17. Move the spindle ON/OFF lever to the OFF
(middle) position, reset the STOP button by
twisting it clockwise until it pops out, then
restart spindle rotation.

to a quick stop.
— If the brake pedal has no effect on the
lathe, push the STOP button, and refer to
the Brake & Switch subsection on Page
80 to make any required adjustments.
After verifying the brake works correctly,
continue with the next step.

cover. This trips a safety switch that should
prevent the lathe from starting while the
cover is removed.
20. Stand away from all the exposed gears on
the side of the headstock, and attempt to
start the lathe.
— If the lathe starts with the end gear
cover removed, the safety switch is not
operating correctly. This safety feature
must operate properly before continuing.
Press the STOP button to turn the lathe
OFF, disconnect the lathe from power,
and call Tech Support for help.
21. Push the STOP button in, move the spindle
ON/OFF lever to the OFF position, then
replace the end gear cover.
22. Lift the chuck guard up—this will activate
the chuck guard safety switch. Reset the
STOP button and attempt to start the lathe.
— If the lathe starts with the chuck guard
in the up position, the safety switch is not
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. 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 72 for detailed instructions).
24. Re-start the lathe, use the coolant pump
switch on the control panel to start the
pump, then open the valve. Verify that the
coolant flows from the nozzle, then close the
valve and turn the pump OFF.
Congratulations! The test run is complete. Turn
the lathe OFF and perform the Spindle Break-
In procedure on the next page.
After the first 16 hours of use, the V-belts will
stretch and seat into the pulley grooves. The
V-belts must be properly re-tensioned after
this period to avoid reducing their useful life.
Refer to the V-Belts subsection on Page 80
for detailed instructions.
