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. ce-
ramic bonded corundum wheel) with a steady supply of 
water. Reference values are shown in the figure. Take care 
that no annealing coloration appears on the cutting edges; 
this impairs the hardness of the chiselling tools.

– For 

forging

, heat the chisel to between 850 and 1 050 ° 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.

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 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.
