Investing a backup generator ensures your home remains powered during unexpected outages. But, like any equipment, they require regular upkeep to ensure they function properly when you need them most.

To ensure your generator performs reliably when you need it, it’s essential to perform regular maintenance. This guide covers key maintenance tasks to keep your generator in top shape.

1. Regular Inspections: Start with routine visual inspections of your generator. Regularly examine the exterior for any signs of damage, such as cracks or leaks. Look for loose or frayed wires and check that all components are securely fastened. Inspecting the generator for physical damage can help identify problems before they become serious issues.

Additionally, check to ensure that all electrical connections are secure and free from corrosion. Loose connections can cause inefficient operation or even failure. Tighten any loose connections and clean any corrosion with a wire brush and electrical contact cleaner. Regularly checking these connections helps maintain reliable operation and safety.

2. Routine Oil Changes: The engine oil in your generator lubricates its moving parts, reducing friction and preventing wear. Over time, oil degrades and becomes less effective, which can lead to engine damage. Regular oil changes can ensure smooth operation and longevity of your backup generator.

Most generators require an oil change every 100 to 150 hours of operation or at least once a year, whichever comes first. Check your generator’s manual for specific recommendations based on usage and environmental conditions.

Changing Oil Procedure: To change the oil, first, run the generator for a few minutes to warm it up. This makes the oil flow more easily. Turn off the generator and allow it to cool slightly. Locate the oil drain plug, place a container underneath, and drain the old oil. Replace the oil filter if your generator has one. Refill with new oil, making sure to use the type and amount specified in the manual. Check the oil level with the dipstick and add more if needed.

3. Air Filter Maintenance: The air filter keeps dirt, dust, and debris from damaging crucial components of the generator. A clogged filter can restrict air flow, causing the engine to work harder and potentially leading to overheating or reduced performance.

Depending on usage, you may need to clean or replace the air filter every 25 to 50 hours of operation. If the filter is only slightly dirty, you can clean it with compressed air or a vacuum cleaner. For more severe clogging or damage, replace the filter with a new one. Follow the manufacturer’s recommendations for maintenance and replacement intervals.

4. Battery Care: The battery powers the generator’s start-up process. Regularly check the battery’s condition to ensure it is in good working order. Look for signs of corrosion on the terminals, such as a white or blue powdery substance. Corrosion can hinder the battery’s performance and make starting the generator difficult.

If the battery does not hold a charge or shows signs of damage, it may need replacement. Most batteries need replacing every 2 to 3 years, but this can vary based on usage and environmental conditions.

5. Fuel System Maintenance: Regularly check the fuel lines for signs of wear, cracks, or leaks. Damaged fuel lines can lead to fuel spills or reduced engine performance. Replace any damaged or worn fuel lines promptly to maintain safe and efficient operation. Over time, fuel can degrade and cause starting problems or damage the engine. If the fuel in your generator is older than a few months, it’s best to drain it and refill it with fresh fuel.

6. Regular Testing: Regular testing helps identify any issues that need addressing before a real emergency occurs. To test your generator, turn it on and let it run for about 10 to 15 minutes. This allows the engine to reach its normal operating temperature and ensures all components are functioning. Check for any unusual noises, vibrations, or warning lights. If the generator doesn’t start or runs poorly, address the issues promptly to avoid problems during an actual outage.

7. Professional Servicing: While it might be tempting to maintain your backup generator all on your own, some maintenance tasks and repairs are best handled by professionals. If you encounter problems that you cannot resolve yourself or if the generator requires a thorough inspection, contact a qualified technician, like KingAire.
