ABSTRACT:
An engine filter assembly for cleaning cooling air for an internal-combustion engine for use in high-debris environment such as in roofing-removing machines includes a filter housing attached to the machine at a remote position. The filter housing houses a two-stage air filter that consists of a cylindrical-shaped filter element with an outer pre-filter covering. Both the carburetor air inlet and a fan housing leading to the cooling fan on the engine are connected to the filter housing by tubing. A shield protects the engine from direct contact with loose or air-borne materials during the operation of the machine. A thermal sensing device reads the temperature of the engine and automatically shuts down the engine if the temperature rises beyond specification, reducing the chance of engine failure.
