INSTALLING & REMOVING ACCESSORIES

3-JAW CHUCK

For small bits, open jaws enough to insert the bit up to the flutes. For large bits, insert the bit as far as it will go. Center the bit as you close the jaws by hand. This positions the bit properly, giving maximum contact between the chuck jaws and the bit shank (Fig. 6).

To tighten chuck, insert key into each of the three key holes in succession and tighten clockwise firmly.

The chuck can be released by using one hole only.

Note: The 3-Jaw Chuck is for use only in “Drill only” mode. The 3-Jaw Chuck is not for use when drilling with hammering action.
