FUEL HANDLING

Fuel mixture

!WARNING! the power cutter is fitted with a two-stroke engine and must always be run on a mixture of petrol and two-stroke oil. To ensure the correct mixture proportions it is important to measure the quantity of oil accurately. When mixing small amounts of fuel small discrepancies in the amount of oil has a great bearing on the proportions of the fuel mixture. Always provide good ventilation when handling fuel.

Petrol

•Use unleaded or quality leaded petrol.

•The lowest recommended

octane rating is 90. If you run the engine on a petrol with a lower octane rating than 90 so-called “knocking“ can occur. This leads to an increased engine temperature, which can result in a serious engine breakdown.

•Never use two-stroke oil intended for water cooled outboard motors, so-called outboard motor oil.

•Never use oil intended of four-stroke engines.

Mixture

• Always mix petrol and oil in a clean container intended for petrol.

• Always start by filling half the quantity of petrol required. Then add the entire oil quantity. Mix (shake) the fuel mixture. Fill the remaining quantity of petrol.

• Mix (shake) the fuel mixture carefully before filling in the machine‘s fuel tank.

• Do not mix fuel for more than approx. 2 months use.

• If the clearing saw is not used for a long period of time, the fuel tank should be emptied and cleaned.

Fuelling

!WARNING!The following precautions reduce the risk of fire:

•Do not smoke or place any sources of heat in the vicinity of the fuel.

•Never refuel when the engine is running.

•Open the fuel cap slowly when fuelling so that any over pressure is released slowly.

•Tighten the fuel cap carefully after refuelling.

•Always move the machine from the fuelling place before starting.

•Keep the handle dry, clean and free from oil and fuel.

• Clean around the fuel cap. Clean the fuel tank regularly. The fuel filter should be changed at least once per year Contamination in the tank can disrupt operations. Ensure that the fuel is well mixed by shaking the container before filling the tank.

• Always exercise care when filling the fuel. Move the power cutter at least three metres from the filling area before starting. Make sure the fuel cap is tightened.
