Operation

Starting Operation

Inserting the battery
– Set the rotational direction switch 8 to the centre position
to protect the power tool against accidental starting.
– Insert the charged battery 17 from the front into the base
of the power tool. Push the battery completely into the
base until the red stripe can no longer be seen and the bat-
tery is securely locked.
Setting the operating mode
The operating mode of the power tool is selected with the
mode selector switch 11.
Note: Change the operating mode only when the machine is
switched off! Otherwise, the machine can be damaged.
– To change the operating mode, push the release button 10
and turn the mode selector switch 11 to the requested po-
sition until it can be heard to latch.
Position for hammer drilling in concrete or
stone
Position for drilling without impact in wood,
metal, ceramic and plastic as well as for
screwdriving
Vario-Lock position for adjustment of the
chiselling position
The mode selector switch 11 does not latch in
this position.
Position for chiselling
Reversing the rotational direction (see figure L)
The rotational direction switch 8 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 9 actuated.
Right rotation: Push the rotational direction switch 8 left
to the stop.
Left rotation: Push the rotational direction switch 8 right
to the stop.
Set the direction of rotation for hammer drilling, drilling and
chiselling always to right rotation.
Switching On and Off
To save energy, only switch the power tool on when using it.
– To start the machine, press the On/Off switch 9.
Bosch Power Tools
When starting the machine for the first time, a starting delay
is possible, as the electronic system of the power tool has to
configure itself first.
– To switch off the machine, release the On/Off switch 9.
Setting the Speed/Impact Rate
The speed/impact rate of the switched on power tool can be
variably adjusted, depending on how far the On/Off switch 9
is pressed.
Light pressure on the On/Off switch 9 results in low speed/im-
pact 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 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.
Temperature Control Indicator
The red LED of the temperature control indicator 14 signals
that the battery or the electronics of the power tool (when the
battery is inserted) are not within the optimum temperature
range. In this case, the power tool will not operate at full ca-
pacity.
Temperature control of the battery:
– The red LED 14 lights up continuously after inserting the
battery into the charger: The battery is not within the
charging temperature range between 0 °C and 45 °C and
cannot be charged.
– The red LED 14 flashes when pushing button 16 or press-
ing the On/Off switch 9 (when the battery is inserted): The
battery is not wihin the temperature range for operation of
–10 °C to +60 °C.
– For battery temperatures over 70 °C, the power tool
switches off until the battery is in the optimal temperature
range again.
Temperature control of the power tool electronics:
– The red LED 14 lights up continuously when pressing the
On/Off switch 9: The temperature of the machine's elec-
tronics is below 5 °C or above 75 °C.
– At a temperature above 90 °C , the electronics of the pow-
er tool switch off until the temperature is within the allow-
able temperature range again.

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 11 to the "Vario-Lock" posi-
tion (see "Setting the operating mode", page 19).
– Turn the tool holder to the desired chiselling position.
– Turn the mode selector switch 11 to the "chiselling" posi-
tion. The tool holder is now locked.
