8. Maintenance

AIR FILTER

•The air filter, if clogged, will reduce the engine perfor- mance. Check and clean the filter element in warm, soapy water as required. Dry completely before in- stalling. If the element is broken or shrunk, replace with a new one.

FUEL FILTER

•When the engine runs short of fuel supply, check the fuel cap and the fuel filter for blockage.

WAY OF THE COOLING AIR

･This engine is air-cooled. Dust clogging between the inlet port of the cooling air and cylinder fins will cause overheating of the engine. Periodically check and clean the cylinder fins after removing the air cleaner and the cylinder cover.
