This fuel contains fewer harmful chemicals compared to regular fuel, which decreases harmful exhaust fumes. The quantity of remains after combustion is lower with this fuel, which keeps the components of the engine clean.

To mix fuel

Gasoline

• Use good quality unleaded gasoline with a maximum of 10% ethanol content.

CAUTION: Do not use gasoline with an octane grade of less than 90 RON/87 AKI. The use of a lower octane grade can cause engine knocking, which causes engine damage.

Two-stroke oil

• For best results and performance use Husqvarna two-stroke oil.
• If Husqvarna two-stroke oil is not available, use a two-stroke oil of good quality for air-cooled engines. Speak to your servicing dealer to select the correct oil.

CAUTION: Do not use two-stroke oil for water-cooled outboard engines, also referred to as outboard oil. Do not use oil for four-stroke engines.

To mix gasoline and two-stroke oil

CAUTION:
Small errors can influence the ratio of the mixture drastically when you mix small quantities of fuel. Measure the quantity of oil carefully and make sure that you get the correct mixture.

1. Fill half the quantity of gasoline in a clean container for fuel.
2. Add the full quantity of oil.
3. Shake the fuel mixture.
4. Add the remaining quantity of gasoline to the container.
5. Carefully shake the fuel mixture.

CAUTION: Do not mix fuel for more than 1 month at a time.

To fill the fuel tank

WARNING: Obey the procedure that follows for your safety.

1. Stop the engine and let the engine become cool.

2. Clean the area around the fuel tank cap.

3. Shake the container and make sure that the fuel is fully mixed.

4. Remove the fuel tank cap slowly to release the pressure.
