13FUELS/REFUELINGHandling fuelUtmost care is required when handling fuel. Fuel may contain substancessimilar to solvents. Refuel either in a well ventilated room or outdoors. Donot inhale fuel vapors, avoid any contact of fuel or oil with your skin.Mineral oil products degrease your skin. If your skin comes in contact withthese substances repeatedly and for an extended period of time, it willdesiccate. Various skin diseases may result. In addition, allergic reactionsmay occur. Eyes can be irritated by contact with oil. If oil comes into youreyes, immediately wash them with clear water. If your eyes are still irritated,see a doctor immediately.Fuel and oil mixtureThe engine of the brush cutter is a high-efficiency two-stroke engine. It is runwith a mixture of fuel and two-stroke engine oil. The engine is designed forunleaded regular fuel with a min. octane value of 91 RON. In case no suchfuel is available, you can use fuel with a higher octane value. This will notaffect the engine, but may cause poor operating behaviour.A similar situation will arise from the use of leaded fuel. To obtain optimumengine operation and to protect your health and the environment, only unleadedfuel should be used!For lubricating the engine use a two-stroke engine oil (quality grade: TC-3),which is added to the fuel. The engine has been designed for use withspecified two-stroke engine oil and a mixture ratio of only 25:1 to protect theenvironment. In addition, a long service life and a reliable operation with aminimum emission of exhaust gases is guaranteed. It is absolutely essentialto observe a mixture ratio of 25:1 (specified 2-stroke engine oil), as otherwisereliable function of the brush cutter cannot be guaranteed.The correct mixture ratio:Mix 25 parts gasoline with 1 part specified 2-stroke engine oil (see table onright).NOTE: For preparing the fuel-oil mixture first mix the entire oil quantity with halfof the fuel required, then add the remaining fuel. Thoroughly shakethe mixture before filling it into the brush cutter tank. It is not wise toadd more engine oil than specified to ensure safe operation.This will only result in a higher production of combustion residues whichwill pollute the environment and clog the exhaust channel in thecylinder as well as the muffler. In addition, the fuel consumption willrise and the performance will decrease.The engine must be switched off.– Thoroughly clean the area around the fuel filler cap, to prevent dirt fromgetting into the fuel tank.– Unscrew the fuel filler cap and fill the tank with fuel.– Tightly screw on the fuel filler cap.– Clean screw fuel filler cap and tank after refueling.Storage of FuelFuel cannot be stored for an unlimited period of time.Purchase only the quantity required for a 4 week operating period. Only useapproved fuel storage containers.Gasoline 25:11000 mL (1 L) 40 mL5000 mL (5 L) 200 mL10000 mL (10 L) 400 mLObserve the Safety Instructions on page 4.125
