OPERATION
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 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.
■Open chuck jaws and remove allen wrench. Remove 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 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.
TO RETIGHTEN A LOOSE CHUCK
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.
