Bosch Power Tools
Safety Clutch
f
If the tool insert becomes caught or
jammed, the drive to the drill spindle is in-
terrupted. Because of the forces that occur,
always hold the power tool firmly with both
hands and provide for a secure stance.
f
If the power tool jams, switch the machine
off and loosen the tool insert. When switch-
ing the machine on with the drilling tool
jammed, high reaction torques can occur.
Working Advice
f
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
7
to the
“Vario-Lock” position (see “Setting the Oper-
ating Mode”, page 23).
– Turn the tool holder to the desired chiselling
position.
– Turn the mode selector switch
7
to the “chis-
elling” position. The tool holder is now
locked.
GBH 2-24 DSR: For chiselling, set the rotation
direction to right rotation.
Inserting Screwdriver Bits (see figure H)
f
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.
Maintenance and Service
Maintenance and Cleaning
f
Before any work on the machine itself, pull
the mains plug.

ing this carried out by an after-sales serv-
ice.

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
