Note 1: Equivalent noise pressure level is calculated as the time-weighted energy total for noise pressure levels under various
working conditions with the following time distribution: 1/2 idle and 1/2 max. speed.
working conditions with the following time distribution: 1/2 idle 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.
