do not use oils labeled “ENERGY CONSERV-
ING II” or higher.●Make sure that no foreign material enters the
crankcase.13. Start the engine, and then let it idle for severalminutes while checking it for oil leakage. If oil
is leaking, immediately turn the engine off and

necessary.EBU23744Cleaning the air filter element The air filter element should be cleaned at the in-
