Abstract
A power cutter with an engine and with a cutting arm on which a cutting tool is received and is driven by the engine by way of a belt is provided. The belt may be received in a belt space formed in the cutting arm, and a fan wheel is arranged on the engine so that an air flow for cooling the engine can be generated. A combustion-air flow is provided to the engine, and the fan wheel provides an air circulation system where an air flow at least flows through the belt space and the combustion-air flow branches off from the air circulation system.
