Dust Extraction (Accessory)
 Dust from materials such as lead-containing
coatings, some wood types, minerals and metal
can be harmful to one's health. Touching or
breathing-in the dust can cause allergic reac-
tions and/or lead to respiratory infections of the
user or bystanders.
Certain dust, such as oak or beech dust, is con-
sidered carcinogenic, especially in connection
with wood-treatment additives (chromate, wood
preservative). Materials containing asbestos may
only be worked by specialists.
– As far as possible, use a dust extraction sys-
tem suitable for the material.
– Provide for good ventilation of the working
place.
– It is recommended to wear a P2 filter-class res-
pirator.
Observe the relevant regulations in your country
for the materials to be worked.
 Prevent dust accumulation at the workplace.
Dust can easily ignite.
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.
Operation
Starting Operation
Inserting the battery
– Set the rotational direction switch 8 to the centre
position to protect the power tool against acci-
dental starting.
– Insert the charged battery pack 11 from the rear
into the base of the power tool. Press the battery
pack completely into the base until the red stripe
can no longer be seen and the battery pack is se-
curely locked.
Setting the operating mode
The operating mode of the power tool is selected
with the mode selector switch 13.
Note: Change the operating mode only when the
machine is switched off! Otherwise, the machine
can be damaged.
– To change the operating mode, push the release
button 12 and turn the mode selector switch 13
to the requested position until it can be heard to
latch.
20 | English
Position for hammer drilling in con-
crete or stone
Position for drilling without impact in
wood, metal, ceramic and plastic as
well as for screwdriving
Vario-Lock position for adjustment
of the chiselling position
The mode selector switch 13 does
not latch in this position.
Position for chiselling
Reversing the rotational direction
The rotational direction switch 8 is used to reverse
the rotational direction of the machine. However,
this is not possible with the On/Off switch 10 actu-
ated.
Right rotation: Move the rotational direction switch
8 all the way to position
Left rotation: Move the rotational direction switch
8 all the way to position
Set the direction of rotation for hammer drilling,
drilling and chiselling always to right rotation.
Switching On and Off
To save energy, only switch the power tool on
when using it.
– To start the machine, press the On/Off switch
10.
When starting the machine for the first time, a start-
ing delay is possible, as the electronic system of
the power tool has to configure itself first.
– To switch off the machine, release the On/Off
switch 10.
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 10 is pressed.
Light pressure on the On/Off switch 10 results in
low speed/impact rate. Further pressure on the
switch increases the speed/impact rate.
Electronic Precision Control (EPC) (see figure I)
EPC assists you when working with impact in sen-
sitive materials by ensuring slow start-up and re-
duced operating speed.
– Slide the EPC switch 26 to the desired position.
