Drilling wood

•Clamp a piece of scrap wood to the back of your work to prevent splintering.

All drilling operations

•Mark off the centre of the hole using a centre punch or nail.

•Don’t force the drill, let it work at its own pace

•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 power tool repair 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.
