INSTALLING DRILL BITS
WARNING: Never hold the
chuck body with one hand and
use the drill power to rotate the
drill body to loosen or tighten
bits. Serious injury may result.
1. Remove the hammer drill plug
from the power source.
2. Rotate chuck collar (1) in a
counter clockwise direction until the
chuck jaws (2) open wide enough to
accept the bit (3) (Fig. 3).
3. Insert the bit into the chuck the full
length of the jaws or until the spiral
portion of the bit is near the chuck
jaws. Raise the front of your drill
slightly to prevent the bit from falling
out of the chuck jaws.
4. Tighten the chuck jaws onto the
bit by turning the chuck
NOTE: Make sure the bit is properly
aligned in the jaws and NOT at an
angle. An improperly aligned bit
could be thrown from the chuck
when the drill is started.
5. Finish tightening the chuck jaws
by inserting the chuck key (4) into
one of three holes (5) in the chuck
body. Rotate chuck key clockwise
until drill bit is held firmly in place by
the chuck jaws.
NOTE: Do NOT use a wrench or
pliers on the chuck key. You may
damage the key or the chuck (4).
