4. Inspect the mating surfaces on the end of the spindle and the back of the chuck for
burrs or foreign matter. Clean and deburr these areas as necessary.
Installing and Adjusting the chuck
1. Make sure that the cams are aligned in the unlocked position and slide the chuck
onto the spindle.
2. Turn each cam clockwise to lock the chuck in place.
3. Each cam should turn between 140o to 180o of a turn to lock correctly. See the dia-
gram below.
4. If the cam turns less than one fourth of a turn, it will be necessary to remove the
chuck and adjust the corresponding chuck stud.
5. Before removing the chuck, mark each location
on the chuck
that will need
adjusting.
6. Remove the chuck and place it face down on a work surface.
7. There is a locking screw along side each chuck stud. Remove the locking screws for
the studs that need adjusting.
8. Unscrew the studs one turn and install the locking screws.
