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 mea-
sured with all the approved cutting attachments for the machine. The table indicates the
lowest and highest values.
