The specifications apply to a rated voltage [U] of 230 V. These spe-
cifications may vary at different voltages and in country-specific mod-
els.
Values can vary depending on the product, scope of application and

Noise/Vibration Information
Noise emission values determined according
to EN 62841‑2‑4.
Typically, the A-weighted noise level of the power tool is:
Sound pressure level 91 dB(A); sound power
level 99 dB(A). Uncertainty K = 3 dB.
Wear hearing protection!
Vibration total values a (triax vector sum) and uncertainty K

a = 2.5 m/s , K = 1.5 m/s .

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-
1 609 92A 96H | (16.01.2024)
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 ac-
cessories or is poorly maintained, the vibration level and
noise emission value may differ. This may significantly in-
crease the vibration and noise emissions over the total work-
ing 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 accessories, keeping their hands warm, and
organising workflows correctly.

– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.

Self-generated dust extraction with dust bag
A dust bag (accessory) (10) can be used for smaller jobs.
Firmly attach the dust bag nozzle to the extraction outlet (9).
Empty the dust bag (10) at regular intervals to maintain op-
timum dust collection.
External dust extraction
Fit a dust extraction hose onto the extraction outlet (9).
Connect the dust extraction hose to an extractor. You will
find an overview of connecting to various dust extractors at
the end of these operating instructions.
The dust extractor must be suitable for the material being
worked.
When extracting dry dust that is especially detrimental to
health or carcinogenic, use a special dust extractor.
Pull the plug out of the socket before carrying out any
work on the power tool.
terial wherever possible.
Avoid dust accumulation at the workplace. Dust can
easily ignite.
