FUEL HANDLING

Fuel

NOTE!

The machine is fitted with a two-stroke engine and must always be run on a mixture of petrol and two-stroke oil. It is important to measure the quantity of oil accurately, to ensure the correct mixture ratio. Small discrepancies in the amount of oil have a great bearing on the proportions of the fuel mixture when mixing small amounts of fuel.

!WARNING!

Always provide good ventilation when handling fuel.

Petrol

NOTE!

Always use an oil-mixed quality petrol (at least 90 octane). If your machine is equipped with a catalytic converter, (see “technical data”) an unleaded, oil mixed quality petrol should always be used. A leaded petrol will destroy the catalytic converter.

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 produced for brush cutters and chain saws. 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: 1:25 (4%).

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 more than max. one month’s supply of fuel.

If the brush cutter 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. 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 operations.

Ensure that the fuel is

well mixed by shaking the container before filling the tank.

• Always use a fuel
