Single Sleeve Keyless Chuck
(Fig. 7, 8, & 9)
These tools are equipped with a spindle-
lock mechanism and a single-sleeve key-
less chuck. Always unplug the tool before
inserting or removing bits.
1. To open the chuck jaws, turn the chuck
sleeve counterclockwise (Fig. 7).
Be sure the bit shank and chuck jaws
are clean. Dirt particles may prevent
the bit from lining up properly.
2. When using drill bits, insert the bit into
the chuck. Center the bit in the chuck
jaws and lift it about 1/16" off of the
bottom. Tighten the chuck jaws by hand
to align the bit (Fig. 5).
Be sure the bit shank and chuck jaws
are clean. Dirt particles may prevent
the bit from lining up properly.
2. When using drill bits, insert the bit into
the chuck. Center the bit in the chuck
jaws and lift it about 1/16" off of the
bottom. Tighten the chuck jaws by hand
to align the bit (Fig. 8).
When using screwdriver bits, insert the
bit far enough for the chuck jaws to
grip the bit shank. Tighten the chuck
jaws by hand to align the bit.
3. To close the chuck jaws, turn the chuck
sleeve clockwise (Fig. 9). Tighten se-
curely. Several detents will be felt as
the chuck sleeve is turned.
When using screwdriver bits, insert the
bit far enough for the chuck jaws to
grip the bit shank. Tighten the chuck
jaws by hand to align the bit.
3. To close the chuck jaws, hold the collar
and turn the sleeve clockwise
(Fig. 6). Tighten securely.
4. To remove the bit, hold the chuck collar
and turn the sleeve counterclockwise
to release the bit from the chuck jaws.
NOTE: If the spindle rotates when
opening or closing the chuck jaws,
grasp the chuck and slightly rotate back
and forth to engage the spindle-lock
mechanism.
The spindle will remain locked until the
tool is turned on. The spindle-lock
mechanism will automatically disen-
gage when the tool is turned on.

Chuck Removal (Fig. 7)
This tool is equipped with a threaded spindle
to hold the chuck. Before removing the
chuck, unplug the tool and open the chuck
jaws. A left-handed thread screw is lo-
cated inside the chuck to prevent the chuck
from loosening when the tool is operated
in reverse direction. Remove the screw by
turning it clockwise. To remove the chuck,
hold the tool so that only the side of the
chuck rests firmly and squarely on a solid
workbench. Insert the chuck key or a chuck
remover bar in one of the keyholes. Turn
the chuck so the key is at about a 30° angle
to the bench top and strike the key sharply
with a hammer so the chuck turns in a
counterclockwise direction (looking from
the front of the tool). This should loosen
the chuck from the spindle which has a
right hand thread making it easy to remove
the chuck by hand.
NOTE: When replacing the chuck, always
replace the left hand thread screw in the
chuck.
WARNING!
To reduce the risk of injury,
always wear eye protection.
