Power Shutdown
It is important to shut the power OFF when the
mill/drill is not in use. Leaving the power ON
keeps the circuit board cooling fan running. This
will cause unnecessary wear on the fan and elec-
trical system.
To completely shut the system power OFF:
1. Turn the SPINDLE RPM Control Knob OFF.
2. Turn the MAIN POWER Switch OFF.
3. Press the EMERGENCY STOP Button. At
this point the green power light and the
amber fan power light should not be lit.

Spindle & Headstock

a drill press (see

To use the rapid downfeed:
1. Make sure the quill lock is released and the
headstock is locked in position.
2. Turn the quill feed levers to lower and raise
the spindle.
Note: For maximum rigidity and accuracy
when milling, keep the spindle retracted and
locked inside the head as far as possible.
