• Open the chuck jaws as far as possible.
• Insert a screwdriver into the chuck and remove
the chuck retaining screw by turning clockwise
as shown in figure F.

with a hammer as shown in figure G. This will

Instructions for use
• Always observe the safety instructions
and applicable regulations.
• Be aware of the location of pipework
and wiring.
• Apply only a gentle pressure to the tool.
Excessive force does not speed up
drilling but decreases tool performance
and may shorten tool life.
• To minimise stalling on break-through,
progressively reduce the drill point
pressure towards the end of the operation.
• Keep the motor running when pulling the
bit back out of a drilled hole. This will
help prevent jamming.
Prior to operation:
• Make sure your battery pack is (fully) charged.
• Insert the appropriate bit.
• Mark the spot where the hole is to be drilled.
• Select forward or reverse rotation.
Switching ON and OFF (fig. A & D)
