13.To reset the STOP button and enable power to the lathe electrical controls, twist the STOP button clockwise until it pops out. The power light on the control panel should illuminate (see Figure 29 on Page 28).

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.
