ASSEMBLY & OPERATION
RETIGHTENING LOOSE CHUCK
After installing the chuck once it has been
removed, 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 the chuck, follow these
steps:
1. Insert hex key into chuck and tighten
chuck securely.
2. Tap hex key sharply with a mallet in a
CLOCKWISE direction (see Fig. 10 on
Page 15). This will tighten the chuck on
the spindle.
3. Open chuck jaws and remove the hex
key.
4. Tighten the chuck screw using a #2
Philips screwdriver.
NOTE: Turn screw COUNTER-
CLOCKWISE to tighten it. This screw
has a left hand thread.
