The McCulloch MAC-CAT 435 requires a fuel mixture of 50:1. This means that for every 50 parts of gasoline, you should add 1 part of two-cycle engine oil.
Mixing Instructions
1. Measure out the desired amount of gasoline.
2. Add the two-cycle engine oil to the gasoline.
3. Shake the mixture thoroughly to ensure that the oil is evenly distributed.
Important Notes
- Always use fresh fuel when operating your McCulloch MAC-CAT 435. Old fuel can cause damage to the engine.
- Do not overfill the fuel tank. Overfilling can cause the engine to run rich, which can lead to decreased performance and increased emissions.
- If you are using a fuel stabilizer, be sure to add it to the fuel mixture before storing your chainsaw for an extended period of time.
