15. Move the spindle lever to the OFF (middle)
position. Remove the end gear cover from the
left side of the headstock. This activates a
safety switch that should prevent the spindle
from starting while this cover is removed.
16. Stand away from all the exposed gears on
the side of the headstock, and attempt to
start spindle rotation. The spindle should not
start.
— If spindle rotation does start with the end
cover removed, the safety switch is not
operating correctly. This safety feature
must operate properly before continuing
operation. Press the STOP button to turn
the lathe OFF, disconnect it from power,
and call Tech Support for help.
17. Push the STOP button in, move the spindle
lever to the OFF position, then replace the
end gear cover.
18. Lift the chuck guard up—this will activate
the chuck guard safety switch. Reset the
STOP button and attempt to start spindle
rotation. The spindle should not start.
— If spindle rotation does start with the
chuck guard in the up position, the safety
switch is not operating correctly. This
safety feature must operate properly
before continuing operation. Press the
STOP button to turn the lathe OFF,
disconnect it from power, and call Tech
Support for help.
19. Re-start spindle rotation, use the cutting
fluid pump switch on the control panel to
start the pump, then open the valve. Verify
that the cutting fluid flows from the nozzle,
then turn the pump OFF.
Congratulations! The test run is complete.
Turn the lathe OFF and perform the following
Spindle Break-In procedure.
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 ensure proper power
transmission and avoid reducing the life of the
belts. Refer to the V-Belts subsection on Page
77 for detailed instructions.
