DIRECTION OF ROTATION SELECTOR
(FORWARD/REVERSE/CENTER LOCK)
See Figure 2.
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.
Setting the switch trigger in the OFF (center lock) position
helps reduce the possibility of accidental starting when not
in use.
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.
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.

INSTALLING BITS

See Figure 3 - 4.
 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.
WARNING:
Make sure to insert the drill bit straight into the chuck
jaws. Do not insert the drill bit into the chuck jaws at
an angle then tighten, as shown in
cause the drill bit to be thrown from the drill, resulting in
possible serious personal injury or damage to the chuck.
 Rotate the chuck clockwise to tighten the chuck jaws
securely on the bit.
NOTE: Rotate the chuck body in the direction of the ar-
row marked LOCK to tighten the chuck jaws. Do not use
a wrench to tighten or loosen the chuck jaws.
