INSTALLING BITS
See Figure 5 - 6.

Unplug the drill.
 Open or close the chuck jaws to a point where the open-
ing is slightly larger than the bit size you intend to use.
Also, raise the front of the drill slightly to keep the bit from
falling out of the chuck jaws.
 Insert the drill bit.
WARNING:
Make sure to insert the drill bit straight into the
chuck jaws. Do not insert the drill bit into the chuck
jaws at an angle then tighten, as shown in figure 6.
This could cause the drill bit to be thrown from the
drill, resulting in possible serious personal injury or
damage to the chuck.
 Tighten the chuck jaws securely on the bit.
NOTE: Rotate the chuck body in the direction of the arrow
marked
LOCK to tighten the chuck jaws. Do not use a
wrench to tighten or loosen the chuck jaws.
