Note 1:
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.
Note 2:
Reported data for equivalent sound pressure level for the machine has a typical
statistical dispersion (standard deviation) of 1 dB(A).
Note 3:
Reported data for equivalent vibration level has a typical statistical dispersion
(standard deviation) of 1 m/s
