Abstract
A motor saw wherein combustion air is drawn via a port tangentially located at the fan wheel in the fan housing of the motor saw. The combustion air is taken from an air stream in circulation from an air inlet at the top surface of the motor saw body where the concentration of pollutants is low. Pollutants are separated by the centrifugal effect of the fan before the air gets into the port. The cooling capacity of the air stream is completed with further cooling air from a second inlet. The combustion air can be pre-heated in a heating loop.
