OPERATION MANUAL
SETTING VARIABLE HEAD SPEEDS
With the variable speed head change the speed only when
the spindle is turning.
The variable speed handwheel is used to control the spindle
speed. The handwheel is located on the right side of the mill
head. The speeds for high and low speed ranges are dis-
played on the panel on the front of the mill head (B, Fig. 6).
All speed changes must be made while the motor is running.
Attempting speed changes with the motor not running can
result in damage to the drive mechanism.
