CHUCK REMOVAL
See Figures 10, 11, and 12.
Whenever necessary to remove the chuck for replacement, etc., use the following procedure for chuck removal:
1.UNPLUG YOUR DRILL.
WARNING:
Failure to unplug your drill could result in accidental starting causing serious injury.
2.Open chuck jaws. Insert a 5/16 inch or larger hex key wrench (allen wrench) into the chuck of your drill and tighten the chuck jaws securely.
3.Tap the hex key wrench sharply with a mallet in a clockwise direction. See Figure 10. This will loosen the chuck screw for removal.
4.Open the chuck jaws and remove hex key wrench. Remove the chuck screw by turning it in a clockwise direction. See Figure 11.
NOTE: The chuck screw has left hand threads.
5.Insert hex key wrench in chuck and tighten chuck jaws securely. Tap sharply with a mallet in a counterclock- wise direction. This will loosen the chuck on the spindle. It can now be unscrewed by hand. See Figure 12.
