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 product has been measured with the original cutting attach-
ment 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 dif-
ferent prodducts of the same model according to Directive 2000/14/EC.
2
Reported data for noise pressure level has a typical statistical dispersion (standard deviation) of 1 dB (A).
3
Reported data for vibration level has a typical statistical dispersion (standard deviation) of 1 m/s
