FUEL HANDLING

Fuelmix

IMPORTANT! 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.

!Always provide for good ventilation when handling fuel.

Petrol

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.

•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.

•Use good quality unleaded or leaded petrol.

•The lowest octane recommended is 90 (RON). 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

Two-stroke oil

•For best results and performance use HUSQVARNA two-stroke engine oil, which is specially

formulated for our air-cooled two-stroke engines.

• Never use two-stroke oil intended for water-cooled engines, sometimes referred to as outboard oil (rated TCW).

• Never use oil intended for four-stroke engines.

Mixing ratio

1:50 (2%) with HUSQVARNA two-stroke oil or equivalent. 1:33 (3%) with oils class JASO FB or ISO EGB formulated for air-cooled, two- 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 cut-off saw is not used for some time the fuel tank should be emptied and cleaned.

•Keep the handle dry, clean and free from oil and fuel.

•Clean around the fuel cap. Clean the fuel tank regularly. The fuel filter should be changed at least once per year Contamination in the tank can disrupt operations. Ensure that the fuel is well mixed by shaking the container before filling the tank.

•Always exercise care when filling the fuel. Move the cut- off saw at least three metres from the filling area before starting. Make sure the fuel cap is tightened.
