a wobble. Periodically check chuck screw for tight-
ness. A loose screw may cause the chuck jaws to
bind and prevent them from closing.

• Lock the switch trigger by placing the direction of
rotation selector in center position. See Figure 5.
• Open the chuck jaws.
• Insert hex key wrench into chuck and tighten
chuck jaws securely. Tap hex key wrench sharply
with a mallet in a clockwise direction. This will
tighten chuck on the spindle.
• Open the chuck jaws and remove hex key
wrench.
• Tighten the chuck screw.
