[. . . ] If you have spilt fuel on yourself or your clothes, change your clothes. If your machine is equipped with a catalytic converter (see chapter on Technical data) always use a good quality unleaded petrol/oil mixture. Use low-emission petrol, also known as alkylate petrol, if it is available. Store and transport the machine and fuel so that there is no risk of any leakage or fumes coming into contact with sparks or naked flames, for example, from electrical machinery, electric motors, electrical relays/ switches or boilers. When storing and transporting fuel always use approved containers intended for this purpose. When storing the machine for long periods the fuel tank must be emptied. Contact your local petrol station to find out where to dispose of excess fuel. Ensure the machine is cleaned and that a complete service is carried out before long-term storage. The transport guard must always be fitted to the cutting attachment when the machine is being transported or in storage. In order to prevent unintentional starting of the engine, the spark plug cap must always be removed during long-term storage, if the machine is not under close supervision and when performing all service measures. If you run the engine on a lower octane grade than 90 socalled 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. For best results and performance use HUSQVARNA two-stroke engine oil, which is specially formulated for our air-cooled two-stroke engines. Never use two-stroke oil intended for water-cooled engines, sometimes referred to as outboard oil (rated TCW). A poor oil quality and/or too high oil/fuel ratio may jeopardise function and decrease the life time of catalytic converters. 1:33 (3%) with oils class JASO FB or ISO EGB formulated for air-cooled, two-stroke engines. 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. 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. [. . . ] However, before using the machine you should check that the bevel gear is filled three-quarters full with grease. The grease in the bevel gear does not normally need to be changed except if repairs are carried out. Clean the filter every 25 hours, or more regularly if conditions are exceptionally dusty. An air filter that has been in use for a long time cannot be cleaned completely. [. . . ]
