The specifications apply to a rated voltage [U] of 230 V. For different voltages and models for specific countries, these values can vary.
Geräusch-/Vibrationsinformation
Noise emission values determined according to
EN 62841-2-4
.
Typically, the A-weighted sound pressure level of the power
tool is
77
dB(A). Uncertainty K = 2.8 dB. The noise level
when working can exceed 80 dB(A).

The vibration level and noise emission value given in these
instructions have been measured in accordance with a
standardised measuring procedure detailed in EN 62841
and may be used to compare power tools. They may also be
used for a preliminary estimation of vibration and noise
emissions.
The given 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 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 the hands warm,
and organising workflows correctly.
Assembly
u
Pull the plug out of the socket before carrying out any
work on the power tool.
