CHUCK REMOVAL
See Figures 13, 14, and 15.
The chuck must be removed in order to use some
accessories. To remove:
Lock the switch trigger by placing the direction of rotation
selector in center position.
Insert a 5/16 inch or larger hex key wrench into the chuck
of your drill and tighten the chuck jaws securely.
Tap the hex key wrench sharply with a mallet in a
clockwise direction.

This will loosen the
screw in the chuck for easy removal.
Open chuck jaws and remove hex key wrench. Remove
the chuck screw by turning it in a clockwise direction.
See Figure 14.
Note: The screw has left hand threads.
Insert hex key wrench in chuck and tighten chuck jaws
securely. Tap sharply with a mallet in a counterclockwise
direction. This will loosen chuck on the spindle. It can
now be unscrewed by hand.
See Figure 15.

selector in center position.
Insert hex key wrench into chuck and tighten chuck jaws
securely. Tap hex key wrench sharply with a mallet in a
clockwise direction. This will tighten chuck on the spindle.
