FUELS/REFUELING

Fuel and oil mixture

• The engine of the hedge trimmer is a high-efficiency two-stroke engine.
  • It is run with a mixture of fuel and two-stroke engine oil. The engine is designed for unleaded regular fuel with a min. octane value of 91 ROZ.
  • In case no such fuel is available, you can use fuel with a higher octane value. This will not damage the engine, but may cause poor operating behaviour.
  • A similar situation will arise from the use of leaded fuel.
  • To obtain optimum engine operation and to protect your health and the environment, only unleaded fuel should be used!
• For lubricating the engine use a two-stroke engine oil (quality grade: TSC-3), which is added to the fuel. The engine has been designed for use with MAKITA two-stroke engine oil and a mixture ratio of 50:1 only to protect the environment. In addition, a long service life and a reliable operation with a minimum emission of exhaust gases is guaranteed. It is absolutely essential to observe a mixture ratio of 50:1 (MAKITA 2-stroke engine oil), otherwise the reliable function of the hedge trimmer cannot be guaranteed.
• The correct mixture ratio:
  • Gasoline: Specified two-stroke engine oil = 50: 1 or
  • Gasoline: Other manufacturer’s two-stroke engine oil = 25: 1 recommended

NOTE:
For preparing the fuel-oil mixture, first mix the entire oil quantity with half of the fuel required in an approved canister which meets or exceeds all local code standards. Then add the remaining fuel. Thoroughly shake the mixture before filling it into the hedge trimmer’s tank. Do not add more engine oil than specified to ensure safe operation. It will only result in a higher production of combustion residues which will pollute the environment and clog the exhaust channel in the cylinder as well as the muffler. In addition, the fuel consumption will rise and the performance will decrease.

Handling petroleum products

• Utmost care is required when handling fuels. Fuels may contain substances similar to solvents. Refuel either in a well ventilated area or outdoors. Do not inhale fuel vapors, avoid any contact of fuel or oil with your skin.
• If your skin comes in contact with these substances repeatedly and for an extended period of time, it will desiccate.
• Various skin diseases may result. In addition, allergic reactions are known to occur. Eyes can be irritated by contact with oil, fuel etc.
• If oil, fuel, etc., comes into your eyes, immediately wash them with clear water.
• If your eyes are still irritated, see a doctor immediately!

Refuelling

• The engine must be switched off.
• Stop the engine during refuelling, keep away from flames and do not smoke.
• Take care not to spill either fuel or oil in order to prevent soil contamination.
• Clean the hedge trimmer immediately after fuel has been spilled.
• Do not spill fuel onto the engine. Wipe down if the fuel is spilled.
• Avoid any fuel contact with your clothes. Change your clothes instantly if fuel has been spilled on it (to prevent clothes catching fire).
• Inspect the fuel cap regularly making sure that it can be securely fastened and does not leak the fuel.
• Carefully tighten the fuel tank cap. Change location to start the engine (at least 3 meters away from the place of refuelling.)
• Never refuel in closed rooms. Fuel vapors accumulate at ground level. (Risk of explosions.)
• Transport and store fuel only in approved containers. Make sure the fuel stored is not accessible to children.
• Thoroughly clean the area around the tank cap to prevent dirt from getting into the fuel tank.
• Unscrew the plug and fill the tank with fuel. Use a gauze funnel to filter the fuel.
• Tightly screw on the plug by hand only.
• Clean around the screw plug and the tank after refuelling.
• Always wipe up any spilled fuel to prevent a fire.
