Technical data
• The data shown above are those in the case of one straight pipe and round pipe.
• Specifications are subject to change without notice.
Note 1: Noise emissions in the environment measured as sound power (L
WA
) in conformity with EC directive 2000/14/EC. Reported sound
power level for the machine has been measured with the original attachment that gives the highest level. The difference between
guaranteed and measured sound power is that the guaranteed sound power also includes dispersion in the measurement result and the
variations between different machines of the same model according to Directive 2000/14/EC.
Note 2: 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 3: The equivalent vibration total 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
2 .
