Sound levels

Equivalent sound pressure level at the users ear, measured according to ANSI B175.3-1997, dB(A), min/max:

18,5/8,4

100/103

20,1/9,1

98/104

Vibration levels

 

 

Vibration levels at handles, measured according to ANSI

 

 

B175.3-1997, m/s2

 

 

At idle, left/right handles, min.:

2,5/2,7

3,4/4,0

At idle, left/right handles, max.:

3,5/3,5

3,4/4,0

At max. speed, left/right handles, min.:

3,3/3,3

1,4/3,0

At max. speed, left/right handles, max.:

4,8/5,4

5,8/7,4

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.
