ELECTRICAL EQUIPMENT INJURY RISKS. You
can be shocked, burned, or killed by touching live
electrical components or improperly grounded
machinery. To reduce this risk, only allow qualified
service personnel to do electrical installation or
repair work, and always disconnect power before
accessing or exposing electrical equipment.
DISCONNECT POWER FIRST.
Always disconnect machine from power supply BEFORE making
adjustments, changing tooling, or servicing machine.
This prevents an injury risk from unintended startup
or contact with live electrical components.
EYE PROTECTION. Always wear ANSI-approved
safety glasses or a face shield when operating or
observing machinery to reduce the risk of eye
injury or blindness from flying particles. Everyday
eyeglasses are NOT approved safety glasses.
OWNER’S MANUAL. Read and understand this
owner’s manual BEFORE using machine.
TRAINED OPERATORS ONLY. Untrained operators have a higher risk of being hurt or killed.
Only allow trained/supervised people to use this
machine. When machine is not being used, disconnect power, remove switch keys, or lock-out
machine to prevent unauthorized use—especially
around children. Make workshop kid proof!
DANGEROUS ENVIRONMENTS. Do not use
machinery in areas that are wet, cluttered, or have
poor lighting. Operating machinery in these areas
greatly increases the risk of accidents and injury.
MENTAL ALERTNESS REQUIRED. Full mental
alertness is required for safe operation of machinery. Never operate under the influence of drugs or
alcohol, when tired, or when distracted.
For Your Own Safety, Read Instruction
Manual Before Operating This Machine
The purpose of safety symbols is to attract your attention to possible hazardous conditions.
This manual uses a series of symbols and signal words intended to convey the level of importance of the safety messages. The progression of symbols is described below. Remember that
safety messages by themselves do not eliminate danger and are not a substitute for proper
accident prevention measures. Always use common sense and good judgment.
Indicates a potentially hazardous situation which, if not avoided,
MAY result in minor or moderate injury. It may also be used to alert
against unsafe practices.
Indicates a potentially hazardous situation which, if not avoided,
COULD result in death or serious injury.
Indicates an imminently hazardous situation which, if not avoided,
WILL result in death or serious injury.
This symbol is used to alert the user to useful information about
proper operation of the machine.
NOTICE
SECTION 1: SAFETY
-10 -
G0509 & G0509G 16" x 40" Lathe
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.
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

Additional Safety Instructions for Lathes
1. UNDERSTANDING THE MACHINE: Read
and understand this manual before operating machine.
2. CLEANING MACHINE: To avoid entanglement and lacerations, do not clear chips by
hand. Use a brush, and never clear chips
while the lathe is operating.
3. USING CORRECT TOOLING: Always select
the right cutter for the job, and make sure
cutters are sharp. The right tool decreases
strain on the lathe components and reduces
the risk of unsafe cutting.
4. ELIMINATING PROJECTILE HAZARDS:
Always remove the chuck key, and never
walk away from the lathe with the chuck key
installed. Always make sure workpiece is
securely held in chuck before starting lathe.
A workpiece thrown from the chuck could
cause severe injury.
5. AVOIDING OVERLOADS: Always use the
appropriate feed and speed rates.
6. PREVENTING A CUTTING TOOL/CHUCK
CRASH: Always release automatic feeds
after completing a job, and never leave lathe
unattended while it is running.
7. AVOIDING STARTUP INJURIES: Make
sure workpiece, cutting tool, and tool post
have adequate clearance before starting
lathe. Check chuck clearance and saddle
clearance before starting the lathe. Make
sure spindle RPM is set correctly for part
diameter before starting the lathe. Large
parts can be ejected from the chuck if the
chuck speed is set too high.
8. CHUCK SAFETY: Chucks are surprisingly
heavy and awkward to hold, so protect your
hands and the lathe ways. Always use a
chuck cradle or piece of plywood over the
lathe ways.
9. WORKPIECE SUPPORT: Support a long
workpiece if it extends from the headstock
so it will not wobble violently when the lathe
is turned ON. If workpiece extends more
than 2.5 times its diameter from the chuck,
support it by a center or steady rest, or it
may deflect and fall out of the chuck while
cutting.
10. AVOIDING ENTANGLEMENT INJURIES:
Never attempt to slow or stop the lathe
chuck or mill spindle by hand; and tie back
long hair, ponytails, loose clothing, and
sleeves so they do not dangle.
Like all machinery there is potential danger
when operating this machine. Accidents are
frequently caused by lack of familiarity or
failure to pay attention. Use this machine
with respect and caution to lessen the possibility of operator injury. If normal safety
precautions are overlooked or ignored, serious personal injury may occur.

Lifting & Moving
the Lathe
This lathe is an extremely
heavy machine. Serious
personal injury or death
may occur if safe lifting
and moving methods are
not followed. Seek assistance from a professional
rigger if you are unsure
about your abilities or
maximum load ratings of
your lifting equipment.
This lathe can be placed on the included leveling
studs and cast-iron feet. If the lathe must be secured to the floor, refer to a professional machine
installer for options. In either case, the lathe must
be sitting flat at each mounting point, and the ways
must be perfectly level. The bed cannot be twisted
or bent. If a misalignment condition arises, shim
the lathe where it mounts to the floor, or adjust the
feet studs until the bed and ways are in alignment
as shown by precision machinist's levels.
Double check weight ratings and connections of
the lifting system, cables, chains pins, and clevis
links before lifting and moving the lathe to your
prepared location. Do not attempt to lift or move
this lathe if you are unsure about any aspect. Seek
assistance from a professional rigger if required.
When lifting, you must move the carriage and
tailstock to the right and lock into place as shown
in Figure 6 to provide counter-balance.

Mounting to Shop
Floor
We recommend that the lathe is bolted to the floor.
Because floor materials may vary, floor mounting
hardware is not included. Since this is a precision
machine, it is important to level the machine with
a precision level when mounting.
Bolting to Concrete Floors
Lag shield anchors with lag bolts (Figure 7) and
anchor studs (Figure 8) are two popular methods for anchoring an object to a concrete floor.
We suggest you research the many options and
methods for mounting your machine and choose
the best that fits your specific application.
NOTICE
Anchor studs are stronger and more permanent alternatives to lag shield anchors;
however, they will stick out of the floor,
which may cause a tripping hazard if you
decide to move your machine.

Tailstock Setup
The tailstock alignment was set at the factory with
the headstock. However, we recommend that you
take the time to ensure that the tailstock is aligned
to your own desired tolerances.
To align the tailstock:
1. Center drill a 6'' long piece of bar stock on
both ends. Set it aside for use in Step 4.
2. Make a dead center by turning a shoulder
to make a shank. Flip the piece over in the
chuck and turn a 60° point (Figure 13). As
long as it remains in the chuck, the point of
your center will be accurate to the spindle
axis.
Note: Keep in mind that the point will have
to be refinished whenever it is removed and
returned to the chuck.
4. Attach a lathe dog to the bar stock from
Step 1 and mount it between the centers (as
shown in Figure 14).
Figure 14. Bar stock mounted on centers.
5. Turn approximately 0.010" off the diameter.
6. Mount a dial indicator so that the plunger is
on the tailstock barrel (Figure 15).
Figure 13. Finished dead center.
3. Place the dead center in your tailstock.

Looking down from above.
Figure 15. Adjusting for headstock end taper.
7. Measure the stock with a micrometer. If
the stock is wider at the tailstock end, the
tailstock needs to be moved toward the cutter
the amount of the taper (Figure 15).
-23-
— If the stock is thinner at the tailstock end,
the tailstock needs to be moved away from
the operator by at least the amount of the
taper (Figure 16).
Gap Removal
Your lathe has a gap section below the spindle
that can be removed for turning large diameter
parts. This gap was installed, then ground at the
factory during lathe assembly for precise fit and
alignment. Factors during original lathe assembly apply additional forces to the gap; therefore,
replacing the gap to the original position will be
very difficult. We don't recommend removing
the gap. If removed for turning large diameter
parts, reinstallation to exact factory alignment
is nearly impossible. The only option is to
then leave the gap out and lose carriage travel
near the chuck.
Looking down from above.
Figure 16. Adjusting for tailstock end taper.
NOTICE
DO NOT forget to lock the tailstock to the
ways after each adjustment.
8. Loosen the tailstock lock lever and adjust the
tailstock offset by the amount of the taper
by turning the adjustment set screw (Figure
17). Turn another 0.010'' off of the stock and
check for taper. Repeat as necessary until
the desired amount of accuracy is achieved.
Adjustment Screw
To remove the gap:
1. Remove the four cap screws from the bottom
of the gap and two from the ends of the ways
(see Figure 18).

Spindle Speeds
Spindle Speed Lever
The spindle speed or RPM is controlled by two
speed control levers at the top of the headstock
and the 2-speed motor switch located on the lathe
base (Figure 19). The 2-speed motor allows for
the low and high range speed options presented
in columns 1 and 2 shown in Figure 19. Below is
an example how to set the spindle to 1800 RPM.
See Figure 19 for the following example:
1. Move the 2-speed motor switch so it points to
position 1.
Note: Position "1" on the switch activates
both #1 columns on the speed chart.
Position "2" activates both #2 columns on the
speed chart.
Position "I", the central position on the
switch, cuts power to the motor.
2. Move the spindle orange/blue range lever so
it points to the right-hand orange-low range
column number 1.
Note: The spindle orange/blue range lever
must point to which ever range column your
RPM is listed in.
