Dust/Chip Extraction

Dusts 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 dusts can cause allergic reac-
tions and/or lead to respiratory infections of the
user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in con-
nection with wood-treatment additives (chro-
mate, wood preservative). 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
respirator.
Observe the relevant regulations in your country
for the materials to be worked.
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.
Switching On and Off
– To start the machine, press the On/Off
switch 6 at the top (I) until it locks.
– To switch off the machine, press the On/Off
switch 6 at the bottom (0) and release it.
For low temperatures, the power tool reaches
the full hammer/impact capacity only after a cer-
tain time.
Bosch Power Tools
Setting the Speed/Impact Rate
The electronic control enables stepless speed
and impact preselection in accordance with the
material to be worked.
The constant electronic control keeps the prese-
lected speed and impact rate nearly constant
between no-load and load conditions.
Select the speed with the thumbwheel 7 accord-
ing to the material.
When plugging the plug into the socket outlet or
after a power failure, the constant electronic
control automatically sets the highest speed
and impact rate. This ensures working at opti-
mum performance despite too low preadjust-
ment of the thumbwheel 7.
The data in the following table are recommend-
ed values.

– Push the chisel adjustment ring 3 forward
and turn the chisel to the required position
with the chisel adjustment ring 3.
