FUEL HANDLING

Fuel

Note! The machine is equipped with a two-stroke engine and must always be run using a mixture of gasoline and two- stroke 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.

Gasoline

This engine is certified to operate on unleaded gasoline.

Use good quality unleaded gasoline. Engines equipped with catalytic converters must be run on unleaded fuel mixtures.

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

When working with continuous high revs (e.g. limbing) a higher octane is recommended.

Environment fuel

HUSQVARNA recommends the use of alkylate fuel or environment fuel for four-stroke engines blended with two- stroke oil as set out below. Note that carburetor adjustment may be necessary when changing the type of fuel (see instructions under the heading Carburetor).

Running-in

Avoid running at a too high speed for extended periods during the first 10 hours.

Two-stroke oil

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

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 ratio

For all engines: 1:50 (2%)

Mixing

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

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

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.

Chain oil

We recommend the use of special oil (chain oil) with good adhesion characteristics.

Never use waste oil. This results in damage to the oil pump, the bar and the chain.

It is important to use oil of the right grade (suitable viscosity range) to suit the air temperature.

In temperatures below 0°C (32°F) some oils become too viscous. This can overload the oil pump and result in damage to the oil pump components.

Contact your service agent when choosing chain oil.
