FUEL HANDLING

Fuel mixture

NOTE!

The edger is ﬁtted with two-stroke engines 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 have a great bearing on the proportions of the fuel mixture.

!WARNING!

Always provide good ventilation when handling fuel.

Petrol

• Always use unleaded, oil mixed, quality petrol! (at least 90 octane). Leaded petrol will destroy the catalytic converter and it will no longer serve its purpose.

• 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.

• When working at continuous high revs a higher octane rating is recommended.

Two-stroke oil

• For the best results use HUSQVARNA two stroke oil, which has been specially developed for 2-stroke engines. Mixing ratio 1:50 (2%).

• If HUSQVARNA two stroke oil is not available you can use a high quality two-stroke oil intended for air cooled engines. Contact your dealer when selecting an oil. Mixing ratio: 1:33 (3%).

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

•Never use oil intended for 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 machineʼs fuel tank.

•Do not mix fuel for more than max. one month's supply of fuel.

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

!WARNING!

The catalytic converter mufﬂer becomes very hot during and after use. This also applies during idling. Be aware of the ﬁre hazard, especially when handling the saw near ﬂammable substances 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 area before starting.

• Clean around the fuel cap. Contamination in the tank can disrupt operations.

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