TECHNICAL DATA
1155849-49 Rev. 2 2013-03-22
Note 1: The equivalent sound pressure level value is calculated with a work cycle of a duration of 1/7 for idling and 6/7
for racing. Reported data for equivalent sound pressure level for the machine has a typical statistical dispersion
(standard deviation) of 1 dB(A).
Note 2: The equivalent vibration level value is calculated with a work cycle of a duration of 1/7 for idling and 6/7 for racing.
Reported data for equivalent vibration level has a typical statistical dispersion (standard deviation) of 1 m/s
