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.
