Trigger
Depress the trigger to rotate the chuck. The lever must be
in a forward or reverse position to operate. The trigger
can be locked in the OFF position. Locking the trigger in
the OFF position helps to reduce the possibility of
accidental starting the drill when not in use. Place the
lever in the center position to lock the trigger. Lock the
trigger when not in use.
Torque Control
Adjust the amount of torque by turning the torque
adjusting ring. The torque control prevents the heads of
smaller diameter screws from twisting off when correctly
set. Fastening torque is greater as the numerals are
larger.
To select any of the numbers, rotate torque adjusting ring
until desired number aligns with the arrow at the top of
the housing.

The drill has full torque when set in a drill position.
Overloading and stalling the drill while in the drill position
can cause motor burnout and can dramatically reduce
battery life.
Selecting Speed
IMPORTANT
Make sure the drill comes to complete stop
before changing speeds. Otherwise, damage to
gearing may result.
To select the high speed (low torque) setting, turn the
tool off and permit to stop. Slide the Hi-Lo switch to the
right, position 2.
To select the low speed (high torque) setting, turn the
tool off and permit to stop. Slide the Hi-Lo switch to the
left, position 1, as shown.

Removing and
Installing Drill Bits
This drill is fitted with a single sleeve keyless chuck for
one-handed operation of chuck. To insert a drill bit or
other accessory, follow the steps listed below:
1. Lock the trigger switch in OFF position.
2. Grasp the black sleeve of the chuck with one hand and
use the other hand to secure the tool. Rotate the
sleeve counterclockwise far enough so that chuck
opens sufficiently to accept the desired accessory.
3. Insert the accessory about 3/4" into the chuck and
tighten securely by rotating the chuck sleeve
clockwise with one hand while holding the tool with
the other. To remove the accessory, repeat step 2
listed above.
WARNING
Do not attempt to tighten the drill bit (or other
accessory) by gripping the front part of the chuck
and turning the tool on. Personal injury may
result. Always lock trigger switch in OFF position
when changing accessories.
