Keyless Chuck (fi g. 4–6)
The DWD221 features a keyless chuck (d) for
greater convenience. To insert a drill bit or other
accessory, follow the steps listed below.
1. Grasp the rear half of the chuck with one hand
and use your other hand to rotate the front half
counterclockwise, as shown in Figure 4. Rotate
far enough so that the chuck opens sufficiently
to accept the desired accessory.
2. Insert the bit or other accessory about 3/4"
(19 mm) into the chuck and tighten securely
by holding the rear half of the chuck and
rotating the front portion in the clockwise
direction. When the chuck is nearly tightened,
you will hear a clicking sound. After 4–6 clicks,
the chuck is securely tightened around the
accessory.
3. To release the accessory, repeat step 1 listed
above.
WARNING: Do not attempt to tighten
or loosen drill bits (or any other
accessory) by gripping the front part
of the chuck and turning the tool on.
Damage to the chuck and personal
injury may occur.
KEYLESS CHUCK REMOVAL (FIG. 5)
Tighten the chuck around the shorter end of a hex
key (not supplied) of 1/4" (6 mm) or greater size.
Using a soft hammer or piece of wood, strike the
longer end in the counterclockwise direction. This
will loosen the chuck so that it can be unscrewed
by hand.
KEYLESS CHUCK INSTALLATION (FIG. 6)
Screw the chuck on by hand as far as it will go.
Tighten the chuck around the shorter end of a 1/4"
(6 mm) or larger hex key (not supplied). Strike the
