Dust Extraction with the Extraction Device
(Accessory)
Dusts from materials such as lead-containing coat-
ings, some wood types, minerals and metal can be
harmful to one's health. Touching or breathing-in
the dusts can cause allergic reactions and/or lead to
respiratory infections of the user or bystanders.
Certain dusts, such as oak or beech dust, are con-
sidered as carcinogenic, especially in connection
with wood-treatment additives (chromate, wood pre-
servative). Materials containing asbestos may only
be worked by specialists.
• Provide for good ventilation of the working place.
• It is recommended to wear a P2 filter-class respi-
rator.
Observe the relevant regulations in your country for
the materials to be worked.
Mounting the Extraction Device
(see figure F)
An extraction device (accessory) is required for dust
extraction. When drilling, the extraction device
retracts so that the head of the extraction device is
always positioned close to the surface.
Press the button for depth stop adjustment 9 and
remove the depth stop 11. Press button 9 again and
insert the extraction device from the front into the
auxiliary handle 10.
Connect a vacuum hose to the extraction sleeve 15
of the extraction device.
The vacuum cleaner must be suitable for the mate-
rial being worked.
When vacuuming dry dust that is especially detri-
mental to health or carcinogenic, use a special vac-
uum cleaner.
Adjusting the Drilling Depth on the
Extraction Device (see figure G)
The requested drilling depth X can also be set when
the extraction device is mounted.
Insert the SDS-plus drilling tool to the stop into the
SDS-plus tool holder 1. Otherwise, the movability of
the SDS-plus drilling tool can lead to incorrect
adjustment of the drilling depth.
Loosen wing bolt 19 of the extraction device.
Without switching the power tool on, apply it firmly
to the drilling location. The SDS-plus drilling tool
must face against the surface.
3.3.09
Move the guide tube 20 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 20 further over the telescopic
pipe 18 than necessary, so that as much as possible
of the scale remains visible on the telescopic pipe
18.
Tighten wing bolt 19 again. Loosen clamping screw
16 at the depth stop of the extraction device.
Move the depth stop 17 on the telescopic pipe 18 in
such a manner that the clearance X shown in the fig-
ure corresponds with the required drilling depth.
Tighten the clamping screw 16 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 5.
☞
Note: Change the operating mode only
when the machine is switched off! Otherwise,
the machine can be damaged.
Turn the mode selector switch 5 to the requested
position.
Position for drilling without
impact in wood, metal,
ceramic and plastic
Position for hammer drill-
ing in concrete or stone
When the drilling tool does
not immediately rotate upon
switching on, allow the
machine to run slowly until
the drilling tool rotates.
Position for changing the
position of the chisel
Position for chiselling
