FUEL HANDLING

Fuel

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

Gasoline

•This engine is certified to operate on unleaded gasoline.

•Use good quality unleaded gasoline.

•The lowest octane recommended is 87. If you run the engine on a lower octane than 87 it can result in knocking. This gives rise to a high engine temperature, which can result in serious engine damage.

•When working with continuous high revs (e.g. limbing) a higher octane 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%).

•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 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.

•This engine is certified to operate on unleaded gasoline.

Chain oil

•The chain lubrication system is automatic and we recommend the use of special oil (chain oil) with good adhesion characteristics.

•In countries where no special chain oil is available, EP90 transmission oil can be used.

•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.
