– Position the the guide pipe 18 of the dust ex-
traction attachment in its holding fixture in
such a manner that the head of the dust ex-
traction attachment faces against the surface
to be drilled. Do not slide the guide pipe 18
further over the telescopic pipe 16 of the
dust extraction attachment than required, so
that as much as possible of the scale 16 on
the telescopic pipe remains visible.
– Retighten the wing bolt 17 again. Loosen the
clamping screw 14 on the depth stop of the
dust extraction attachment.
– Move the depth stop 15 on the telescopic
pipe 16 in such a manner that the
clearance X shown in the figure corresponds
with the required drilling depth.
– Tighten the clamping screw 14 in this posi-
tion.
Operation

Starting Operation

Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V
can also be operated with 220 V.
Setting the Operating Mode
The operating mode of the power tool is select-
ed with the mode selector switch 7.
Note: Change the operating mode only when the
machine is switched off! Otherwise, the ma-
chine can be damaged.
– Turn the mode selector switch 7 to the de-
sired position until it can be heard to latch.

Reversing the Rotational Direction
(see figure J)
The rotational direction switch 6 is used to re-
verse the rotational direction of the machine.
However, this is not possible with the On/Off
switch 5 actuated.
Right rotation: Push the rotational direction
switch 6 rightward to the stop.
Left rotation: Push the rotational direction
switch 6 leftward to the stop.
Set the direction of rotation for hammer drilling,
drilling and chiselling always to right rotation.
Switching On and Off
– To start the machine, press the On/Off
switch 5.
– To lock the On/Off switch 5, keep it pressed
and additionally push the lock-on button 4.
– To switch off the machine, release the
On/Off switch 5. When the On/Off switch 5
is locked, press it first and then release it.
Setting the Speed/Impact Rate
The speed/impact rate of the switched on pow-
er tool can be variably adjusted, depending on
how far the On/Off switch 5 is pressed.
Light pressure on the On/Off switch 5 results in
low speed/impact rate. Further pressure on the
switch increases the speed/impact rate.
