Abstract

The air inlet of the cooling fan is positioned substantially on top of a motor saw body so that the air is drawn from a region above the saw where the concentration of pollutants is considerably lower than at the usually known inlet through the fan cover. The air inlet is positioned at a distance from the fan cover to provide a connecting channel between the inlet and the fan wheel, in which channel a shunt damper is arranged. The shunt channel enables a balanced mixture of cold outdoor air and warm recirculating inner air so that a proper engine temperature can be effected.
