Dust/Chip Extraction
Dusts from materials such as lead-containing
coatings, some wood types, minerals and
metal can be harmful to one's health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in
connection with wood-treatment additives
(chromate, wood preservative). Materials
containing asbestos may only be worked by
specialists.
– Provide for good ventilation of the work-
ing 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 5
and keep it depressed.
To lock the pressed On/Off switch 5, press the
lock-on button 4.
To switch off the machine, release the On/Off
switch 5 or when it is locked with the lock-on
button 4, briefly press the On/Off switch 5 and
then 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 Impact Rate
You can set the impact rate of the switched on
power tool continuously, depending on how far
you press down the On/Off switch 5.
Slight pressure on the On/Off switch 5 causes a
low impact rate. Stronger pressure increases
the impact rate.
Changing the Chiselling Position (Vario-Lock)
The chisel can be locked in 12 positions. In this
manner, the optimum working position can be
set for each application.
Insert the chisel into the tool holder.
Push the chisel adjustment ring 3 forward and
turn the chisel to the required position with the
chisel adjustment ring 3.
Release the chisel adjustment ring 3 and turn
the chisel until it latches.
Maintenance and Service
Maintenance and Cleaning
Before any work on the machine itself, pull
the mains plug.
For safe and proper working, always keep
the machine and ventilation slots clean.
A damaged dust protection cap should be
changed immediately. We recommend hav-
ing this carried out by an after-sales serv-
ice.
Lubrication
The power tool is oil-lubricated. An oil change is
required only within the scope of maintenance
or repair through an authorised after-sales serv-
ice agent for Bosch power tools. In this, it is ab-
solutely required to use the specified Bosch oil.
If the machine should fail despite the care taken
in manufacturing and testing procedures, repair
should be carried out by an after-sales service
centre for Bosch power tools.
In all correspondence and spare parts order,
please always include the 10-digit article
number given on the type plate of the machine.
