Inserting (see figure A)

Removing (see figure B)

Dust/Chip Extraction
 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 reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dust, such as oak or beech dust, is considered car-
cinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials con-
taining 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 pow-
er 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 pressed.
– 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 ham-
mer/impact capacity only after a certain time.
To save energy, only switch the power tool on when using it.
Setting the Impact Rate
You can set the impact rate of the switched on power tool con-
tinuously, 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 un-
til 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 im-
mediately. We recommend having this carried out by
an after-sales service.
If the replacement of the supply cord is necessary, this has to
be done by Bosch or an authorized Bosch service agent in or-
der to avoid a safety hazard.
Lubrication
The power tool is oil-lubricated. An oil change is required only
within the scope of maintenance or repair through an author-
ised after-sales service agent for Bosch power tools. In this, it
is absolutely required to use the specified Bosch oil.
