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.
