— When operating correctly, the machine
runs smoothly with little or no vibration
or rubbing noises.
— Investigate and correct strange or
unusual noises or vibrations before
operating the machine further. Always
disconnect the machine from power when
investigating or correcting potential
problems.
15. With the spindle ON/OFF lever in the down
position, verify that the spindle/chuck is
rotating counterclockwise (down and toward
the front of the lathe).
— If the spindle/chuck are not rotating
counterclockwise, the power supply is
likely connected out-of-phase. Stop the
machine, disconnect it from power, then
follow the instructions for Correcting
Phase Polarity Wiring on Page 90.
After correcting the wiring, repeat
Steps 11–15.
16. Press the STOP button to turn the lathe
OFF, then, without resetting the STOP
button, try to restart the lathe with the
spindle ON/OFF lever.
— If the lathe does not start with the STOP
button pressed in, the STOP button safety
feature is working properly.
— If the lathe does start with the STOP
button pressed in, the STOP button safety
is not operating correctly. This safety
feature must operate properly before
continuing. Use the spindle ON/OFF
lever to stop the lathe, disconnect it from
power, and call Tech Support for help.
