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 screwdriv-
er.
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 you press the 13 button or
the On/Off switch 6 (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 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.

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.
If the machine should fail despite the care taken in manufac-
turing 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 in-
clude the 10-digit article number given on the type plate of
the machine.
Replacing the Carbon Brushes (see figure H)
When the carbon brushes are worn, the power tool switches
off automatically. For replacement of the carbon brushes, un-
screw the screws of the cover lids 19 and remove the cover
lids 19. Insert a screwdriver or similar into the notch of the
brush holder 20 and and carefully pry it out. Remove the used
carbon brushes and replace them. The new carbon brushes
can also be inserted when turned by 180°. Lightly press the
inserted carbon brushes downward until they can be clearly
heard to engage. Afterwards mount the cover lids 19 again.
