Dust/Chip Extraction; Starting Operation - Bosch GWB 10,8 V-LI Professional Notice Originale

14 | English
The lithium-ion battery can be charged at any time without re-
ducing its service life. Interrupting the charging procedure
does not damage the battery.
 Do not continue to press the On/Off switch after the
machine has been automatically switched off. The bat-
tery can be damaged.
To remove the battery 8 press the unlocking buttons 7 and
pull out the battery downwards. Do not exert any force.
Observe the notes for disposal.
Changing the Tool (see figure B)
 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.
The drill spindle is locked when the On/Off switch 4 is not
pressed. This makes quick, convenient and easy changing of
the tool in the drill chuck possible.
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 .

Dust/Chip Extraction

 Dusts from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one's health. Touching or breathing-in the dusts can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dusts, such as oak or beech dust, are considered
as carcinogenic, especially in connection with wood-treat-
ment additives (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
materials to be worked.
 Prevent dust accumulation at the workplace. Dusts can
easily ignite.
Operation

Starting Operation

Inserting the battery
 Use only original Bosch lithium ion batteries with the
voltage listed on the nameplate of your power tool. Us-
ing other batteries can lead to injuries and pose a fire haz-
ard.
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 3 to the centre position in
order to avoid unintentional starting. Insert the charged bat-
tery 8 into the handle so that it can be felt to engage and faces
flush against the handle.

Reversing the rotational direction (see figure C)
The rotational direction switch 3 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 4 actuated.
Right Rotation: For drilling and driving in screws, push the
rotational direction switch 3 left to the stop.
Left Rotation: For loosening or unscrewing screws, push the
rotational direction switch 3 right to the stop.
Switching On and Off
To start the machine, press the On/Off switch 4 and keep it
pressed.
The power light 1 lights up when the On/Off switch 4 is slightly
or completely pressed, and allows the work area to be illumi-
nated when lighting conditions are insufficient.
To save energy, only switch the power tool on when using it.
To switch off the machine, release the On/Off switch 4.
Adjusting the Speed
The speed of the switched on power tool can be variably ad-
justed, depending on how far the On/Off switch 4 is pressed.
Light pressure on the On/Off switch 4 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 4 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 4 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 4.
By doing so, the head of the screw does not penetrate into the
material.
Battery Charge-control Indication
The battery charge-control indicator 6 consists of three green
LEDs, and indicates the charge condition of the battery for a
few seconds when the On/Off switch 4 is pressed halfway or
fully.
LED
Continuous lighting 3 x green
Continuous lighting 2 x green
Continuous lighting 1 x green
Flashing light 1 x green
Temperature Dependent Overload Protection
When using as intended for, the power tool cannot be subject
to overload. When the load is too high or the allowable battery
temperature of 70 °C is exceeded, the electronic control
switches off the power tool until the temperature is in the op-
timum temperature range again.
