Dust/Chip Extraction; Starting Operation - Bosch GSR Professional 12V-30 Notice Originale

Removing the battery (see figure A)
Use only the chargers listed in the technical data. Only
u
these chargers are matched to the lithium-ion battery of
your power tool.
Note: The battery is supplied partially charged. To ensure
full battery capacity, fully charge the battery in the charger
before using your power tool for the first time.
The lithium-ion battery can be charged at any time without
reducing its service life. Interrupting the charging process
does not damage the battery.
The lithium-ion battery is protected against deep discharge
by the "Electronic Cell Protection (ECP)". A protective circuit
switches the cordless dust extractor off when the battery is
drained.
Do not continue to press the On/Off switch after the
u
power tool has automatically switched off. The battery
can be damaged.
To remove the battery (8), press the release buttons (7) and
pull the battery downwards out of the power tool. Do not
use force to do this.
Follow the instructions on correct disposal.
Changing the tool (see figure B)
The drill spindle is locked when the on/off switch (10) is not
pressed. This makes it possible to change the application
tool in the drill chuck quickly, conveniently and easily.
Open the keyless chuck (2) by turning it in the direction of
rotation ➊ until the tool can be inserted. Insert the tool.
Firmly tighten the keyless chuck (2) by turning it by hand in
the direction of rotation ➋. You will hear an audible click
from the GSB. The drill chuck is locked automatically.
The lock will disengage again if you turn the sleeve in the op-
posite direction to remove the tool.

Dust/Chip Extraction

Dust 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 dust can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
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-
terials to be worked.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.

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 (8) 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 (10) is being pressed.
Right rotation: To drill and to drive in screws, press the ro-
tational direction switch (6) through to the left stop.
