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