FUELS/REFUELLING

Handling fuel

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

Fuel and oil mixture

The engine of the Edging 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 RON. In case no such fuel is available, you can use fuel with a higher octane value. This will not affect 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: TC-3), which is added to the fuel. The engine has been designed to use specified two-stroke engine oil at mixture ratio of 50:1 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 (specified 2-stroke engine oil), as otherwise reliable function of the Edging 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, then add the remaining fuel. Thoroughly shake the mixture before filling it into the Edging trimmer tank. It is not wise to add more engine oil than specified to ensure safe operation.

This 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.

Refuelling

The engine must be switched off.

–Thoroughly clean the area around the fuel filler cap (2), to prevent dirt from getting into the fuel tank (1).

–Unscrew the fuel filler cap (2) and fill the tank with fuel.

–Tightly screw on the fuel filler cap (2).

–Clean screw fuel filler cap (2) and tank after refueling.

Storage of Fuel

Fuel cannot be stored for an unlimited period of time.

Purchase only the quantity required for a 4 week operating period. Only use approved fuel storage containers.
