Noise emissions in the environment measured as sound power (L
WA
) in conformity with EC directive 2000/14/
EC. Reported sound power level for the machine has been measured with the original cutting attachment
that gives the highest level. The difference between guaranteed and measured sound power is that the
guaranteed sound power also includes dispersion in the measurement result and the variations between
different machines of the same model according to Directive 2000/14/EC.
4
Reported data for equivalent sound pressure level for the machine has a typical statistical dispersion (stand-
ard deviation) of 1 dB(A).
5
Reported data for equivalent vibration level has a typical statistical dispersion (standard deviation) of 1 m/s
