What Maintenance Tips Can Help Ensure Your Generator is Ready for a Storm?

To ensure your generator is ready for a storm, regular maintenance is essential. Proper upkeep will enhance performance and reliability during power outages.

  1. Inspect Fuel System
  2. Change Oil Regularly
  3. Check Batteries
  4. Test Run the Generator
  5. Keep the Generator Clean
  6. Store Properly
  7. Use Surge Protectors

Regular maintenance improves generator performance. Each of these maintenance tasks plays a critical role in ensuring your generator operates effectively when needed.

  1. Inspect Fuel System:
    Inspecing the fuel system involves examining hoses, fittings, and the fuel tank. This inspection helps identify leaks or damage that could impair performance. Contaminated fuel can also harm the generator. A clean fuel system ensures that the engine runs smoothly, preventing failures during storms.

  2. Change Oil Regularly:
    Changing the oil regularly keeps the engine lubricated and reduces wear. Dirty oil can lead to engine overheating and damage. According to generators’ manufacturers, it’s best to change the oil after the first 20-50 hours of use and then every 100 hours afterward. This practice can significantly extend the generator’s lifespan.

  3. Check Batteries:
    Checking the battery ensures adequate charge and functionality. A weak battery can prevent the generator from starting. Regularly inspecting battery terminals for corrosion and testing the charge level helps maintain proper performance. Experts recommend replacing batteries every one to two years to guarantee efficiency.

  4. Test Run the Generator:
    Running the generator allows you to test its performance. This task confirms that it starts smoothly and operates correctly under load. The American Red Cross advises running the generator for 30 minutes every month to keep it in working condition. This practice helps identify potential issues before a storm approaches.

  5. Keep the Generator Clean:
    Cleaning the generator prevents dirt and debris from entering sensitive components. Keeping it free from dust can help maintain airflow and cooling, crucial for optimal operation. Regularly wiping down the exterior and removing any accumulated debris is advisable.

  6. Store Properly:
    Proper storage prevents environmental damage and mechanical issues. Ideally, store the generator in a cool, dry, and sheltered area, away from extreme temperatures and moisture. Using a cover designed for generators can also protect against dust and debris.

  7. Use Surge Protectors:
    Using surge protectors can guard against voltage spikes during storms. These protectors shield the generator’s electrical components from potential damage due to power fluctuations. Installing a surge protector can prevent costly repairs and maintain reliability.

Regular maintenance remains vital for the functional integrity of your generator, especially with approaching storms.
