TECHNICAL DATA
Technical data
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
de
viation) of 1 dB (A).
Note 3: Reported data for equivalent vibration level has a typical statistical dispersion (standard deviation) of 1 m/s
