Configuració

1. Mescla de combustible i oli

The Stiga SP 375 Q uses a 2-stroke gasoline engine. It requires a specific mixture of unleaded gasoline and 2-stroke engine oil. Refer to the engine oil manufacturer's instructions for the correct mixing ratio, typically 50:1 (2% oil) or 25:1 (4% oil) depending on the oil type. Always use fresh, high-quality fuel and oil.

• Mix the fuel and oil in a separate, approved fuel container.
• Shake the container thoroughly to ensure proper mixing.
• Fill the chainsaw's fuel tank carefully, avoiding spills.

2. Chain Lubrication Oil

The chainsaw features an automatic oil pump for chain lubrication. Fill the chain oil reservoir with high-quality bar and chain oil. Do not use waste oil or motor oil, as this can damage the pump and chain.

3. Chain Installation and Tensioning

Ensure the guide bar and chain are correctly installed. The Stiga SP 375 Q features tool-less chain tensioning.

• Loosen the side cover knob.
• Adjust the chain tensioning screw until the chain fits snugly against the guide bar, but can still be pulled freely by hand. There should be a small gap (approx. 2-3 mm) between the chain and the underside of the guide bar when lifted.
• Tighten the side cover knob securely.
• Check chain tension again after a few cuts, as new chains can stretch.
