Chuck removal
The chucks of reversible drills are always fixed by a screw
with left-hand thread. The screw, which is located in the
centre of the chuck, must be removed before the chuck can
be removed.
1. Tighten the chuck around the shorter end of a hex key
(not supplied) of 1/4” or greater size. Using a wooden
mallet or similar object, strike the longer end in the
clockwise direction. This will loosen the screw inside
the chuck.
2. Open chuck jaws fully.
3. Insert a screwdriver into front of chuck between jaws to
engage screw head. Remove screw by turning clockwise.
4. Place a hex key in chuck and
tighten. Using a wooden mallet or
similar object, strike key sharply
in the counter clockwise direction.
This will loosen the chuck so that
it can be unscrewed by hand.
Chuck installation

screw (LH thread).

around the shorter end
of a 1/4” or large hex
key (not supplied) strike

the chuck firmly.
