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. 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 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.
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.
