WARNING: Never hold the
chuck body with one hand and
use the drill power to rotate the
drill body to loosen or tighten
bits. Serious injury may result.
1. Remove drill plug from the
power source.
2. Rotate chuck collar (1) in a
counter clockwise direction until the
chuck jaws (2) open wide enough to
accept the bit (3) (Fig. 3).
3. Insert the bit into the chuck
the full length of the jaws or until the
spiral portion of the bit is near the
chuck jaws. Raise the front of your
drill slightly to prevent the bit from
falling out of the chuck jaws.
4. Tighten the chuck jaws onto
the bit by turning the chuck body in
a clockwise direction.
NOTE: Make sure the bit is properly
aligned in the jaws and NOT at an
angle. An improperly aligned bit
could be thrown from the chuck
when the drill is started.
5. Finish tightening the chuck
jaws by inserting the chuck key
(4) into one of three holes (5) in
the chuck body. Rotate chuck key
clockwise until drill bit is held firmly
in place by the chuck jaws.
NOTE: Do NOT use a wrench or
pliers on the chuck key. You may
damage the key or the chuck.
WARNING: Do not insert the
drill bit into the chuck and tighten
as shown in Fig. 4. The drill bit
MUST be properly inserted with
all three of the chuck jaws holding
the bit centered in the chuck.
Failure to properly insert the drill
bit could cause the drill bit to be
thrown from the chuck, resulting
in possible serious injury or
damage to the chuck.
