FUEL HANDLING Fuel CAUTION! The machine is equipped with a two-stroke engine and must always been 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. WARNING! Always ensure there is ! adequate ventilation when handling fuel. Gasoline CAUTION! Always use high grade oil mixed gasoline (minimum 87 RON). • This engine is certified to operate on unleaded gasoline. • The lowest recommended octane rating is 87. If you run the engine on lower octane rating than 87 socalled "knocking" can occur. This leads to an increased engine temperature, which can result in a serious engine breakdown. • When working at continuous high revs a higher octane rating is recommended. Use good quality unleaded gasoline. Two-stroke oil • For best results and performance use HUSQVARNA two-stroke oil, which is specially formulated for our two-stroke engines. Mixture 1:50 (2%). • If HUSQVARNA two-stroke oil is not available, you may use another two-stroke oil of good quality that is intended for air cooled engines. Contact your dealer when selecting an oil. • Never use two-stroke oil intended for water-cooled outboard engines, sometimes referred to as outboard oil. • Never use oil intended for four-stroke engines.
