—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.

10.With the spindle lever in the down position, the spindle should be rotating counterclockwise— down and toward you as you face the lathe.

—if the spindle and chuck are not rotating counterclockwise, the power supply is connected out-of-phase. Stop the machine, disconnect it from power, then follow the instructions in the Correcting Phase Polarity section on Page 17. After correcting the wiring, repeat Steps 7–10.

11.press the STOP button to turn the lathe OFF, then, without resetting the STOP button, try to restart spindle rotation. The spindle should not start.

—if spindle rotation does start with the STOP button pressed in, the STOP button safety is not operating correctly. This safety feature must operate properly before continuing operation. Use the spindle lever to stop the lathe, disconnect it from power, and call Tech Support for help.

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

13.push the foot brake. The spindle should come to a quick stop.

—if the brake pedal has no effect on the lathe, push the STOP button, and refer to Brake & Switch on Page 80 to make any required adjustments.

14.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.
