Technical data
Note 1: 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! Noise pressure at the user’s ear and vibration on the handles are measured with all the machine’s approved
cutting equipment fitted. The table indicates the highest and lowest values.
