Noise/vibration information
Noise emission values determined according to
EN 62841-2-1.
Typically, the A-weighted noise level of the power tool is:
Sound pressure level 82 dB(A); sound power level
93 dB(A). Uncertainty K = 3 dB.

The vibration level and noise emission value given in these
instructions have been measured in accordance with a
standardised measuring procedure and may be used to com-
pare power tools. They may also be used for a preliminary
estimation of vibration and noise emissions.
The stated vibration level and noise emission value repres-
ent the main applications of the power tool. However, if the
power tool is used for other applications, with different ap-
plication tools or is poorly maintained, the vibration level
and noise emission value may differ. This may significantly
increase the vibration and noise emissions over the total
working period.
To estimate vibration and noise emissions accurately, the
times when the tool is switched off or when it is running but
not actually being used should also be taken into account.
This may significantly reduce vibration and noise emissions
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 their 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.

Charging the battery
GSB 12V-15
°C
–20 to +50
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
GBA 12V...
full battery capacity, fully charge the battery in the charger
before using your power tool for the first time.
GAL 12...
The lithium-ion battery can be charged at any time without
GAX 18...
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)". When the battery
is discharged, the power tool is switched off by means of a
protective circuit: The application tool no longer rotates.
Do not continue to press the On/Off switch after the
u
power tool has automatically switched off. The battery
can be damaged.
Removing the battery (see figure A)
To remove the battery (8), press the release button (7) and
pull the battery downwards out of the power tool. Do not
use force to do this.
You can also leave the battery (8) inserted in the power tool

switched on. Press the on/off switch (10) to retrieve the bat-
tery charge status. For more information, see the "Battery
charge indicator" section.
Follow the instructions on correct disposal.
Changing the Tool (see figure B)
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.
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. This will automatically lock 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. 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.
