OPERATING INSTRUCTIONS
INSTALLING BITS (Fig. 11)
1. Lock the trigger switch by placing the direction-of-
rotation selector ( B ) in the OFF (center) position.
2. Open or close the chuck jaws to a point where the
opening is slightly larger than the shank of the bit you
intend to use.
3. Insert the bit.
4. Tighten the chuck jaws securely on the bit.
NOTE: Rotate the chuck body in the direction of the
arrow marked GRIP to close the chuck jaws. Do not use
a wrench to tighten or loosen the chuck jaws.
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 and then tighten the chuck as

thrown from the drill/driver, resulting in possibly serious
personal injury or damage to the chuck.

WARNING: Always wear safety goggles or safety
glasses with side shields during power tool operation or
when blowing dust. If operation is dusty, also wear a dust
