FUEL HANDLING

Fuel

CAUTION! The machine is equipped with a two-stroke engine and must always been run using a mixture of petrol and two- stroke engine oil. It is important to accurately measure the amount of oil to be mixed to ensure that the correct mixture is obtained. When mixing small amounts of fuel, even small inaccuracies can drastically affect the ratio of the mixture.

WARNING! Always ensure there is adequate

!ventilation when handling fuel.

Petrol

Use good quality unleaded or leaded petrol.

The lowest octane recommended is 90 (RON). If you run the engine on a lower octane grade than 90 so-called knocking can occur. This gives rise to a high engine temperature, which can result in serious engine damage.

Two-stroke oil

For best results and performance use HUSQVARNA two- stroke engine oil, which is specially formulated for our air- cooled two-stroke engines.

Never use two-stroke oil intended for water-cooled engines, sometimes referred to as outboard oil (rated TCW).

Never use oil intended for four-stroke engines.

Mixing ratio

1:50 (2%) with HUSQVARNA two-stroke oil or equivalent.

1:33 (3%) with oils class JASO FB or ISO EGB formulated for air-cooled, two-stroke engines.

Mixing

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

Always start by filling half the amount of the petrol to be used. Then add the entire amount of oil. Mix (shake) the fuel mixture. Add the remaining amount of petrol.

Mix (shake) the fuel mixture thoroughly before filling the machine’s fuel tank.

Do not mix more than one month’s supply of fuel at a time.

If the machine is not used for some time the fuel tank should be emptied and cleaned.

Fuelling

WARNING! Taking the following precautions,

!will lessen the risk of fire:

Do not smoke or place hot objects near fuel.

Always shut off the engine before refuelling.

When refuelling, open the fuel cap slowly so that any excess pressure is released gently.

Tighten the fuel cap carefully after refuelling.

Always move the machine away from the refuelling area before starting.

Keep the handle dry and free from oil and fuel.

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

Always exercise care when refilling the fuel. Move the machine at least three metres from the fuelling area before it is started. Check that the fuel cap is tightened correctly.

Clean around the fuel cap. Clean the fuel and oil tank regularly. The fuel filter should be changed at least once a year. Contamination in the tanks causes malfunction.
