5.13 Drill Motor Operation 21.40
The Drill Motor has its own power switch located on the motor body. This switch should always
be in the ON position. Drill motor operation is controlled by the Power Switch on the machine.
Warning: Do not run the motor for more than two hours at a time. The motor requires a ½ hour
cool down period after each two hour period.
The Drill Motor is attached to the Motor Carriage by a bolt that is secured with a black T-Knob.
This bolt may become loose due to vibration causing inconsistent pilot hole boring and/or
frequently broken drill bits.
