away and never allow ventilation holes to become blocked.
Use a soft brush or dry cloth to clean the machine. If
available, blow through the ventilation holes with clean, dry,
compressed air.

Chuck replacement

The chucks of reversible drills are always fixed by a screw
with a left-hand thread. The screw, which is located in the
centre of the chuck, must be removed before the chuck can
be removed. To remove the screw, turn it in a clockwise
direction. The chuck can now be removed by unscrewing it
anti-clockwise. If you have trouble removing the chuck, take
the drill to your nearest authorised service centre for chuck
replacement.

original packaging. In this way you will always have all
the information and parts ready to hand.
