INSTALLING DRILL BITS
– cont’d
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. 8).
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) Continue to rotate the chuck body until
the clicking stops and you can no longer
turn it any further BY HAND.
c) Hand-tighten the chuck body. Do NOT
use pliers. You will damage the chuck.
