When illuminated, the power lamp (Figure 6) indicates that power is being supplied to the lathe/ mill. Pressing the red emergency stop button will cut power for machine operations. Twisting the emergency stop button clockwise and letting it pop out will restore power for machine operations and reset the emergency stop button.

Note: The Spindle Rotation ON/OFF Lever (Figure 8) on the apron starts the spindle motor in a particular direction.

TURN OFF and LOCK your master power switch so no power is available to the lathe/ mill, and make sure the spindle is stopped before proceeding with any adjustments or maintenance. Failure to comply may result in serious personal injury or death.
