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.
Note 2: Equivalent sound pressure level, according to ISO 7182, 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, 1/3 max. speed.
Note 3: Equivalent vibration level, according to ISO 7505, 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.
