Abstract
A drive system for a tool, particularly a chain saw, includes a fresh air inlet and an intake manifold arranged after the fresh air inlet in the flow direction of the fresh air that opens into a carburettor. A combustion engine is provided that is arranged after the carburettor in the flow direction of an air-fuel mixture produced in the carburettor, in which the carburettor is exposed to a lower level of thermal stress. At least one heat conducting cooling vane is connected to the carburettor and protrudes outwards into direct contact with the ambient fresh air.
