wise direction. See Figure 9. This will loosen the screw in

ection.See Figure 10. This will loosen chuck on the

wobble when using the drill. Periodically check chuck screw
for tightness. A loose screw may cause the chuck jaws to
bind and prevent them from closing. To tighten, follow these
steps:
1. Unplug the drill.
2. Open the chuck jaws.
3. Insert the hex key wrench into the chuck and tighten the
chuck jaws securely. Tap the hex key sharply with a mal-
let in a clockwise direction.
See Figure 9. This will tighten
the chuck on the spindle.
4. Open the chuck jaws and remove the hex key wrench.
5. Tighten the chuck screw.
Note: The chuck screw has left hand threads.

ply when you are assembling parts, making adjust-

the tool is not in use. Disconnecting the tool will pre-
vent accidental starting that could cause serious in-
