Temperature Control Indicator
The red LED of the temperature control indicator 19 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 19 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 19 flashes when you press the 21 button or
the On/Off switch 10 (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 19 lights up continuously when pressing the
On/Off switch 10: 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

Adjusting the Drilling Depth (see figure M)
The required drilling depth X can be set with the depth stop
17.
– Press the button for the depth stop adjustment 15 and in-
sert the depth stop into the auxiliary handle 16.
The knurled surface of the depth stop 17 must face down-
ward.
– Insert the SDS-plus drilling tool to the stop into the SDS-
plus tool holder 3. Otherwise, the movability of the SDS-
plus drilling tool can lead to incorrect adjustment of the
drilling depth.
– Pull out the depth stop until the distance between the tip of
the drill bit and the tip of the depth stop corresponds with
the desired drilling depth X.
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 13 to the "Vario-Lock" posi-
tion (see "Setting the operating mode", page 20).
– Turn the tool holder to the desired chiselling position.
– Turn the mode selector switch 13 to the "chiselling" posi-
tion. The tool holder is now locked.
– For chiselling, set the rotation direction to right rotation.
Inserting Screwdriver Bits (see figure N)
 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 31 with
SDS-plus shank (accessory) is required.
Bosch Power Tools
– 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 automatically locks.
– Check the locking effect by pulling the universal 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
5 toward the rear and remove the universal bit holder 31
out of the tool holder.
Vibration Damper
The integrated vibration damper reduces occurring vibra-
tions.
The soft grip handle increases the safety against slipping off
and thus provides for a better grip and handling of the power
tool.
Recommendations for Optimal Handling of the Battery
Protect the battery against moisture and water.
Store the battery only within a temperature range between
–20 °C and 50 °C. As an example, do not leave the battery in
the car in summer.
Occasionally clean the venting slots of the battery using a soft,
clean and dry brush.
A significantly reduced working period after charging indi-
cates that the battery is used and must be replaced.
Observe the notes for disposal.

Maintenance and Service

Maintenance and Cleaning

 Before any work on the machine itself (e. g. mainte-
nance, tool change, etc.) as well as during transport
and storage, remove the battery from the power tool.
There is danger of injury when unintentionally actuating
the On/Off switch.
 For safe and proper working, always keep the machine
and ventilation slots clean.
 A damaged dust protection cap should be changed im-
mediately. We recommend having this carried out by
an after-sales service.
– Clean the tool holder 3 each time after using.
