CHUCK REMOVAL
See Figures 13, 14, and 15.
The chuck must be removed in order to use some accessories.
To remove:
■

selector in center position.
■
Insert a 5/16 inch or larger allen wrench (hex key wrench)
into the chuck of your drill and tighten the chuck jaws
securely.
■
Tap the allen wrench sharply with a mallet in a clockwise
direction.
See Figure 13. This will loosen the screw in
the chuck for easy removal.
■

the chuck screw by turning it in a clockwise direction.
See Figure 14. Note: The screw has left hand
threads.
■
Insert allen wrench in chuck and tighten chuck jaws

direction. This will loosen chuck on the spindle. It can
now be unscrewed by hand.
See Figure 15.

selector in center position.
■
Insert allen wrench into chuck and tighten chuck jaws
securely. Tap allen wrench sharply with a mallet in a
