the tool off, release the trigger switch. Your tool is equipped
with a brake. The chuck will stop as soon as the trigger
switch is fully released.
Variable speed Trigger switch
The variable speed trigger switch enables you to select
the best speed for a particular application. The farther you
squeeze the trigger switch, the faster the tool will operate.
For maximum tool life, use variable speed only for starting
holes or fasteners.

recommended. It may damage the trigger switch and
should be avoided.

CAUTION: Do not stare into worklight. Serious eye
injury could result.
There is a worklight 7 located on the tool. The worklight
is activated when the trigger switch is depressed, and will
automatically turn off 20 seconds after the trigger switch
is released. If the trigger switch remains depressed, the
worklight will remain on.

Forward/Reverse Control Button (Fig. A)
A forward/reverse control button
direction of bit rotation 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.
SHOCKS® Active Vibration Control System
For best vibration control, hold the tool as described in
Proper Hand Position and apply just enough pressure so
the damping device on the main handle is approximately
mid stroke. The hammer only needs enough pressure to
engage the active vibration control. Applying too much
pressure will not make the tool actuate faster and active
vibration control will not engage.
