Variable Speed Trigger Switch (fi g. 1)
To turn the tool on, squeeze the trigger switch (a). To
turn the tool off, release the trigger switch. Your tool
is equipped with a brake. The chuck will stop when
the trigger switch is fully released.
The variable speed switch enables you to start
the application at a slow speed. The further you
squeeze the trigger, the faster the tool will operate.
For maximum tool life, use variable speed only for
starting holes or fasteners.
NOTE: Continuous use in variable speed range is
not recommended. It may damage the switch and
should be avoided.
Forward/Reverse Control Button

direction of the tool and also serves as a lock-off
button.
To select forward rotation, release the trigger switch
and depress the forward/reverse control button on
the right side of the tool.
To select reverse, depress the forward/reverse
control button on the left side of the tool. The center
position of the control button locks the tool in the off
position. When changing the position of the control
button, be sure the trigger is released.
NOTE: The first time the tool is run after changing the
direction of rotation, you may hear a click on start up.
This is normal and does not indicate a problem.

anvil (d, i). The worklights will be activated when the
