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
w
orking 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 f
or the machine. The table indicates the lowest and highest values.
