INSTALLING AND REMOVING DRILL BITS

Disconnect tool from power source!

1.The three-jaw chuck is designed for self-centering of the drill bit. Open the jaws by turning the outer sleeve counter-clockwise (when viewing the chuck from the bit end), so that bit shank can be inserted easily.

2.Clean and insert the smooth end of the drill bit into the chuck as far as it will go, then back it out approximately 1/16", or up to the flutes for small bits.

3.While holding the bit with one hand, turn the outer sleeve clockwise until the chuck grips the bit.

4.Tighten the chuck – insert the chuck key into each of 3 keyholes in the chuck body (Fig. 1) and tighten each securely by turning the key clockwise.

Remove the chuck key before starting the tool.

5.To remove the bit, reverse the procedure.
