Abstract
The invention relates to a cutting machine, circular saw machine or the like powered by an internal combustion engine. The machine comprises a cutting unit or corresponding unit having a rotational tool, and a power unit, which comprises an air-cooled motor cylinder in a motor room limited by a casing which at least partly consists of a cylinder cover; and an impeller rotatable about the crank shaft with impeller wings, which during rotation propels a cooling air flow outwards toward the periphery of a fan housing and further to the motor room under and inside the cylinder cover. At least a first filter chamber with a filter for intake air for the internal combustion engine is provided over the cylinder cover, and a nozzle tube for the intake air extends from an intake port close to the periphery of the impeller up through the motor room terminating in the at least first filter chamber over the cylinder cover.
