Sound levels

(see note 1)

Equivalent sound pressure level at the user′s ear, measured 99/104 according to ANSI B175.3-1997, dB(A), min/max:

Vibration levels
Vibration levels at handles, measured according to
ANSI B175.3-1997, m/s2
At idle, left/right handles, min.:	3,7/4,5
At idle, left/right handles, max.:	4,0/4,7
At max. speed, left/right handles, min.:	2,1/2,3
At max. speed, left/right handles, max.:	2,5/2,7

99/10499/104

3,0/3,94,0/4,7

0,8/1,22,1/2,3

1,2/1,92,5/2,7

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.
