4. Opsætning og brændstofpåfyldning
Fuel Mixture (40:1 Ratio):
This unit requires a mixture of unleaded gasoline and 2-cycle engine oil at a 40:1 ratio. This means for every 40 parts of gasoline, add 1 part of 2-cycle oil.
- Brug frisk, ren, blyfri benzin med et oktantal på 87 eller højere.
- Use a high-quality 2-cycle engine oil specifically designed for air-cooled engines.
- Mix the fuel and oil thoroughly in a separate, approved fuel container before pouring into the blower's fuel tank.
