When the trigger switch is depressed, the tool
rotates. When the trigger is released, the tool stops.
The rotational speed of the drill can be controlled
by varying the amount that the trigger switch is
pulled. Speed is low when the trigger switch is
pulled slightly and increases as the trigger switch
is pulled more.
When releasing the trigger of the switch, the brake
will be applied for immediate stopping.
6. Change rotation speed.
