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.
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 8).
– 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.

Working Advice

 Before any work on the machine itself, pull the mains
plug.
Vibration Damper
The integrated vibration damper reduces occurring vibra-
tions.
The soft grip handle increases the safety against slipping off
and thus provides for a better grip and handling of the power
tool.

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.
Bosch Power Tools
If the replacement of the supply cord is necessary, this has to
be done by Bosch or an authorized Bosch service agent in or-
Thumbwheel
der to avoid a safety hazard.
Position
Service Indicator 8
When the carbon brushes are worn out, the machine switches
itself off. This is indicated approx. 8 hours beforehand by the
lighting or blinking of the service indicator 8. The machine
must then be sent to an after-sales service agent. Addresses
are listed in the Section "After-sales Service and Application
Service".
Stand-by Indicator 9
When the mains plug is plugged in and mains voltage is given,
the stand-by indicator 9 must be lit. When the machine can-
not be switched on despite lit stand-by indicator 9, it must be
sent to an after-sales service agent; for addresses, see sec-
tion "After-sales Service and Application Service", page 9.
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.
