Note 1: Noise emissions in the environment measured as sound power (LWA) 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, 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.
