Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment ad-
ditives (chromate, wood preservative). 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 ma-

Operation

Starting Operation

Inserting the battery
Note: The use of batteries unsuitable for your power tool can
lead to malfunctions or damage to the power tool.
Set the rotational direction switch (6) to the middle position
to avoid unintentionally switching it on. Insert the charged
battery (10) into the handle until you feel it engage and it is
flush with the handle.
Setting the Rotational Direction (see figure C)
The rotational direction switch (6) is used to change the ro-
tational direction of the power tool. However, this is not pos-
sible while the on/off switch (12) is being pressed.
Right rotation: To drill and to drive in screws, press the ro-
tational direction switch (6) through to the left stop.
Left Rotation: To loosen and unscrew screws and nuts,
press the rotational direction switch (6) through to the right
stop.
Setting the Operating Mode
Drilling
GSR 18-2-LI:
Set the torque presetting ring (3) to the re-
quired torque.
GSB 18-2-LI:
Set the operating mode presetting ring (4) to
the "drilling" symbol.
Screwdriving
GSR 18-2-LI:
Set the torque presetting ring (3) to the re-
quired torque.
GSB 18-2-LI:
Set the operating mode presetting ring (4) to
the "screwdriving" symbol.
Set the torque presetting ring (3) to the re-
quired torque.
Impact drilling (GSB 18-2-LI)
Set the operating mode presetting ring (4) to
the "impact drilling" symbol.
Bosch Power Tools
Preselecting the Torque
The torque presetting ring (3) can be used to preselect the
required torque in 20 stages. When the correct setting is
used, the application tool will be stopped when the screw is
driven flush into the material or once the set torque has been
reached. In position the overload clutch is deactivated,
e.g. for drilling.
When unscrewing screws, you can select a higher setting or
set the tool to the symbol.
Switching on/off
To start the power tool, press and hold the on/off switch
(12).
The LED (11) lights up when the on/off switch (12) is lightly
or fully pressed, meaning that the work area is illuminated in
poor lighting conditions.
To switch off the power tool, release the on/off switch (12).
Adjusting the Speed
You can adjust the speed of the power tool when it is on by
pressing in the on/off switch (12) to varying extents.
A light pressure on the on/off switch (12) results in a low ro-
tational speed. Increased pressure on the switch causes an
increase in speed.
Temperature-dependent overload protection
In normal conditions of use, the power tool cannot be over-
loaded. If the power tool is overloaded or the permitted bat-
tery temperature is exceeded, the electronics of the power
tool will switch off until the temperature returns to within the
optimum operating temperature range.
Protection against deep discharge
The lithium-ion battery is protected against deep discharge
by the "Electronic Cell Protection (ECP)". When the battery
is discharged, the power tool is switched off by means of a
protective circuit: The application tool no longer rotates.
Mechanical gear selection
Only operate the gear selector (5) when the power
u
tool is not in use.
Always push the gear selector switch as far as it will
u
go. Otherwise, the power tool may become damaged.
First gear:
Low speed range; for working with a large drilling diameter
or for screwdriving.
Second gear:
High speed range; for working with a small drilling diameter.

Practical advice

Only apply the power tool to the screw when the tool
u
is switched off. Rotating application tools can slip off.
An auxiliary tool can be used to remove the screwdriver bit
or universal bit holder.
Belt clip
You can use the belt clip (8) to hang the power tool on a belt,
for example. You then have both hands free and the power
tool is always at hand.
