FUEL HANDLING

Fuel mixture

NOTE!

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

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

gasoline.

• 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 breakdown.

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 machine‘s fuel tank.

Do not mix more than max. one month’s supply of fuel.

If the machine 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 machine 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 place before starting.

• 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 clearing saws and chain saws.

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.

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.
