|
|
Equivalent sound pressure level at the operator’s ear, measured |
|
|
according to EN 1454 dB(A) | 97 |
|
Vibration levels |
|
|
Handle vibrations measured according to ISO 19432 | 12” (300 mm) | 14” (350 mm) |
Front handle, equivalent value, m/s2 | 3,2 | 3,0 |
Rear handle, equivalent value, m/s2 | 4,6 | 5,0 |
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
working conditions with the following time distribution: 1/2 idling and 1/2 max speed.
