Switching On and Off
– To start the machine, press the On/Off
switch 6.
– To lock the On/Off switch, keep it pressed
and additionally push the lock-on button 5.
– To switch off the machine, release the
On/Off switch 6. When the On/Off switch 6
is locked, press it first and then release it.
Setting the Speed/Impact Rate
The speed/impact rate of the switched on pow-
er tool can be variably adjusted, depending on
how far the On/Off switch 6 is pressed.
Light pressure on the On/Off switch 6 results in
low speed/impact rate. Further pressure on the
switch increases the speed/impact rate.
Safety Clutch
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.
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
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.
Bosch Power Tools
Inserting Screwdriver Bits (see figure K)
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 20 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 20 out of the tool
holder.
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.
