Always release the variable speed switch
and wait until the motor has come to a
complete standstill before changing the
direction of rotation.
Two gear selector (fig. C)
Your tool is fitted with a two gear selector (3) to vary
the speed/torque ratio.
1 low speed/high torque
(drilling large holes or driving large screws)
2 high speed/low torque
(smaller holes, drilling in wood)
For speed rates, refer to the technical data.
Always push the two gear selector
completely forward or completely back.
Do not change gears at full speed or
during use.
Removing and fitting the chuck (fig. E & F)
• Open the chuck jaws as far as possible.
• Tighten an Allen key (14) into the chuck and
strike it with a hammer as shown in figure E.
• Insert a screwdriver into the chuck and remove
the chuck retaining screw by turning clockwise.
• Tighten an Allen key (14) into the chuck and
strike it with a hammer as shown in figure F.
This will loosen the chuck so that it can be
unscrewed by hand.
• To refit the chuck, proceed in reverse order.
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.
Prior to operation:
• Insert the appropriate bit.
• Mark the spot where the hole is to be drilled.
• Make sure your battery pack is (fully) charged.
• Select forward or reverse rotation.

The pressure exerted on the variable speed switch
determines the tool speed.
• To stop the tool, release the variable speed
switch (1).
• To lock the tool in OFF-position, move the
forward/reverse slider (2) to the central position.
Screwdriving (fig. C & D)
• Select forward or reverse rotation using the
slider (2).
• Use the low speed/high torque position
(1st gear) (3).

the number on the collar, the higher the torque
and the larger the fastener which can be driven.
