measured according to EN ISO 22868, dB(A), min./max.:

 

Vibration levels

 

Vibration levels at handles, measured according to

 

EN ISO 22867, m/s2

 

At idle, left/right handles, min.:

3,8/4,2

At idle, left/right handles, max.:

4,2/4,8

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

6,8/7,9

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

6,9/8,0

Note 1: Noise emissions in the environment measured as sound power (LWA) in conformity with EC directive 2000/14/ EC.

Note 2: 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! The noise pressure level at operator’s ear and vibrations on the handles are measured with all the approved cutting attachments for the machine. The table indicates the lowest and highest values.
