5.1 Fuel and Chain Oil Preparation
This chainsaw requires a mixture of gasoline and 2-stroke engine oil. Always use fresh, high-quality unleaded gasoline and a premium 2-stroke engine oil specifically designed for air-cooled engines. Refer to the engine oil manufacturer's instructions for the correct mixing ratio (typically 50:1 or 25:1).
- Measgachadh connaidh: Mix gasoline and 2-stroke oil in a separate, approved fuel container. Shake well before filling the chainsaw's fuel tank.
- Ola slabhraidh: Fill the chain oil tank with high-quality bar and chain oil. Do not use waste oil or motor oil, as this can damage the pump and chain.

- Fit the chain onto the sprocket and around the guide bar, ensuring the cutting edges face the correct direction.
- Cuir am bàr-treòrachaidh air na studan, a’ co-thaobhadh prìne teannachaidh an t-slabhraidh ris an toll sa bhàr-treòrachaidh.
