FUEL HANDLING

Fuelmix

IMPORTANT! The chain saw 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.

Always provide for good ventilation when handling fuel.

Petrol

•Use good quality unleaded or leaded petrol.

•The lowest octane recommended is 90.

•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.

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

Two-stroke oil

•For the best results use HUSQVARNA two-stroke oil, which is especially developed for chain saws. Mixing ratio 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%)-1:25 (4%).

•Never use two-stroke oil intended for water cooled outboard motors, so-called, 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 saw’s fuel tank.

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

•If the saw is not used for some time the fuel tank

should be emptied and cleaned.

The following applies to saws with catalytic converter

Petrol

Always use high grade unleaded petrol (minimum 95 ROZ). Leaded petrol will destroy the catalytic converter and it will no longer serve its purpose. The green fuel cap on saws fitted with catalytic converters means that only unleaded petrol can be used.

Two-stroke oil

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

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 saw near flammable substances or vapours.
