Insert the charged battery 8 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 battery is secure-
ly locked.
Reversing the Rotational Direction (see figure G)
The rotational direction switch 5 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 6 actuated.
Right Rotation: For drilling and driving in screws, push the
rotational direction switch 5 left to the stop.
Left Rotation: For loosening and unscrewing screws and
nuts, press the rotational direction switch 5 through to the
right stop.
Setting the Torque
The required torque can be preselected in 15 steps with the
torque preselection ring 2. With the correct setting, the insert
tool is stopped as soon as the screw is screwed flush into the
material or when the set torque is reached.
Select a higher setting when driving out screws, or set to the
symbol "Drilling".
Gear Selection, Mechanical
The gear selector 3 can be actuated at standstill or
when the machine is running. However, this should not
be done while operating at full load or maximum speed.
Two speed ranges can be preselected with the gear selector 3.
Gear I:
Low speed range; for screwdriving or working with large drill-
ing diameter.
Gear II:
High speed range; for working with small drilling diameter.
If the gear selector 3 cannot be pushed through to the stop,
lightly turn the drill chuck with drill.
Setting the Operating Mode
Drilling and Screwdriving
Set the preselection ring 2 to the
"Drilling without impact" symbol.
Impact Drilling (GSB 36 V-LI)
Set the preselection ring 2 to the
"Impact drilling" symbol.
Switching On and Off
To start the machine, press the On/Off switch 6 and keep it
pressed.
To switch off the machine, release the On/Off switch 6.
Adjusting the Speed
The speed of the switched on power tool can be variably ad-
justed, depending on how far the On/Off switch 6 is pressed.
Light pressure on the On/Off switch 6 results in a low rotation-
al speed. Further pressure on the switch results in an increase
in speed.
Fully automatic spindle locking (Auto-lock)
When the On/Off switch 6 is not pressed, the drill spindle and
thus the tool holder are locked.

This enables screws to be screwed in, even when the battery is
empty and allows for the machine to be used as a screwdriver.
Run-on Brake
When the On/Off switch 6 is released, the chuck brakes to a
stop, thus preventing the run-on of the tool.
When driving in screws, wait until the screw is screwed in
flush with the material and then release the On/Off switch 6.
By doing so, the head of the screw does not penetrate into the
material.
Temperature Control Indicator
The red LED of the temperature control indicator 11 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 11 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 11 flashes when pushing button 13 or press-
ing the On/Off switch 6 (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 11 lights up continuously when pressing the
On/Off switch 6: 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
Apply the power tool to the screw/nut only when it is
switched off. Rotating tool inserts can slip off.
Soft Grip
The gripping surface (soft grip) 4 reduces the danger of slip-
ping and thereby improves the grip on the machine and the
handling.
At the same time, the rubber coating achieves a vibration-re-
ducing effect.
Tips
After longer periods of working at low speed, allow the ma-
chine to cool down by running it for approx. 3 minutes at max-
imum speed with no load.
For drilling in metal, use only perfectly sharpened HSS drill
bits (HSS=high-speed steel). The appropriate quality is guar-
anteed by the Bosch accessories program.
Before screwing larger, longer screws into hard materials, it is
advisable to predrill a pilot hole with the core diameter of the
2
thread to approx.
/
of the screw length.
