OFF, release the switch trigger.
The drill has a two-speed feature in the switch. Depress
the switch trigger halfway for driving screws at low speed.
Depress the switch trigger all the way for normal drilling.

SWITCH LOCK

See Figure 7.
The switch trigger can be locked in the

OFF position. This

feature helps reduce the possibility of accidental starting when
not in use. To lock the switch trigger, place the direction of
rotation selector in the center position.

REVERSIBLE

See Figure 8.
This tool is reversible. The direction of rotation 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 for
drilling. The drilling direction is reversed when the selector
is to the right of the switch. When the selector is in center
position, the switch trigger is locked.

CAUTION:

To prevent gear damage, always allow chuck to come
to a complete stop before changing the direction of
rotation.

To stop, release switch trigger and allow the chuck to come
to a complete stop.

KEYLESS CHUCK

See Figure 9.
A keyless chuck has been provided with the drill to allow for
easy installation and removal of bits. As the name implies, you
can hand 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 chuck jaws on drill bit. Chuck
body could slip in your hand or your hand could slip and
come in contact with rotating drill bit. This could cause
an accident resulting in serious personal injury.
