FUEL HANDLING

Fuel mixture

NOTE!

The edger is ﬁtted with two-stroke engines and must always be run on a mixture of gasoline 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.

!WARNING!

Always provide good ventilation when han- dling fuel.

Gasoline

NOTE!

Always use high grade unleaded oil mixed gasoline (minimum 87 RON). Leaded fuel will destroy the catalytic converter and it will no longer serve its purpose.

• This engine is certiﬁed to operate on unleaded gaso- line.

• The lowest recommended octane rating is 87. If you run the engine on lower octane rating than 87 so-called “knocking“ can occur. This leads to an increased engine temperature, which can result in a serious engine break- down.

•When working at continuous high revs a higher octane rat- ing is recommended.

Two-stroke oil

• For the best results use HUSQVARNA two-stroke oil, which has been specially developed for two-stroke engines.

Mixing ratio 1:50 (2%).

• 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 gasoline and oil in a clean container intended for fuel.

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

•Mix (shake) the fuel mixture carefully before ﬁlling in the machineʻs fuel tank.

•Do not mix more than max. one monthʼs supply of fuel.

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

•This engine is certiﬁed to operate on unleaded gasoline.

!WARNING!

The catalytic converter mufﬂer gets very hot during and after use. This also applies during idling. Be aware of the ﬁre hazard, especially when handling the saw near ﬂammable sub- stances or vapours.

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. Always stop the engine and let it cool for a few minutes before refuelling. 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.

•Clean around the fuel

cap. Contamination in the tank can disrupt opera- tions.

• Ensure that the fuel is well mixed by shaking the container before ﬁlling the tank.
