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 36 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 8 to the
"Vario-Lock" position (see "Setting the Oper-
ating Mode", page 22).
– Turn the tool holder to the desired chiselling
position.
– Turn the mode selector switch 8 to the "chis-
elling" position. The tool holder is now
locked.
For chiselling, set the rotation direction to right
rotation.
Inserting Screwdriver Bits (see figure H)
Apply the power tool to the screw/nut only
when it is switched off. Rotating tool inserts
can slip off.
To work with screwdriver bits, a universal bit
holder 22 with SDS-plus shank (accessory) is re-
quired.
– Clean the shank end of the adapter shank
and apply a light coat of grease.
– Insert the universal bit holder with a turning
motion into the tool holder until it automati-
cally locks.
– Check the locking effect by pulling the uni-
versal bit holder.
– Insert a screwdriver bit into the universal bit
holder. Use only screwdriver bits that match
the screw head.
– To remove the universal bit holder, pull the
locking sleeve 3 toward the rear and remove
the universal bit holder 22 out of the tool
holder.
Bosch Power Tools
Utility Hook (see figure I)
With the utility hook 6, you can hang the power
tool, e.g., to a ladder. For this, open the utility
hook 6 so far that it engages in the open posi-
tion.
Hang up the power tool in such a manner
that it cannot fall down and that the appli-
cation tool is protected against accidental
contact. Danger of injury.
Fold the utility hook 6 back in again when you
are ready to continue working.

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 immediately. We recommend hav-
ing this carried out by an after-sales serv-
ice.
– Clean the tool holder 1 each time after using.
If the machine should fail despite the care taken
in manufacturing 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 include the 10-digit article
number given on the type plate of the machine.
