THE USE OF THE POWER TOOL Transporting the Power Tool Always switch off the engine before taking the machine off your back and putting it down. Empty container when transporting it in a vehicle; properly secure it to prevent turnover, fuel spillage and damage to the unit. Fuel Your STIHL power tool uses an oilgasoline mixture for fuel (see the chapter on "Fuel" in this instruction manual). Warning! Gasoline is an extremely flammable fuel. If spilled and ignited by a spark or other ignition source, it can cause fire and serious burn injury or property damage. Use extreme caution when handling gasoline or fuel mix. Do not smoke or bring any fire or flame near the fuel or the power tool. Note that combustible fuel vapor may escape from the fuel system. Fueling Instructions English Warning! To reduce the risk of serious injury from burns, never attempt to refuel the unit until it has been completely removed from the operator. Warning! Fuel your power tool in well-ventilated areas, outdoors. Always shut off the engine and allow it to cool before refueling. Gasoline vapor pressure may build up inside the fuel tank depending on the fuel used, the weather conditions and the tank venting system. In order to reduce the risk of burns and other personal injury from escaping gas vapor and fumes, remove the fuel filler cap on your power tool carefully so as to allow any pressure build-up in the tank to release slowly. Never remove the fuel filler cap while the engine is running. Select bare ground for fueling and move at least 10 feet (3 m) from the fueling spot before starting the engine. Wipe off any spilled fuel before starting your machine. Warning! Check for fuel leakage while refueling and during operation. If fuel leakage is found, do not start or run the engine until the leak is fixed and any spilled fuel has been wiped away. Take care not to get fuel on your clothing. If this happens, change your clothing immediately. SR 430, SR 450 7
