FUEL HANDLING General WARNING! Running an engine in a confined ! or badly ventilated area can result in death due to asphyxiation or carbon monoxide poisoning. Use fans to ensure proper air circulation when working in trenches or ditches deeper than one meter. Fuel and fuel fumes are highly inflammable and can cause serious injury when inhaled or allowed to come in contact with the skin. For this reason observe caution when handling fuel and make sure there is adequate ventilation. The exhaust fumes from the engine are hot and may contain sparks which can start a fire. Never start the machine indoors or near combustible material! Do not smoke and do not place any hot objects in the vicinity of fuel. Fuel NOTICE! The machine is equipped with a two-stroke engine and must always been run using a mixture of petrol and two-stroke 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. Petrol • Use good quality unleaded or leaded petrol. • The lowest octane recommended is 90 (RON). If you run the engine on a lower octane grade than 90 so-called knocking can occur. This gives rise to a high engine temperature, which can result in serious engine damage. • When working at continuous high revs a higher octane rating is recommended. Environment fuel HUSQVARNA recommends the use of alkylate fuel, either Aspen two-stroke fuel or environment fuel for four-stroke engines blended with two-stroke oil as set out below. Note that carburettor adjustment may be necessary when changing the type of fuel (see the instructions under the heading Carburettor). Two-stroke oil K760 • For best results and performance use HUSQVARNA twostroke engine oil, which is specially formulated for our aircooled two-stroke engines. • Never use two-stroke oil intended for water-cooled engines, sometimes referred to as outboard oil (rated TCW). • Never use oil intended for four-stroke engines. K760 OilGuard • Use HUSQVARNA OilGuard two stroke oil. Mixing • Always mix the petrol and oil in a clean container intended for fuel. • Always start by filling half the amount of the petrol to be used. Then add the entire amount of oil. Mix (shake) the fuel mixture. Add the remaining amount of petrol. • Mix (shake) the fuel mixture thoroughly before filling the machine's fuel tank. • Do not mix more than one month's supply of fuel at a time. Mixing ratio (K760) • 1:50 (2%) with HUSQVARNA two-stroke oil or equivalent. • 1:33 (3%) with oils class JASO FB or ISO EGB formulated for air-cooled, two-stroke engines.
