REVERSE
This tool has the feature of being 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.
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.
WARNING:
Your drill should never be connected to power supply
when you are assembling parts, making adjustments,
installing or removing drill bits, cleaning, or when not
in use. Disconnecting your drill will prevent accidental
starting that could cause serious personal injury.
KEYLESS CHUCK
See Figure 4.
A keyless chuck has been provided with your 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. Arrows on the chuck indicate which
direction to rotate the chuck body in order to LOCK
(tighten) or UNLOCK (release) the chuck jaws. Grasp
and hold the collar of the chuck with one hand. Rotate the
chuck body with your other hand. Insert drill bit straight
into the chuck the full length of the jaws, and tighten
securely by rotating the chuck body in a clockwise
direction.
WARNING:
Do not hold chuck body with one hand and use 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.
INSTALLING BITS
See Figure 4.
■ Unplug your drill.
WARNING:
Failure to unplug your drill could result in accidental
starting causing serious injury.
■ Open or close the chuck jaws to a point where the
opening is slightly larger than the bit size you intend
to use. Also, raise the front of your drill slightly to
keep the bit from falling out of the chuck jaws.
■ Insert drill bit straight into chuck the full length of the
jaws as shown in figure 4.
■ Tighten the chuck jaws on drill bit.
■ To tighten the chuck jaws on drill bit; grasp and hold
the collar of the chuck with one hand, while rotating
the chuck body with your other hand.

jaws.
