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

CAUTION! Always use a good quality petrol/oil mixture (at least 90 octane). If your machine is equipped with a catalytic converter (see chapter on Technical data) always use a good quality unleaded petrol/oil mixture. Leaded petrol will destroy the catalytic converter and it will no longer serve its purpose.

Use low-emission petrol, also known as alkylate petrol, if it is available.

The lowest recommended octane rating is 90. If you run the engine on a petrol with a lower octane rating than 90 this can cause knocking. This leads to an increased engine temperature, which can result in serious engine damage.

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

Two-stroke oil

For best results and performance use HUSQVARNA two- stroke oil, which is specially formulated for our two-stroke engines. Mixture 1:50 (2%).

If HUSQVARNA two-stroke oil is not available, you may use another two-stroke oil of good quality that is 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 engines, sometimes referred to as outboard oil.

Never use oil intended for four-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.

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 working near flammable substances and/or vapours.

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

Clean the area around the fuel cap. Contamination in the tank can cause operating problems.

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