Chuck Removal
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 located inside the chuck to prevent the chuck from
loosening when the tool is operated in reverse direc-
tion. 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. In
-
sert 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 coun-
terclockwise 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.
