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 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.
