Removing (see figure B)
– Push back the locking sleeve 2 and remove the tool.
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 reactions 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 connection with wood-treat-
ment additives (chromate, 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 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 4 and keep
it pressed.
– To lock the pressed On/Off switch 4, press the lock-on
button 3.
– To switch off the machine, release the On/Off switch 4 or
when it is locked with the lock-on button 3, briefly press
the On/Off switch 4 and then release it.
For low temperatures, the machine reaches the full impact
rate only after a certain time.
This start-up time can be shortened by striking the chisel in
the machine against the floor one time.
Working Advice
Before any work on the machine itself, pull the mains
plug.
Sharpening Chisels
Good results are only achieved with sharp chisels; therefore,
sharpen the chiselling tools in good time. This ensures a long
service life of the tools and good working performance.
Re-sharpening
Sharpen chiselling tools using grinding wheels (e. g. ceramic
bonded corundum wheel) with a steady supply of water. Take
care that no annealing coloration appears on the cutting edg-
es; this impairs the hardness of the chiselling tools.
For forging, heat the chisel to between 850 and 1050 °C
(bright red to yellow).
For hardening, heat the chisel to approx. 900 °C and quench
in oil. Then anneal in an oven for approx. one hour at 320 °C
(annealing colour = light blue).

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.
Power Tool Lubrication
The power tool is grease-lubricated. Replacement of the lubri-
cating grease is required only during maintenance or repair
through an authorised customer services agent for Bosch
power tools. Here, it is essential that the specified Bosch lu-
bricating grease is used.
If the machine should fail despite the care taken in manufac-
turing 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 in-
clude the 10-digit article number given on the type plate of
the machine.
