26 – English

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 is calculated as the time-weighted energy total for sound pressure levels under 
various working conditions with the following time distribution: 1/2 idling and 1/2 max speed.

NOTE!   The noise pressure level at operator’s ear and vibrations on the handles are measured with all the approved 
cutting attachments for the machine. The table indicates the lowest  and highest values.
