Machine Description

The purpose of a metal lathe is to face, turn, knurl,
thread, bore, or cut tapers in a metal workpiece
with perfect accuracy.

During typical operations, the lathe spindle rotates
the workpiece at various speeds against a fixed
cutting tool that is positioned at a particular angle
for the desired type of cut.

The cutting tool is mounted on a tool post, which
is positioned by three different slides that each
move in different directions.

Opposite of the headstock and spindle is a sup­port device called a tailstock. The tailstock can
be slid along the lathe bed and locked in place to
firmly support the end of a workpiece.

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 work­piece 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 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.

Additional Safety for Metal Lathes

Never attempt to slow or stop the lathe spindle with

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 dan­gerous projectiles that could cause severe impact
injuries. Large or non-concentric workpieces must
be turned at slow speeds. Always use the appro­priate 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.

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 entangle­ment, impact, crushing, friction, or cutting hazards.

your hand. Allow the spindle to come to a stop on
its own or use the brake.

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, com­pound rest, cross slide, or carriage will contact the
chuck during operation.

COOLANT SAFETY. Coolant is a very poison­ous biohazard that can cause personal injury from
skin contact alone. Incorrectly positioned coolant
nozzles can splash on the operator or the floor,
resulting in an exposure or slipping hazard. To
decrease your risk, change coolant regularly and
position the nozzle where it will not splash or end
up on the floor.

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 com­ponents 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.

Model G0709 (Mfg. Since 5/11)

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.

This machine is prewired to operate on a 220V
power supply circuit that has a verified ground and
meets the following requirements:

For your own safety and protection of

Note: The circuit requirements listed in this man­ual 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.)

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 Instructions

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.

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.

Serious injury could occur if you connect

The power cord and plug specified under “Circuit
Requirements for 220V”
has an equipment-grounding wire and a ground­ing prong. 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 (see figure below).

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 preven­tative, but the following steps work well in a wide
variety of situations. Always follow the manufac­turer’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)

Site Considerations

Weight Load

Physical Environment

Place this machine near an existing power source.

Shadows, glare, or strobe effects that may distract

Refer to the Machine Data Sheet for the weight
of your machine. Make sure that the surface upon
which the machine is placed will bear the weight
of the machine, additional equipment that may be
installed on the machine, and the heaviest work­piece that will be used. Additionally, consider the
weight of the operator and any dynamic loading
that may occur when operating the machine.

Space Allocation

Consider the largest size of workpiece that will
be processed through this machine and provide
enough space around the machine for adequate
operator material handling or the installation of
auxiliary equipment. With permanent installations,
leave enough space around the machine to open
or remove doors/covers as required by the main­tenance and service described in this manual.

See below for required space allocation.

Children or untrained people
may be seriously injured by
this machine. Only install in an
access restricted location.

The physical environment where the machine is
operated is important for safe operation and lon­gevity of machine components. For best results,
operate this machine in a dry environment that is
free from excessive moisture, hazardous chemi­cals, airborne abrasives, or extreme conditions.
Extreme conditions for this type of machinery are
generally those where the ambient temperature
range exceeds 41°–104°F; the relative humidity
range exceeds 20–95% (non-condensing); or the
environment is subject to vibration, shocks, or
bumps.

Electrical Installation

Make sure all power cords are protected from
traffic, material handling, moisture, chemicals,
or other hazards. Make sure to leave access to
a means of disconnecting the power source or
engaging a lockout/tagout device, if required.

Lighting

Lighting around the machine must be adequate
enough that operations can be performed safely.

Lifting & Moving

Anchoring the machine to the floor prevents it
from tipping or shifting and reduces any vibration
that may occur during operation, resulting in a
machine runs slightly quieter and feels more solid.

If the machine will be installed in a commercial or
workplace setting, or if it is permanently connect­ed (hardwired) to the power supply, local codes
may require that it be anchored to the floor.

If not required by any local codes, fastening the
machine to the floor is an optional step. If you
choose not to do this with your machine, we rec­ommend placing it on machine mounts, as these
provide an easy method for leveling and they have
vibration-absorbing pads.

Lag shield anchors with lag screws (see below)
are a popular way to anchor machinery to a con­crete floor, because the anchors sit flush with the
floor surface, making it easy to unbolt and move
the machine later, if needed. However, anytime
local codes apply, you MUST follow the anchoring
methodology specified by the code.

You must use power lifting equipment and
assistance to lift and move this machine.
Inspect all lifting equipment to make sure
it is in working order and rated for the load
before attempting to lift. Ignoring this warn­ing may lead to serious personal injury or
death.

Anchoring to Floor

Anchoring to Concrete Floors

This lathe has a hole built into each end of the
stand (see Figure 8) that is designed to accept
a sturdy 1" diameter lifting bar. Each bar must
extend far enough from the stand so that chains
or lifting straps can be looped or connected to all
four corners and the lathe can be lifted.

Leveling

For accurate turning results and to prevent
warping the cast iron bed and ways, the
lathe bedways MUST be leveled from side­to-side and from front-to-back on both ends.

Re-check the bedways 24 hours after
installation, two weeks after that, and then
annually to make sure they remain level.

Leveling machinery helps precision components,
such as bedways, remain straight and flat during
the lifespan of the machine. Components on a
machine that is not level may slowly twist due to
the dynamic loads placed on the machine during
operation.

For best results, use a precision level that is at
least 12" long and sensitive enough to show a
distinct movement when a 0.003" shim (approxi­mately the thickness of one sheet of standard
newspaper) is placed under one end of the level.

Lubricating Lathe

It is critical that there is oil in the headstock,
quick change gearbox, and the apron gearbox
before proceeding with the test run. Refer to the
Lubrication instructions on Page 56 for more
details on which type and how much oil to use in
each gearbox.

GEARBOXES MUST

BE FILLED WITH OIL!

NO OIL SHIPPED WITH

MACHINE!

Refer to the Lubrication

Section in this Manual

for Recommended

Oil Type.

See the figure below for an example of a high
precision level.

Adding Cutting Fluid

For detailed instructions on where the cutting
fluid tank is located and how to add fluid, refer to
Cutting fluid System on Page 58.

Model G0709 (Mfg. Since 5/11)

Power Connection

Electrocution or fire
may occur if machine
is ungrounded, incor­rectly connected to
power, or connected to
an undersized circuit.
Use an electrician or
qualified personnel to
ensure a safe power
connection.

Once all preparation steps previously described
in this manual have been completed, the machine
can be connected to the power source. In order to
be connected to the power source, a circuit must
be installed/prepared that meets the requirements
of the lathe, and a power connection method must
be established for that circuit.

Using an incorrectly sized cord causes machine
electrical components and the cord to become
very hot, which can lead to component failure or
result in fire. For best results, use the shortest
length of cord possible, and never use a smaller
cord gauge than the specified minimum.

Test Run

Once assembly is complete, test run the machine
to make sure it runs properly and is ready for reg­ular operation. The test run consists of verifying
the following: 1) The motor powers up and runs
correctly and 2) the stop button safety feature
works correctly.

If, during the test run, you cannot easily locate
the source of an unusual noise or vibration, stop
using the machine immediately, then review
Troubleshooting on Page 59.

If you cannot find a remedy, contact our Tech
Support at [phone] for assistance.

To begin the test run:

1. Make sure you understand the safety instruc-

tions at the beginning of the manual and that
all previous setup sections have been com­pleted.

2. Make sure the lathe is lubricated and the
oil levels are at the full mark. Refer to

Maintenance on Page 53 for details.

3. Make sure the chuck is correctly secured to
the spindle. Refer to Chuck and Faceplate

Spindle Break-In

Before subjecting the spindle to operational loads,
it is essential to complete the break-in process.
This helps ensure maximum life of spindle bear­ings and other precision components by thor­oughly lubricating them before placing them under
load.

After spindle break-in is complete, we recommend
changing headstock and gearbox oil to remove
any metal particles or debris that are present from
the assembly and break-in process.

The break-in must be performed in succession
with the
manual, as the steps in that procedure prepare
the lathe controls for the break-in process.

Test Run procedure described in this

DO NOT perform this procedure indepen­dently of the Test Run section. The lathe
could be seriously damaged if the controls
are set differently than instructed in that
section.

brake has been used, return the spindle ON/OFF
lever to the central position, and all lathe controls
become "LIVE" again.

Chuck & Faceplate

Removal/Installation

This lathe is shipped with a 3-jaw chuck installed,
but also includes a 4-jaw chuck and 12" faceplate.
The chucks and faceplate mount to the spindle
with a D1-5 camlock system, which uses a key to
loosen and tighten camlocks for removal or instal­lation (see Figure 18).

Chuck & Faceplate Removal

1. DISCONNECT LATHE FROM POWER!

2. Lay a chuck cradle (see Figure 20) or a layer

of plywood over the bedways to protect the
precision ground surfaces from damage and
to prevent fingers from being pinched.

Figure 20. Simple chuck cradle made of scrap

lumber.

Figure 18. Chuck key positioned to remove a

typical camlock mounted chuck.

Before the 4-jaw chuck and faceplate can be
installed on the spindle, their respective cam
studs must be installed and adjusted.

To maintain consistent removal and installation
of the chucks and faceplate, each should have a
timing mark that can be lined up with a matching
one on the spindle, so it will be installed in the
same position every time (see Figure 19). Before
removing the 3-jaw chuck, verify that a timing
mark exists. If a mark cannot be found, stamp
your own on both the chuck and spindle.

Marks

PINCH HAZARD! Protect your hands and
the precision ground bedways with plywood
or a chuck cradle when removing the lathe
chuck! The heavy weight of a falling chuck
can cause serious injury.

3. Loosen the cam-locks by turning the key

counterclockwise approximately one-third of
a turn until the mark on the cam-lock aligns
with the single mark on the spindle nose in
Figure 21. If the cam-lock stud does not
freely release from the cam-lock, wiggle the
cam-lock until the cam-lock stud releases.

Note: These cam-locks may be very tight. A

breaker bar may be used to add leverage.

4. Using a dead blow hammer or other soft mal-

let, lightly tap around the outer circumference
of the chuck body to break the chuck free
from the cam-locks and from the spindle nose
taper.

CAUTION: The chuck may come off at this

point, so it is important you are ready to
support its weight.

Large chucks are very heavy. Always get
assistance when removing or installing
large chucks to prevent personal injury or
damage to the chuck or lathe.

2. Place a piece of plywood across the lathe

ways just under the chuck, and use a chuck
cradle if desired.

3. Make sure the chuck taper and spindle taper
mating surfaces are perfectly clean.

4. Inspect and make sure that all camlock studs
are undamaged, are clean and lightly oiled,
and that the camlock stud cap screws are in
place and snug.

—If the camlock studs have not yet been

installed in the chuck or faceplate, com­plete the Camlock Stud Installation on
the next page.

NOTICE

Never install a chuck or faceplate without
having the camlock cap screws in place
or fully tightened. If you ignore this notice,
once installed the chuck may never be able
to be removed since the camlock studs will
turn with the camlocks and never release.

5. Use a rocking motion to carefully remove the

chuck from the spindle (see Figure 22).

—If the chuck does not immediately come off,

rotate the spindle approximately 60˚ and
tap again. Make sure all the marks on the
cams and spindle are in proper alignment.

camlock style chuck.

5. Align the chuck-to-spindle timing marks (see
Figure 24), and slide the chuck onto the

spindle.

6. Turn a camlock with the chuck wrench until
the cam mark falls between the "V" marks as
shown in Figure 23.

— If the cam lock mark stops outside of the

“V” marks, remove the chuck and adjust
the cam stud height of the offending studs
one full turn up or down (see Figure 23).
