A backup generator is a vital piece of equipment that provides power during outages, ensuring your home or business stays functional when the grid goes down. However, to ensure it’s ready when you need it, regular generator maintenance is essential. Here are some practical tips and tricks to help you keep your generator in peak condition.
1. Perform Regular Oil Changes
Just like a car, a generator requires oil changes to keep its engine running smoothly. Follow the manufacturer’s guidelines for oil change intervals, which typically range from every 50 to 200 hours of operation. Use the recommended oil type, and check the oil level frequently to prevent damage from low lubrication.
2. Replace Air and Fuel Filters
Over time, air and fuel filters can become clogged, reducing the generator’s efficiency and potentially causing damage. Change the air filter at least once a year or after extended use. The fuel filter should also be replaced periodically to ensure clean fuel flows through the system.
3. Test Your Generator Regularly
Running your generator periodically (at least once a month) ensures it remains functional and helps identify any issues before an emergency arises. Let it run under load for at least 15–30 minutes to keep components lubricated and the battery charged.
4. Inspect the Battery
A dead battery is one of the most common reasons generators fail to start. Keep the battery terminals clean and free of corrosion, and test the voltage regularly. If your generator has a trickle charger, ensure it is working to maintain battery health.
5. Keep Fuel Fresh
Stale fuel can lead to engine problems and clogging. If your generator runs on gasoline, consider adding a fuel stabilizer to extend the shelf life. For diesel generators, keep the fuel tank full to prevent condensation and bacterial growth.
6. Check and Tighten Connections
Loose wires and connections can lead to electrical malfunctions or system failures. Periodically inspect all wiring, fasteners, and connectors, tightening any loose components as needed.
7. Store Your Generator Properly
If you use a portable generator, store it in a dry, ventilated area to protect it from the elements. If possible, cover it with a breathable tarp to prevent dust buildup while allowing airflow.
8. Schedule Professional Maintenance
While routine generator maintenance can be handled by the owner, scheduling an annual inspection with a professional technician ensures deeper diagnostics and servicing, such as checking the alternator, cooling system, and load testing.
By following these generator maintenance tips, you can extend the life of your unit and ensure it’s ready when you need it most. If you need professional maintenance or repairs, contact Fischer Electric for expert service and peace of mind.
