CHUCK REMOVAL
– cont’d
1. Remove the battery pack from the drill.
2.
Insert a 5/16” or larger hex key (1) into
the chuck (2) and tighten the chuck
jaws securely. Make sure the chuck
jaws (3) are seated on flat surface of
the hex key (Fig. 10).
3. Tap the hex key sharply with a mallet
(4) in a clockwise direction. This action
will loosen the screw in the chuck for
easy removal.
4. Open chuck jaws and remove hex key.
5. Open chuck jaws as far as possible.
6. Remove the chuck screw using a
#2 screwdriver (Fig. 11).
NOTE: Turn screw CLOCKWISE to
remove it. This screw has a left-
handed thread.
7. Insert hex key into chuck and tighten
jaws of chuck securely (Fig. 12). Tap
the hex key sharply with a mallet in a
COUNTER-CLOCKWISE direction.
This will loosen the chuck on the
spindle. The chuck can now be
unscrewed and removed from the
spindle by hand.
RETIGHTENING LOOSE CHUCK
After installing the chuck once it has been
removed, the chuck may become loose on
the spindle and develop a wobble. Also, the
chuck screw may become loose causing
the chuck jaws to bind and prevent them
from closing. To tighten the chuck, follow
these steps:
1. Insert hex key into chuck and tighten
chuck securely.
2. Tap hex key sharply with a mallet in a
CLOCKWISE direction (Fig. 10). This
will tighten the chuck on the spindle.
3. Open chuck jaws and remove the hex
key.
4. Tighten the chuck screw using a #2
screwdriver.
NOTE: Turn screw COUNTER-
CLOCKWISE to tighten it. This screw
has a left-handed thread.
