9.5 REFUELLING
Use unleaded gasoline with a pump octane rating of 86 or higher. This engine is certified to operate on
unleaded gasoline. Unleaded gasoline produces fewer engine and spark plug deposits and extends exhaust
system life.
WARNING: Gasoline is highly flammable and explosive, and you can be burned or seriously injured when
refueling.
Stop engine and keep heat, sparks, and flame away.
