1. Switch
operation
The rotation speed of the drill bit can be controlled steplessly by varying the amount that
the trigger switch is pulled. Speed is low when the trigger switch is pulled slightly and
increases as the switch is pulled more. Continuous operation may be attained by pulling the
trigger switch and depressing the stopper. To turn the switch OFF, pull the trigger switch
again to disengage the stopper, and release the trigger switch to its original position.
However, the switch trigger can only be pulled in halfway during reverse and rotates at half
the speed of forward operation.
The switch stopper is unusable during reverse.
