Your tool is equipped with a variable speed
trigger switch. The tool can be turned "ON" or
"OFF" by squeezing or releasing the trigger.
The speed can be adjusted from the minimum

you apply to the trigger. Apply more pressure
to increase the speed and release pressure to
decrease speed (Fig. 1).

ACTIVE RESPONSE TECHNOLOGy™
Active Response Technology™ is a feature
that detects rapid twisting of the drill handle
and quickly cuts power to the motor in order to
limit the movement of the handle. You are
most likely to encounter this condition when
the drilling bit binds in the material or a
fastener binds or bottoms-out to a hard stop in
the material.
In the event a binding condition occurs, an
internal sensor will detect the rapid handle
rotation and quickly cut-off power to the motor,
even while the variable speed trigger switch is
still depressed. The work light on the foot of
the tool will then flash to indicate the system
has been engaged. The light will continue to
flash until the tool's trigger switch is released.
Note that the feature can only function if the
drill handle has freedom to rotate. If you are
working in a confined space, the handle may
not have the ability to rotate such that the
feature can activate.
To free a bound bit, release the trigger and
reposition the handle to a comfortable working
Operating Instructions
Your tool is equipped with a forward/
reversing lever and trigger lock located above
the trigger (Fig. 7). This lever was designed
for changing rotation of the bit, and for locking
the trigger in an "OFF" position.
For forward rotation, (with chuck pointed away
from you) move the lever to the far left (Fig. 7).
For reverse rotation move the lever to the far
right (Fig. 8). To activate trigger lock move
lever to the center off position.
