Typically, the A-weighted sound pressure level of
the power tool is 71 dB(A). Uncertainty K=5 dB.
The noise level when working can exceed the
volume stated. Wear hearing protection!

The vibration level and noise emission value given
in these instructions have been measured in ac-
cordance with a standardised measuring proced-
ure and may be used to compare power tools.
They may also be used for a preliminary estima-
tion of vibration and noise emissions.
The stated vibration level and noise emission
value represent the main applications of the
power tool. However, if the power tool is used for
other applications, with different application tools
or is poorly maintained, the vibration level and
noise emission value may differ. This may signific-
antly increase the vibration and noise emissions
over the total working period.
To estimate vibration and noise emissions accur-
ately, 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 signi-
ficantly reduce vibration and noise emissions over
the total working period.
Implement additional safety measures to protect
the operator from the effects of vibration, such as
servicing the power tool and application tools,
keeping their hands warm, and organising work-
flows correctly.
Assembly
English
Remove the battery from the power tool be-
u
fore carrying out work on the power tool (e.g.
maintenance, changing tool, etc.). The bat-
tery should also be removed for transport and
storage. There is risk of injury from unintention-
ally pressing the on/off switch.
Charging the Battery (see figure A)
Use only the chargers listed in the technical
u
data. Only 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 bat-
tery 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)". When the battery is discharged, the power

tool is switched off by means of a protective cir-
cuit: The application tool no longer rotates.
u
To remove the battery (5), press the release but-
tons (4) 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)
u
The drill spindle is locked when the on/off switch
(7) is not pressed. This makes it possible to
change the application tool in the drill chuck
quickly, conveniently and easily.
Open the keyless chuck (1) by turning it in the dir-
ection of rotation ➊ until the tool can be inserted.
Insert the tool.
Firmly tighten the sleeve of the keyless chuck (1)
by turning it by hand in the direction of rotation ➋
until it audibly clicks into place. This will automat-
ically lock the drill chuck.
Dust/Chip Extraction
Dust from materials such as lead-containing coat-
ings, 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 con-
sidered carcinogenic, especially in connection
with wood-treatment additives (chromate, wood
preservative). Materials containing asbestos may
only be worked by specialists.

– It is recommended to wear a P2 filter-class res-
Observe the relevant regulations in your country
for the materials to be worked.
u
Do not continue to press the On/Off switch
after the power tool has automatically
switched off. The battery can be damaged.
Remove the battery from the power tool be-
fore carrying out work on the power tool (e.g.
maintenance, changing tool, etc.). The bat-
tery should also be removed for transport and
storage. There is risk of injury from unintention-
ally pressing the on/off switch.
