Operation
Starting operation
u
Pay attention to the mains voltage. The voltage of the
power source must match the voltage specified on the
rating plate of the power tool. Power tools marked
with 230 V can also be operated with 220 V.
Switching on/off
– To start the power tool, tilt the on/off switch (2) to the " I "
position.
– To switch off the power tool, tilt the on/off switch (2) to
the " 0 " position.
At low temperatures, the power tool will take a certain
amount of time to reach its full impact performance. You can
shorten this warm-up time by tapping the power tool's inser-
ted application tool on the ground once.
Working advice
u
Pull the plug out of the socket before carrying out any
work on the power tool.
While working, hold the power tool with both hands by the
handle
(1) . The handle (1) can move up and down around its
axis by approx. 30 mm. This has a damping effect against vi-
brations.
For the highest possible impact damping, work only with
moderate pressure.
Sharpening Chisels
Only sharp chiselling tools will produce good results, there-
fore sharpen your chiselling tools in good time before use.
This will ensure a long service life for the tools and good
work results.
Resharpening
Grind chiselling tools against sanding discs, e.g. aluminium
oxide, under a steady stream of water. Take care that no an-
nealing colouration appears on the cutting edges; this im-
pairs the hardness of the chiselling tools.

To forge a chisel, heat it to between 850 and 1050 °C (pale
red to yellow).
To
harden a chisel, heat it to approx. 900 °C and quench in
oil. Then, leave it in an oven for approx. one hour at 320 °C
(annealing colour: pale blue).
Maintenance and Service
Maintenance and Cleaning
u
Pull the plug out of the socket before carrying out any
work on the power tool.
u
To ensure safe and efficient operation, always keep
the power tool and the ventilation slots clean.
In order to avoid safety hazards, if the power supply cord
needs to be replaced, this must be done by
Bosch or by an
after-sales service centre that is authorised to repair Bosch
power tools.
When the carbon brushes are worn out, the power tool
switches itself off. The power tool must be sent to the after-
sales service for maintenance; see the "After-sales service
and application service" section for addresses.
