opening is slightly larger than the shank of the bit you
intend to use.

NOTICE: 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 shown in Fig. 9b.
This could cause the drill bit to be thrown from the drill/
driver, resulting in possibly serious personal injury or
damage to the chuck.

center lock position.

WARNING
• Do not hold the chuck body with one hand and use the
power of the drill/driver to tighten or loosen the chuck jaws on the drill bit. The chuck body could
slip in your hand, or your hand could slip and come in contact with the rotating bit. This could
cause an accident resulting in serious personal injury.
