The vibration level given in these instructions has been
measured in accordance with a standardised measuring pro-
cedure and may be used to compare power tools. It can also
be used for a preliminary estimation of exposure to vibra-
tion.
The stated vibration level applies to the main applications of
the power tool. However, if the power tool is used for differ-
ent applications, with different application tools or poorly
maintained, the vibration level may differ. This can signific-
antly increase the exposure to vibration over the total work-
ing period.
To estimate the exposure to vibration accurately, the times
when the tool is switched off or when it is running but not ac-
tually being used should also be taken into account. This can
significantly reduce the exposure to vibration over the total
working period.
Implement additional safety measures to protect the oper-
ator from the effects of vibration, such as servicing the
power tool and application tools, keeping the hands warm,
and organising workflows correctly.
Assembly
Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
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-
