CHUCKREMOVAL
See Figures 10, 11, and 12.
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 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 10. This will loosen the screw in the chuck for easy removal.

The chuck may become loose on 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, follow these steps:
•Lock the switch trigger by placing the direction of rotation selector in center position.
•Insert allen wrench into chuck and tighten chuck jaws securely. Tap allen wrench sharply with a mallet in a clockwise direction. This will tighten chuck on the spindle.
•Open the chuck jaws and remove allen wrench.
•Tighten the chuck screw. Note: The chuck screw has left hand threads.
