Sound levels
(see note 1)
Equivalent sound pressure level at the user's ear, 91/98
measured according to ANSI B175.3-1997, dB(A), rain/
max:
Vibration levels
Vibration levels at handles, measured according to ANSI
B175.3-1997, m/s2
At idle, left/right handles, rain.: 2,7/1,5
At idle, left/right handles, max.: 3,5/1,7
At max. speed, left/right handles, min.: 5,1/9,3
At max. speed, left/right handles, max.: 7,8/10,9

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.
