and develop a wobble. Also, the chuck screw
may become loose, causing the chuck jaws
to bind and prevent them from closing.
To tighten:
1. Unplug the hammer drill.
WARNING:

To prevent personal
injury, ALWAYS disconnect the plug

or changing bits.
2. Open the chuck jaws.
3. Insert a 5/16 in. or larger 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.
4. Open the chuck jaws, and remove the hex key.
5. Tighten the chuck screw. Note that the chuck
screw has left hand threads and counterclockwise direction tightens instead of loosens.
