Headstock Controls
A. Cutting Chart: Used for shifting the lathe
headstock and gearbox into the proper gear
combinations for threading and feeding oper-
ations.
B. Range Splitting Lever: Used to select the
final spindle speed from the set of high or low
range speeds selected by the range lever.
C. Spindle Speed Dial: Positions the head-
stock gears in one of three speed modes. In
each mode, there are four spindle speeds.
The four speed choices are two speeds in
low range, and two speeds in high range. The
range lever selects high or low range, and the
range splitting lever selects one of the two
remaining speeds within that range.
D. Range Lever: Used to select a set of high
or low range spindle speeds from one of the
three spindle speed modes shown on the
spindle speed dial.
E. Gearbox Hi/Lo Lever: This lever puts the
gearbox in high or low range and has no
effect on spindle RPM. I is Hi range, II is low
range.
F. Jog Button: Turns the spindle motor ON
while being pressed and held.
G. Feed/Lead Dial: Used for setting up feed or
threading gearing ratios in conjunction with
quick change gearbox levers.
H. Emergency Stop Button: Stops all machine
functions. Twist clockwise to reset.
I. Lathe Power Switch: Turns power ON/OFF
to the lathe so lathe operations can begin.
J. Power Light: Indicates the lathe is ener-
gized when illuminated.
K. Coolant Pump Switch: Turns coolant pump
ON/OFF.
L. Quick Change Gearbox Levers: Moves the
gearbox gears into particular ratios, which
then turn the leadscrew and feedrod for
threading and power feed operations.
M. Leadscrew/Feedrod Direction Lever:
Changes the rotation direction of the
leadscrew or feedrod so apron or cross feed
will move the opposite direction.

Additional Safety for Metal Lathes
1. READ AND UNDERSTAND THIS
MANUAL BEFORE OPERATING THIS
MACHINE. YOUR SAFETY AND THE
PROPER USE OF THIS MACHINE IS
YOUR RESPONSIBILITY.
2. CLEARING CHIPS. Do not clear chips by
hand or while the lathe is turning.
3. CHUCK KEY SAFETY. Always remove
chuck key. Never walk away from the lathe
with the key in the chuck.
4. TOOL SELECTION. Always select the right
cutter for the job, and make sure they are
sharp. The right tool decreases strain on
the lathe components and provides a better
finish.
5. SECURING THE WORKPIECE. Make sure
workpiece is properly held in chuck before
starting lathe. A workpiece thrown from the
chuck may cause severe injury to yourself
or others.
6. CHANGING GEARS. Turn lathe OFF before
changing speeds. The spindle must be
brought to a complete stop before changing
gears.
7. SUPPORT LONG STOCK. Stock extending
beyond the headstock MUST be supported.
Unsupported stock will begin to whip and
cause serious injury to operator/ bystanders
and cause damage to the lathe. Always turn
supported long stock at slow RPM's.
8. PINCH HAZARDS. Protect your hands and
the precision ground ways. Always use a
chuck cradle or piece of plywood over the
ways of the lathe when servicing chucks.
9. LATHE MAINTENANCE. Never operate
the lathe with damaged or worn parts.
Maintain your lathe in proper working condi-
tion. Perform routine inspections and main-
tenance promptly when needed. Put away
adjustment tools after use.
10. SAFETY CLEARANCES. Make sure
workpiece has adequate clearance before
starting machine. Check tool and tool post
clearance, chuck clearance, and saddle
clearance before starting the lathe.
11. RATES. Always use the appropriate feed
and speed rates.
12. STOPPING LATHE. Never attempt to slow
or stop the lathe chuck by using your
hand.
13. ATTENDANCE. Never walk away from the
lathe while it is running. An unsupervised
lathe that is running invites accidents.
14. LONG HAIR. Tie up long hair. Long hair
poses a risk of entanglement with moving
parts.
15. AUTOMATIC FEEDS. Release any auto-
matic feeds after completing a job.
16. TURNING SPEEDS. Select the turning
speed appropriate for the type of work,
material, and tool bit. Allow the lathe to gain
full speed before beginning a cut.
17. MOTOR DIRECTION. Never reverse motor
direction while the lathe is in motion.
18. GUARDS. Make sure all guards are in
place and working properly.
19. TOOL POST CLEARANCE. Adjust tool
post to provide proper support for the turn-
ing tool you will be using. Test tool post
clearance by rotating workpiece by hand
before turning lathe ON.
20. CRASHES. Make sure no part of the tool,
tool holder, compound slide, cross slide,
or carriage will contact the chuck during
operation.

Glossary of Terms
G0600 20" x 60" Big Bore Lathe -13-
SECTION 2: CIRCUIT REQUIREMENTS
Serious personal injury could occur if you
connect the machine to the power source
before you have completed the set up pro-
cess. DO NOT connect the machine to the
power source until instructed to do so.
Full Load Amperage Draw
G0600 10 HP 220V 3-Phase .................28 Amps
Circuit Requirements
We recommend connecting your machine to a
dedicated and grounded circuit that is rated for
the amperage given below. Never replace a circuit
breaker on an existing circuit with one of higher
amperage without consulting a qualified electri-
cian to ensure compliance with wiring codes. If
you are unsure about the wiring codes in your
area or you plan to connect your machine to a
shared circuit, consult a qualified electrician.
Minimum Circuit .......................................40 Amp
220V Connection Type
For 220V 3-phase connection of this lathe, we
recommend hardwiring your machine to a power
supply box with a safety shutoff. A qualified elec-
trician should determine the best cord to use in
your environment.
G0600 220V 3-Phase ............................Hardwire
Grounding
In the event of an electrical short, grounding
reduces the risk of electric shock. The grounding
wire in the power cord must be properly connected
to the grounding prong on the plug; likewise, the
outlet must be properly installed and grounded.
All electrical connections must be made in accor-
dance with local codes and ordinances.
Electrocution or fire could
result if this machine is
not grounded correctly
or if your electrical con-
figuration does not com-
ply with local and state
codes. Ensure compliance
by checking with a quali-
fied electrician!
If your lathe is connected to a phase converter
for 3-phase power, the power from the manufac-
tured power leg (sometimes called the wild wire or
manufactured leg) can fluctuate.
Make sure that when you connect the lathe to the
phase converter that you connect the "Wild Wire"
or the "Manufactured Leg" from the phase con-
verter to the lathe input lead L3. Otherwise, your
lathe may not start properly, and magnetic switch
chatter and transformer damage will occur.
Phase Converter
220V 3-Phase
Operation
Extension Cords
We do not recommend the use of extension cords.
Instead, arrange the placement of your equipment
and the installed wiring to eliminate the need for
extension cords.
