KEYLESS
CHUCK
See Figure 11.
A keyless chuck has been provided with your drill to allow
for easy installation and removat of bits. As the name
implies, you can hand tighten or release drill bits in the
chuck jaws. Arrows on the chuck indicate which direction
to rotate the chuck sleeve in order to LOCK (tighten) or
UNLOCK (release) the chuck jaws. Loosen the chuck
sleeve by rotating it counterclockwise with one hand.
Insert drill bit straight into the chuck the full length of the
jaws, and tighten securely by rotating the chuck sleeve in
clockwise direction.
