FUEL HANDLING

Fuel mix

NOTE!

The pruning saw is fitted with a two-stroke engine and must always be run on a mixture of petrol and two-stroke oil. To ensure the correct mixture proportions it is important to measure the quantity of oil accurately. When mixing small amounts of fuel small discrepancies in the amount of oil have a big effect on the proportions of the fuel mixture.

!WARNING!

Always provide good ventilation when handling fuel.

Petrol

• Use unleaded or leaded high octane petrol mixed with oil.

•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.

•For work with continuously high revs a higher octane rating is

recommended.

Twostroke oil

• For the best results use Husqvarna twostroke oil. Mixing ratio 1:50 (2%).

•If Husqvarna twostroke 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 twostroke oil

intended for water cooled outboard engines, 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 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 fuel tank.

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

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

Fuelling

!WARNING!

The following precautions reduce the risk of fire:

Do not smoke or place any sources of heat in the vicinity of the fuel. Never refuel when the engine is running. Always stop the engine and let it cool for a few minutes before refuelling. Open the fuel cap slowly when fuelling so that any over pressure is released slowly. Tighten the fuel cap carefully after refuelling. Always move the machine from the fuelling place before starting.
