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.
