The chisel can be locked in 36 positions. In this
manner, the optimum working position can be set
for each application.
Insert the chisel in the tool holder.
Press the release button 5 and turn the mode se-
lector switch 6 at the same time to the “Chisel
(Vario-lock)” position.
Turn the tool holder to the desired chiselling posi-
tion.
Allow the mode selector switch 6 to latch in the
“Chiselling” position. The tool holder is locked in
this position.
The mode selector switch 6 must always be
locked in the “Chiselling” position when chis-
elling.
If the drill becomes caught or jammed, the
drive to the drill spindle is interrupted.
Because of the forces that occur as a result,
always hold the machine securely with both
hands and take a firm stance.
Since good results can be achieved only with
sharp chisels, sharpen the chiselling tools regu-
larly. This prolongs the service life of the tools and
ensures good working performance.
Sharpen chiselling tools using grinding wheels
(e. g., special fused alumina) with a steady supply
of water. Recommended values for this purpose
are contained in figure E. Take care that no an-
nealing coloration appears on the cutting edges,
otherwise the hardness of the chiselling tools will
be impaired.
■
Before any work on the machine itself, pull
the mains plug.
☞
For safe and proper working, always keep
the machine and the ventilation slots clean.
■
Keep the tool holder clean at all times.
If the machine should fail despite the rigorous
manufacturing and testing procedures, repair
should be carried out by an authorised customer
services centre for Bosch power tools.
In all correspondence and spare parts orders,
please always include the 10-digit order number
given on the nameplate of the machine.
