– Without switching the power tool on, apply it firmly to the
drilling location. The SDS-plus drilling tool must face
against the surface.
– Position the the guide pipe 26 of the dust extraction at-
tachment in its holding fixture in such a manner that the
head of the dust extraction attachment faces against the
surface to be drilled. Do not slide the guide pipe 26 further
over the telescopic pipe 24 of the dust extraction attach-
ment than required, so that as much as possible of the
scale 24 on the telescopic pipe remains visible.
– Retighten the wing bolt 25 again. Loosen the clamping
screw 22 on the depth stop of the dust extraction attach-
ment.
– Move the depth stop 23 on the telescopic pipe 24 in such
a manner that the clearance X shown in the figure corre-
sponds with the required drilling depth.
– Tighten the clamping screw 22 in this position.
Operation
Starting Operation
Inserting the battery
Use only original Bosch lithium-ion batteries with the
voltage listed on the nameplate of your power tool.
Using other batteries can lead to injuries and pose a fire
hazard.
– Set the rotational direction switch 7 to the centre position
to protect the power tool against accidental starting.
– Insert the charged battery 12 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
With the selector switch for drilling/hammer drilling 9, the op-
erating mode of the machine is selected.
Note: Change the operating mode only when the machine is
switched off! Otherwise, the machine can be damaged.
– To change the operating mode, turn the selector switch for
"drilling/hammer drilling" 9 to the requested position.
Position for hammer drilling in concrete or
stone
Position for drilling without impact in wood,
metal, ceramic and plastic as well as for
screwdriving
Reversing the rotational direction (see figure J)
Right rotation: Push the rotational direction switch 7 left
to the stop.
Left rotation: Push the rotational direction switch 7 right
to the stop.
For hammer drilling and drilling, always set the direction of ro-
tation to right rotation.

Switching On and Off
– To start the machine, press the On/Off switch 8.
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 save energy, only switch the power tool on when using it.
– To switch off the machine, release the On/Off switch 8.
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 8
is pressed.
Light pressure on the On/Off switch 8 results in low speed/im-
pact rate. Further pressure on the switch increases the
speed/impact rate.
Overload 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 you press the 16 button or
the On/Off switch 8 (with battery inserted): The battery is
outside of the permitted operating temperature range.
– 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 8: 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
Vibration Damper
The integrated vibration damper reduces occurring vibra-
tions.
