Maintenance Tips

• Oil & Filter Changes: Replace engine oil and filters every 100–200 hours or annually to prevent wear and maintain performance.
• App Connect Monitoring: Use the remote monitoring app to track performance, receive alerts, and detect issues early.
• Coolant System Care: Maintain proper coolant levels and flush periodically to prevent engine overheating.
• Air Filter & Spark Plugs: Clean or replace for reliable starts, efficient combustion, and optimal fuel economy.
• Weekly Exercise Cycle: Automatic test runs keep internal components lubricated and ready for power outages.
• Load Testing: Periodically run under load to ensure stable voltage, frequency, and full-capacity performance.
• Fuel System Check (NG/LP): Ensure consistent fuel supply and clean lines for uninterrupted operation.
• Battery & Electrical Connections: Check battery charge and terminal condition to guarantee fast automatic startup.
• Enclosure Maintenance: Keep the corrosion-resistant aluminum enclosure clean and properly ventilated to prevent overheating.
