VARIABLE SPEED CONTROLLED
TRIGGER SWITCH
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
to maximum nameplate RPM by the pressure
you apply to the trigger. Apply more pressure
to increase the speed and release pressure to
decrease speed (Fig. 1).

"OFF" position to help prevent

RAPID SHUT-OFF
Rapid Shut-Off 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

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
