Servicing your air cleaner
A dirty air cleaner will block air flowing into the carburettor, causing running problems. To keep the carburettor in good working conditions, please service the air cleaner periodically. If you operate the engine in extremely dusty areas, the filter should be replaced more often.
Warning
Never clean the air cleaner in gasoline or low flash-point detergents, an explosion or fire may happen.
CAUTION
Never run the engine without an air cleaner, or air with dirt and dust may enter the engine, fast engine wear and damage.
