Your engine requires a mixture of highquality gasoline and two-stroke air cooled engine oil. Use mid-grade unleaded gasoline with a minimum octane rating of 89 ((R+M)/2) and no more than 10% ethanol content. NOTICE Fuel with an octane rating below 89 may increase engine temperatures. This, in turn, increases the risk of piston seizure and damage to the engine. The chemical composition of the fuel is also important. Some fuel additives not only detrimentally affect elastomers (carburetor diaphragms, oil seals, fuel lines, etc.), but magnesium castings and catalytic converters as well. This could cause running problems or damage the engine. For this reason STIHL recommends that you use only quality unleaded gasoline! NOTICE Gasoline with an ethanol content of more than 10% can cause running problems and major damage in engines and should not be used. For further details, see www.STIHLusa.com/ethanol The ethanol content in gasoline affects engine speed - it may be necessary to readjust the carburetor if you use fuels with various ethanol contents.
