or nail.

Keep the drill bit sharp.
Reduce pressure, as the drill is about to break through
the item being drilled.
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.
Caution. Always ensure that the drill is switched off
and the battery pack is removed before making any
adjustments.
Maintenance
Store the tools, instruction manual and where necessary
the accessories in the original packaging. In this way
you will always have all the information and parts ready
to hand.
Do not throw used batteries into fire or water. There is
a danger of explosion! Please hand in non-working or
used batteries, or tools with built-in batteries, to the
environmentally-safe disposal unit at a municipal waste-
disposal centre, or to your dealer.
