MAINTENANCE
TO RETIGHTEN A LOOSE CHUCK
(Figs. 18 and 18a)
The chuck may become loose on the spindle
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. Lock the trigger switch by placing the
Forward / Reverse Selector Switch with Power
Lock-Off in the center, or OFF position.
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 (see Fig. 18).
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 (see Fig. 18a).
