CAUTION
INSERTING BIT
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.
To tighten, hold the chuck collar firmly with one
hand and securely tighten the chuck sleeve
with the other hand (Fig. 2).
To prevent friction burns, or
pos sible hand injury, do not
loosen or tighten the chuck by using the power
of the drill.

Open the chuck all the way, remove left-hand
thread screw inside chuck by turning it
clockwise (Fig. 3).

and close jaws on flats of wrench (Fig. 4).
Strike long arm of wrench sharply counter-
clockwise, remove wrench and unthread chuck
from spindle.
INSTALLING CHUCK
Always keep the spindle threads, the threads
of the chuck and securing screw free of debris.
