Additional Tips
- Always use fresh, unleaded gasoline. Ethanol or reformulated fuels such as E85 or E10 can cause damage to the saw.
- For best results, use McCulloch 2-cycle motor oil or a good quality 2-cycle oil specifically formulated for air-cooled, 2-stroke engines.
- Do not over-oil the fuel mixture; this can lead to engine damage.
- Always shake the fuel container vigorously before using it to ensure the fuel and oil are thoroughly mixed.
- Avoid filling the fuel tank to the brim; leave some room for expansion.
- Never refuel the saw while the engine is running or hot.
- Store fuel in a cool, dry place.
