REMOVING THE CHUCK
– cont’d
5. Open the chuck jaws as far as
possible.
6. Remove the chuck screw using a
#2 screwdriver (Fig. 12).
NOTE:
Turn the screw CLOCKWISE to
remove it. This screw has a left-handed
thread.
7. Insert the hex key into the chuck and
tighten jaws of chuck securely
(Fig. 13). 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 A LOOSE CHUCK
After installing a chuck that has previously
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 the hex key into the chuck and
tighten the chuck securely.
2. Tap the hex key sharply with a mallet
in a CLOCKWISE direction (Fig. 14).
This will tighten the chuck on the
spindle.
3. Open the chuck jaws and remove the
hex key.
