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, push the On/Off switch 

2

 to the “

I

” 

position.

– To 

switch off

 the machine, push the On/Off switch 

2

 to the 

“

0

” position.

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.

To save energy, only switch the power tool on when using it.

Working Advice (see figure G)



Before any work on the machine itself, pull the mains 
plug.

While working, hold the power tool with both hands by the 
handle 

1

. The handle 

1

 can move upward and downward 

around its axis by approx. 30 mm. This has a damping effect 
against vibrations.

For the highest possible impact damping, work only with 
moderate pressure.

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. Ref-
erence values are shown in the figure. Take care that no an-
nealing coloration appears on the cutting edges; 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.

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.

When the carbon brushes wear below acceptable service tol-
erances, the machine will automatically cut out. The machine 
must be sent to customer service for maintenance (for ad-
dress, see the “After-sales Service and Application Service” 
section.
