Maintenance Tips
- Regular Oil Changes: Adhere to Denyo's recommended oil change intervals (typically every 250-500 hours, depending on the model and operating conditions) using the specified oil type. Check the oil level daily before operation.
- Filter Maintenance: Inspect and replace air, fuel, and oil filters according to the manufacturer's recommendations. Clogged filters can significantly reduce performance and fuel efficiency. Use genuine Denyo filters or reputable aftermarket alternatives to ensure proper filtration and engine protection.
- Cooling System Checks: Regularly inspect the coolant level and condition. Flush and replace the coolant every two years or as recommended by Denyo to prevent corrosion and overheating.
- Inspect and Maintain Wiring & Connections: Routinely check wiring for damage or wear. Ensure all electrical connections are clean and tight to prevent power loss and potential hazards.
- Fuel System Care: Use clean, high-quality fuel and add a fuel stabilizer if the generator will be stored for an extended period. Regularly drain the fuel tank to remove any water or sediment.
