Quick Answer
Regularly check and maintain the oil levels, air filter, and spark plugs to ensure a safe and efficient operation of your whole-house generator. Additionally, inspect the electrical connections and consider having a professional inspect the unit annually. Follow the manufacturer's instructions and recommended maintenance schedule.
Maintenance Schedule
Establish a regular maintenance routine to ensure the longevity and safety of your whole-house generator. Typically, this includes checking the oil levels every 25 hours of usage, replacing the air filter every 100 hours, and inspecting the spark plugs every 200 hours. You should also schedule an annual professional inspection to identify any potential issues before they become major problems.
Electrical Connection Checks
Verify the electrical connections to the generator are secure and not damaged. This includes the connections to the main electrical panel and any transfer switches. Use a voltage tester to ensure the connections are properly connected and not sparking. Consider labeling the connections to avoid confusion during future maintenance.
Storage and Winterization
If you plan to store the generator during periods of inactivity, follow the manufacturer’s storage instructions. This usually includes draining the fuel tank to prevent stale fuel, cleaning the air filter, and applying a rust inhibitor to the metal components. For generators that will not be used during the winter months, consider using a fuel stabilizer and keeping the generator in a well-ventilated area to prevent moisture buildup.
