APPLICATIONS
You may use this product for the purposes listed below:

Drilling in all types of wood products (lumber, plywood,
paneling, composition board, and hardwood)
 Drilling in ceramics, plastics, fiberglass, and laminates
 Drilling in metals
SWITCH TRIGGER
See Figure 2, page 11.
To turn the drill
ON, depress the switch trigger. To turn it
OFF, release the switch trigger.
VARIABLE SPEED
The variable speed switch delivers higher speed and torque
with increased trigger pressure and lower speed with
decreased trigger pressure.
NOTE: You might hear a whistling or ringing noise from the
switch during use. Do not be concerned; this is a normal
part of the switch function.
DIRECTION OF ROTATION SELECTOR
(FORWARD/REVERSE)
See Figure 2, page 11.
The direction of bit rotation is reversible and is controlled
by a selector located above the switch trigger. With the drill
held in normal operating position, the direction of rotation
selector should be positioned to the left of the switch trigger
for drilling. The drilling direction is reversed when the selector
is to the right of the switch trigger.
CAUTION:
To prevent gear damage, always allow the chuck to
come to a complete stop before changing the direction
of rotation.
To stop the drill, release the switch trigger and allow the
chuck to come to a complete stop.
NOTE: The drill will not run unless the direction of rotation
selector is pushed fully to the left or right.
Avoid running the drill at low speeds for extended periods
of time. Running at low speeds under constant usage may
cause the drill to become overheated. If this occurs, cool the
drill by running it without a load and at full speed.
KEYLESS CHUCK
See Figure 3, page 11.
The drill has a keyless chuck that makes it simple to
tighten or release drill bits in the chuck jaws. Grasp and
hold the collar of the chuck with one hand. Rotate the chuck
body with your other hand. The arrows on the chuck indicate
which direction to rotate the chuck body in order to
LOCK
(tighten) or UNLOCK (release) the drill bit.
WARNING:
Do not hold the chuck body with one hand and use the
power of the drill to tighten the chuck jaws on the drill
bit. The chuck body could slip in your hand, or your
hand could slip and come in contact with the rotating
drill bit. This could cause an accident resulting in serious
personal injury.
WARNING:
Always unplug the tool when installing or removing bits,
adjusting settings, or when the tool is not in use. Failure
to unplug the tool may result in accidental starting and
serious personal injury.
BIT STORAGE
See Figure 4, page 11.
When not in use, bits provided with the drill can be placed
in the storage area located on the top of the drill.
INSTALLING BITS
See Figure 5 - 6, page 11.

Unplug the drill.
 Open or close the chuck jaws to a point where the open-
ing is slightly larger than the bit size you intend to use.
Also, raise the front of the drill slightly to keep the bit from
falling out of the chuck jaws.
 Insert the drill bit.
