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.
