Safety Clutch
If the tool insert becomes caught or jammed, the drive
to the drill spindle is interrupted. Because of the forces
that occur, always hold the power tool firmly with both
hands and provide for a secure stance.
If the power tool jams, switch the machine off and loos-
en the tool insert. When switching the machine on with
the drilling tool jammed, high reaction torques can oc-
cur.
Working Advice
Before any work on the machine itself, pull the mains
plug.
Changing the Chiselling Position (Vario-Lock)
The chisel can be locked in 12 positions. In this manner, the
optimum working position can be set for each application.
– Insert the chisel into the tool holder.
– Turn the mode selector switch 3 to the "Vario-Lock" posi-
tion (see "Setting the Operating Mode", page 13).
– Turn the tool holder to the desired chiselling position.
– Turn the mode selector switch 3 to the "chiselling" posi-
tion. The tool holder is now locked.
The mode selector switch 3 must always be locked in
the "Chiselling" position when chiselling.
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 machine should fail despite the care taken in manufac-
turing and testing procedures, repair should be carried out by
an after-sales service centre for Bosch power tools.
In all correspondence and spare parts order, please always in-
clude the 10-digit article number given on the type plate of
the machine.
