Move the spindle ON/OFF 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.
Push the STOP button. The spindle should
come to a slow stop.
16.
Move the spindle ON/OFF 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.
17.
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

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.
20.
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.

Push the STOP button in, move the spindle
ON/OFF lever to the OFF position, then
replace the end gear cover.
22.
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.
23.
Move the chuck guard back down into
operating position.
24.
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).
25.
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
.
