Move the guide tube 23 of the extraction device in its
holder in such a manner that the head of the extrac-
tion device faces against the surface to be drilled. Do
not move guide tube 23 further over the telescopic
pipe 21 than necessary, so that as much as possible
of the scale remains visible on the telescopic pipe
21.
Tighten wing bolt 22 again. Loosen clamping screw
19 at the depth stop of the extraction device.
Move the depth stop 20 on the telescopic pipe 21 in
such a manner that the clearance X shown in the fig-
ure corresponds with the required drilling depth.
Tighten the clamping screw 19 in this position.
Starting Operation
❏ Observe correct mains voltage! The volt-
age 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 selected
with the mode selector switch 11.
To change the operating mode, push the release
button 10 and turn the mode selector switch 11 to
the requested position until it can be heard to latch.
☞
Note: Change the operating mode only
when the machine is switched off! Otherwise,
the machine can be damaged.
Position for hammer drilling in
concrete or stone
Position for drilling without impact
in wood, metal, ceramic and plastic
Position for changing the position
of the chisel
The mode selector switch 11 does
not latch in this position.
Position for chiselling
Reversing the Rotational Direction
The rotational direction switch 7 is used to reverse
the rotational direction of the machine. However,
this is not possible with the On/Off switch 9 actu-
ated.
16–English
Right rotation: Turn the selector switch for drill-
ing/hammer drilling 7 on both sides to the stop
in the position .
Left rotation: Turn the selector switch for drill-
ing/hammer drilling 7 on both sides to the stop
in the position .
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 9.
To lock the On/Off switch, keep it pressed and
additionally push the lock-on button 8.
To switch off the machine, release the On/Off
switch 9. When the On/Off switch 9 is locked, press
it first and then release it.
Setting the Speed/Impact Rate
The speed/impact rate of the switched on power tool
can be variably adjusted, depending on how far the
On/Off switch 9 is pressed.
Light pressure on the On/Off switch 9 results in low
speed/impact rate. Further pressure on the switch
increases the speed/impact rate.
Safety Clutch
❏ If the tool insert becomes caught or
jammed, the drive to the drill spindle is
interrupted. Because of the forces that
occur, always hold the power tool firmly
with both hands and provide for a secure
stance.
❏ If the power tool jams, switch the machine
off and loosen the tool insert. When
switching the machine on with the drilling
tool jammed, high reaction torques can
occur.
Working Advice
Changing the position of the chisel
The chisel can be locked in 36 positions. In this man-
ner, the optimum working position can be set for
each application.
Insert the chisel into the tool holder.
Turn the mode selector switch 11 to the requested
position.
Turn the tool holder to the desired chiselling posi-
tion.
Turn the mode selector switch 11 to the "chiselling"
position. The tool holder is now locked.
For chiselling, set the rotation direction to right rota-
tion.
