FUEL HANDLING

Fuelmix

IMPORTANT! The power cutter 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.

Gasoline

•This engine is certified to operate on unleaded gasoline.

•Use good quality unleaded gasoline.

•The lowest recommended

octane rating is 87. If you run the engine on lower octane rating than 87 so- called “knocking“can occur. This leads to an increased engine temperature, which can result in a serious engine breakdown.

•When working at continuous high revs a higher octane rating is recommended.

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.

• 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.

Two-stroke oil

•For the best results use HUSQVARNA two-stroke oil, which is especially developed for power cutters. Mixing ratio 1:50 (2%).

•Never use two-stroke oil intended for water cooled outboard engines, so-called, outboard oil.

•Never use oil intended for four-stroke engines.

• Always exercise care when

filling the fuel. Move the

power cutter at least three

metres from the filling area

before starting. Make sure

the fuel cap is tightened.

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 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.

•This engine is certified to operate on unleaded gasoline.
