FUEL HANDLING Fuel mixture CAUTION! The machine is equipped with a two--stroke engine and must always be run using a mixture of gasoline and two-stroke engine oil. It is important to accurately measure the amount of oil to be mixed to ensure that the correct mixture is obtained. When mixing small amounts of fuel, even small inaccuracies can drastically affect the ratio of the mixture. S Always start by flling half the amount of the gasoline to be used. Then add the entire amount of oil. Mix (shake) the fuel mixture. Add the remaining amount of gasoline. S Mix (shake) the fuel mixture thoroughly before filling the machine's fuel tank. WARNING: Always ensure there is adequate ventilation when handling fuel. Gasoline CAUTION! Always use high quality unleaded gasoline. S This engine is certified to operate on unleaded gasoline. S The lowest recommended octane rating is 87. If you run the engine on lower octane rating than 87, "knocking" can oc- cur. This leads to an increased engine temperature, which can result in a serious engine breakdown. S When working at continuous high revs a higher octane rating is recommended. Two--stroke oil S For great results and performance use HUSQVARNA two--stroke oil, which is specially formulated for our two--stroke engines. Mixture 1:50 (2%).
