Mill Operations

The powered operations of the MI mill are done at the control panel, which is
located on the movable arm to the left of the mill.

The only electrical control not located on this main panel is the master power
switch. It is located on the left side of the large electrical box that is attached
to the rear of the mill column.  As a safety feature, the master power switch
also has the ability to accept a padlock to prevent unauthorized use of the
machine.

Simple instruction for Operating Machine

1.

Raise and lower the headstock on its rack and pinion mechanism by
using   the   crank.     When   the   desired   height   is   reached,   tighten   the
locking bolts to avoid vibration.

2.

Head  may  be  rotated  45°  in  either  direction.  Loosen  the  three   lock
nuts. Adjust the head to the desired angle, and then tighten the heavy
duty head lock nuts.

3.

Move the table from side to side by using the longitudinal handwheel,
and from front to back by using the cross handwheel .

4.

Adjust   the   positive   depth   stop   gauge   according   to   desired   working
depth. 

Turning Machine On

1.

Rotate the "E-STOP" button clockwise to assure it is not pushed in. This
button is an emergency stop and it will stay in the power off position
when pushed in. It must be rotated clockwise to allow it to go into the
power on mode and operate the machine.

2.

When the E-Stop is out turns on the power and will illuminate the green
"POWER" light.

The machine is now powered on!
