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 counterclockwise direction. This will loosen the chuck so that it can be unscrewed by hand.

Chuck installation

2.Tighten the chuck around the shorter end

of a 1/4” or large hex key (not supplied) strike the longer end in the clockwise direction with a wooden mallet.
