At idle, left/right handles: 3/5 3/5
At max. speed, left/right handles: 9/8 9/8
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.
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.
