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 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).
