PREPARATION
13. Move the spindle lever down to start the
spindle rotating counterclockwise (down
toward the front of the lathe).
— If the spindle rotates in the opposite
direction (clockwise), the power supply
phase polarity may be incorrect. Refer to
Correcting Phase Polarity on Page 92
to resolve this.
14. Observe the lathe and listen for any
abnormal noises or vibration. The lathe
should run smoothly.
15. Move the spindle lever to the OFF (middle)
position, let the spindle come to a complete
stop, then move the lever up to reverse
spindle rotation.
16. Push the STOP button. The spindle should
come to a slow stop.
17. With the STOP button pushed in, attempt
to start spindle rotation—the spindle should
not start.
— If the spindle does start, the STOP button
is not working properly. This safety
feature must operate properly before
continuing. Turn the master power switch
OFF, disconnect the lathe from power,
then call Tech Support for help.
18. Move the spindle lever up to the OFF
(middle) position, reset the STOP button by
twisting it clockwise until it pops out, then
restart spindle rotation by moving it down
again.
19. Press the foot brake. The spindle should
come to a quick stop.
— If the foot brake has no effect on the
stopping speed of the spindle, push the
STOP button and refer to Brake Service
on Page 82 to adjust the brake.
20. Push the STOP button in and move the
spindle lever up to the OFF (middle) position
to prevent accidental start-up.
21. Remove the end gear cover from the left side
of the headstock. There is a safety switch
that prevents the spindle from starting while
this cover is removed.
22. Reset the STOP button, stand away from
all the exposed gears on the side of the
headstock, then attempt to start spindle
rotation—the spindle should not start.
— If the spindle does start with the end gear
cover removed, the safety limit switch is
not adjusted or operating correctly. This
safety feature must operate properly
before continuing. Press the STOP button
to turn the lathe OFF, disconnect it from
power, and call Tech Support for help.
23. Push the STOP button in, move the spindle
lever to the OFF (midddle) position, then
replace the end gear cover.
24. Reset the STOP button, then lift the chuck
guard up—this will activate the chuck guard
safety switch to prevent spindle rotation.
Attempt to start spindle rotation—the
spindle should not start.
— If the spindle starts with the chuck guard
in the up position, the safety switch is
not adjusted or operating correctly. This
safety feature must operate properly
before continuing. Press the STOP button
to turn the lathe OFF, disconnect it from
power, and call Tech Support for help.
25. Move the chuck guard back down into
operating position.
26. Point the coolant nozzle down into the chip
drawer and verify that there is coolant in the
reservoir (refer to Coolant System Service
on Page 75 for detailed instructions).
27. Use the coolant pump switch on the control
panel to start the pump, then open the valve
at the base of the nozzle. Verify that the
coolant flows from the nozzle, then close the
valve and turn the pump OFF.
Congratulations! The test run is complete.

procedure.
