WARNING POTENTIAL HAZARD Using low flash point solvents or gasoline to clean the foam cover. WHAT CAN HAPPEN Low flash point solvents or gasoline can catch fire or explode. HOW TO AVOID THE HAZARD Use parts cleaning solvent to clean the foam cover. 7. Squeeze the excess water or solvent out of the foam cover and let it dry. NOTE: The air filter element should be cleaned every 20 ~ 40 hours. It should be cleaned more often if the machine is operated in extremely dusty areas. Each time filter element maintenance is performed, check the air inlet to the filter case for obstructions. Check the air cleaner rubber joint to the carburetor and manifold fittings for an airtight seal. Tighten all fittings securely to avoid the possibility of unfiltered air entering the engine. CAUTION: ● ● CAUTION: Never operate the engine with the air filter element removed. This will allow unfiltered air to enter, causing rapid engine wear and possible engine damage. Additionally, operation without the filter element will affect carburetor jetting with subsequent poor performance and possible engine overheating. Do not twist the foam cover when squeezing it. Do not add oil to the foam cover. 8. Inspect the foam cover. If damaged, replace it. 9. Reinstall the foam cover to the air filter element. 10. Reinstall the air filter assembly and parts removed for access. 8-14
