REMOVING THE CHUCK

See Figures 14, 15, and 16.

Follow these steps to remove the chuck.

■ Lock the trigger switch by placing the rotation selec-

tor in the center position.

■ Insert a 5/16 inch or larger hex key wrench into the

chuck of the 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.

wrench.

direction.

the chuck jaws securely.

direction. This will loosen chuck on the spindle. It can

now be unscrewed by hand.

TIGHTENING THE CHUCK

tor in center position.
