CHUCK REMOVAL
See Figures 11 - 13.
The chuck may be removed and replaced with a new one.
Unplug the drill.
Open chuck jaws using the provided chuck key.
Insert a 5/16 inch or larger hex key into the chuck of the
drill and tighten the chuck jaws securely.
Tap the hex key sharply with a mallet in a clockwise
direction. This will loosen the screw in the chuck for easy 
removal.
Open chuck jaws and remove hex key. Remove the chuck
screw with a screwdriver by turning it in a clockwise 
direction.
NOTE: The screw has left hand threads.
Insert the hex key into the chuck and tighten the
chuck jaws securely. Tap sharply with a mallet in a 
counterclockwise direction. This will loosen the chuck 
on the spindle. It can now be unscrewed by hand. 
TO RETIGHTEN A LOOSE CHUCK
The chuck may become loose on the spindle and de-
velop a wobble. Also, the chuck screw may become loose, 
causing the chuck jaws to bind and prevent them from 
closing. 
To tighten:
Unplug the drill.
Open the chuck jaws.
Insert the hex key into the chuck and tighten the chuck
jaws securely. Tap the hex key sharply with a mallet in 
a clockwise direction. This will tighten the chuck on the 
spindle.
Open the chuck jaws and remove the hex key.
Tighten the chuck screw with a screwdriver.
