• Place the bit in the chuck as far as it will go and
lift slightly before tightening.
• Tighten firmly by turning the sleeve clockwise.
• To remove the bit, proceed in reverse order.
Selecting the operating mode or adjusting the
torque (fig. D)
The collar of this tool has 15 positions for the
adjustment of the torque to suit the size of the screw
and the workpiece material. For torque adjustment,
refer to the section „Screwdriving".
• Select the drilling mode or torque by aligning the
symbol or number on the collar (5) with the
indicator (15) on the housing.
Forward/reverse slider (fig. E)
• To select forward or reverse rotation, use the
forward/reverse slider (2) as shown (see arrows
on tool).
Always wait until the motor has come to
a complete standstill before changing the
direction of rotation.
Two gear selector (fig. F)
Your tool is fitted with a two gear selector (6) to vary
the speed/torque ratio.
1 low speed/high torque (drilling large holes, driving
screws)
2 high speed/low torque (drilling smaller holes)
For speed rates, refer to the technical data.
• Always push the two gear selector
completely forward or backward.
• Do not change gears at full speed or
during use.
Instructions for use
Always observe the safety instructions
and applicable regulations.
Be aware of the location of pipework and

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.
