Changing the Tool (see figure A)
 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.
Open the keyless chuck 2 by turning in rotation direction ,
until the tool can be inserted. Insert the tool.
Firmly tighten the collar of the keyless chuck 2 by hand in ro-
tation direction . This automatically locks the drill chuck.

Dust/Chip Extraction

 Dust from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one's health and cause allergic reactions, lead to res-
piratory infections and/or cancer. Materials containing
asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the
materials to be worked.
 Prevent dust accumulation at the workplace. Dust can
easily ignite.
Operation

Starting Operation

Inserting the battery
Note: Use of batteries not suitable for the machine can lead to
malfunctions of or cause damage to the power tool.
Set the rotational direction switch 10 to the centre position in
order to avoid unintentional starting. Insert the charged bat-
tery 7 into the handle so that it can be felt to engage and faces
flush against the handle.
Reversing the rotational direction (see figure B)
The rotational direction switch 10 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 11 actuated.
Right Rotation: For drilling and driving in screws, push the
rotational direction switch 10 left to the stop.
Left Rotation: For loosening or unscrewing screws, push the
rotational direction switch 10 right to the stop.
Setting the operating mode
Drilling
GSR 140-LI, GSR 180-LI:
Set the torque selector setting ring 3 to the re-
quired torque.
GSB 140-LI, GSB 180-LI:
Set the operating mode selector switch 4 to the
"drilling" symbol.
Bosch Power Tools
Screwdriving
GSR 140-LI, GSR 180-LI:
Set the torque selector setting ring 3 to the
"screwdriving" symbol.
GSB 140-LI, GSB 180-LI:
Set the operating mode selector switch 4 to the
"screwdriving" symbol.
Impact drilling
GSB 140-LI, GSB 180-LI:
Set the operating mode selector switch 4 to the
"impact drilling" symbol.
Switching On and Off
To start the machine, press the On/Off switch 11 and keep it
pressed.
The LED 9 lights up when the On/Off switch 11 is halfway or
fully pressed, and enables illumination of the screwing loca-
tion in unfavourable light conditions.
To save energy, only switch the power tool on when using it.
Adjusting the Speed
The speed of the switched-on power tool can be variably ad-
justed, depending on how far the On/Off switch 11 is
pressed.
Light pressure on the On/Off switch 11 results in a low rota-
tional speed. Further pressure on the switch results in an in-
crease in speed.
Setting the torque
With the torque preselection ring 3, the required torque can
be preselected in 20 steps. The inserted tool is stopped as
soon as the set torque is reached.
Gear selection, mechanical
 The gear selector 5 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.
1st gear:
Low speed range; for working with large drilling diameters.
2nd gear:
High speed range; for drilling with small drilling diameter.
Temperature Dependent Overload Protection
In normal conditions of use, the power tool cannot be over-
loaded. If the power tool is overloaded or the battery temper-
ature is not kept within the permitted range, the power tool
switches off and the LED on the power tool flashes. Allow the
power tool to cool down before you carry on working.
Protection Against Deep Discharging
The lithium-ion battery is protected against deep discharging
by the "Electronic Cell Protection (ECP)". When the battery is
empty, the machine is switched off by means of a protective
circuit: The inserted tool no longer rotates.
Rapid Shut-off
The rapid shut-off feature enables better control of the power
tool. The power tool shuts off in case of sudden and unexpect-
ed rotation of the power tool around the drilling axis.
