摘要：A manually guided implement having an air-cooled internal combustion engine for driving a tool is provided. The engine is disposed in a housing, with cooling air being conveyed by a fan wheel that is fixedly held on the crankshaft of the engine and that is accommodated in a cooling air spiral case that is open toward the engine. Formed in the housing is an air inlet via which ambient air can be drawn into the cooling air spiral case. A base of the spiral case is disposed between the fan wheel and the engine and is provided with a second cooling air inlet that provides communication between the interior of the housing and portions of the cooling air spiral case that convey cooling air.
