|
When idling, left/right handles, min: | 1,6/2,2 | 2,5/2,5 | 2,2/2,7 |
When idling, left/right handles, max: | 1,8/3,0 | 3,0/3,5 | 2,7/4,3 |
At max. speed, left/right handles, min: | 2,0/2,7 | 2,0/2,0 | 3,5/5,0 |
At max. speed, left/right handles, max: | 3,1/6,0 | 5,1/4,9 | 4,5/6,2 |
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
working conditions with the following time distribution: 1/2 idling and 1/2 max speed.
NOTE! Noise and vibration measurements are made with all the machine’s approved cutting equipment fitted. The table indicates the highest and lowest values.
