INSTALLING DRILL BITS
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.
This drill is equipped with a single sleeve
keyless chuck. This chuck is designed to
provide easy one handed tightening and
loosening of the chuck jaws.
1.
To open the keyless drill chuck, grasp and
hold the chuck body (1) and rotate it in a
counter-clockwise direction until the chuck
jaws (2) open wide enough to accept the
bit (3) (Fig. 14).
NOTE:
The drill spindle will automatically
lock when the drill is stopped.
2.
Insert the bit into the chuck the full length
of the jaws. Raise the front of your drill
slightly to prevent the bit from falling out of
the chuck jaws.
3.
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.
Make sure the chuck jaws grasp the flat
sides of a screwdriver bit.
4.
Finish tightening the chuck jaws. Firmly
grasp the chuck body with your hand and
rotate it in a clockwise direction.
NOTES:
a) The automatic spindle lock will prevent the
spindle from rotating while the chuck body is
being tightened.
b) As the chuck jaws begin to tighten on the bit,
you will hear a clicking sound. Continue to rotate
the chuck body until the clicking stops and you
can no longer turn it any further BY HAND.
c) Hand-tighten chuck body. Do NOT use pliers.
You will damage the chuck.
WARNING:
Do not insert the drill bit into
the chuck and tighten as shown in Fig. 15 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.
