove jewelry, and do not wear loose
clothing or gloves. These can easily get caught on
rotating parts and pull you into lathe.
ROTAT ING PARTS. Always keep hands and body
at a safe distance from rotating parts—especially
those with projecting surfaces. Never hold anything against rotating workpiece, such as emery
cloth, that can pull you into lathe.
GUARDING. Guards and covers protect against
entanglement or flying objects. Always ensure they
are properly installed while machine is running.
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.
SAFE CLEARANCES. Before starting spindle,
verify workpiece has adequate clearance by handrotating it through its entire range of motion.
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.
SPINDLE SPEEDS. Using spindle speeds that are
too fast for the workpiece or clamping equipment
can cause rotating parts to come loose and strike
nearby people with deadly force. Always use slow
spindle speeds with large or non-concentric workpieces. Never exceed rated RPM of the chuck.
CHUCKS. Chucks can be heavy and difficult to
hold. During installation and removal, protect your
hands and precision bed ways by using a chuck
cradle or piece of plywood over the bed ways. Use
lifting equipment, as necessary, for large chucks.
LONG STOCK SAFETY. Long stock can whip
violently if not properly supported. Always support
any stock that extends from the chuck/headstock
more than three times its own diameter.
CLEARING CHIPS. Metal chips can be razor
sharp. Avoid clearing them by hand or with a rag.
Use a brush or vacuum instead.
SECURE WORKPIECE. An improperly secured
workpiece can fly off spindle with deadly force.
Make sure workpiece is properly secured before
starting the lathe.
STOPPING SPINDLE. Always allow spindle to
completely stop on its own, or use a brake, if
provided. Never put hands or another object on a
spinning workpiece to make it stop faster.
CRASHING. A serious explosion of metal parts
can occur if cutting tool or other lathe component
hits rotating chuck or a projecting part of workpiece. Resulting metal fragments can strike nearby
people and lathe will be seriously damaged. To
reduce risk of crashing, ALWAYS release automatic feeds after use, NEVER leave lathe unattended,
and CHECK all clearances before starting lathe.
TOOL SELECTION. Cutting with incorrect or dull
tooling increases risk of injury from broken or dislodged components, or as a result of extra force
required for operation. Always use sharp tooling
that is right for the job.
SANDING/POLISHING. To reduce risk of entanglement, never wrap emery cloth around rotating
workpiece. Instead, use emery cloth with the aid
of a tool or backing board.
MEASURING WORKPIECE. To reduce risk of
entanglement, never measure rotating workpieces.
-12-
Model G0765 (Mfd. Since 12/13)
Additional Chuck Safety
ENTANGLEMENT. Entanglement with a rotat-
ing chuck can lead to death, amputation, broken
bones, or other serious injury. Never attempt to
slow or stop the lathe chuck by hand, and always
roll up long sleeves, tie back long hair, and remove
any jewelry or loose apparel BEFORE operating.
CHUCK SPEED RATING. Excessive spindle
speeds greatly increase the risk of the workpiece
or chuck being thrown from the machine with
deadly force. Never use spindle speeds faster than
the chuck RPM rating or the safe limits of your
workpiece.
USING CORRECT EQUIPMENT. Many workpieces can only be safely turned in a lathe if additional
support equipment, such as a tailstock or steady/
follow rest, is used. If the operation is too hazardous to be completed with the lathe or existing
equipment, the operator must have enough experience to know when to use a different machine or
find a safer way.
TRAINED OPERATORS ONLY. Using a chuck
incorrectly can result in workpieces coming loose
at high speeds and striking the operator or bystanders with deadly force. To reduce the risk of this hazard, read and understand this document and seek
additional training from an experienced chuck user
before using a chuck.
CHUCK CAPACITY. Avoid exceeding the capacity
of the chuck by clamping an oversized workpiece.
If the workpiece is too large to safely clamp with
the chuck, use a faceplate or a larger chuck if possible. Otherwise, the workpiece could be thrown
from the lathe during operation, resulting in serious
impact injury or death.
CLAMPING FORCE. Inadequate clamping force
can lead to the workpiece being thrown from the
chuck and striking the operator or bystanders.
Maximum clamping force is achieved when the
chuck is properly maintained and lubricated, all
jaws are fully engaged with the workpiece, and
the maximum chuck clamping diameter is not
exceeded.
PROPER MAINTENANCE. All chucks must be
properly maintained and lubricated to achieve
maximum clamping force and withstand the rigors
of centrifugal force. To reduce the risk of a thrown
workpiece, follow all maintenance intervals and
instructions in this document.
DISCONNECT POWER. Serious entanglement or
impact injuries could occur if the lathe is started
while you are adjusting, servicing, or installing the
chuck. Always disconnect the lathe from power
before performing these procedures.

SECTION 2: POWER SUPPLY
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 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
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.
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 requirements in the following section.
For your own safety and protection of
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 multiple 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 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.)
This machine is prewired to operate on a power
supply circuit that has a verified ground and meets
the following requirements:

codes in your area.
Model G0765 (Mfd. Since 12/13)
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.
We do not recommend using an extension cord
with this machine.
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 requirements:
Grounding & Plug Requirements

electrician install the proper outlet with a
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 (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.
