Technical data
Note 1: Noise emissions in the environment measured as sound power (L
WA
) in conformity with EC directive 2000/14/EC.
Note 2: Equivalent sound pressure level, according to ISO 22868, is calculated as the time-weighted energy total for
noise pressure levels under various working conditions with the following time distribution: 1/3 idling, 1/3 max. load,
noise pressure levels under various working conditions with the following time distribution: 1/3 idling, 1/3 max. load,
1/3 max. speed.
Note 3: Equivalent vibration level, according to ISO 22867, is calculated as the time-weighted energy total for vibration
levels under various working conditions with the following time distribution: 1/3 idling, 1/3 max. load, 1/3 max. speed.
