Maintenance Tips to Ensure Your Generac Generator is Ready When Needed


Generac generators provide uninterrupted power during emergencies. To ensure your backup generator is always ready when needed, you must maintain it properly. Regular maintenance ensures optimal performance, extends the lifespan of your generator, and helps meet warranty requirements. This guide offers tips for maintaining Generac generators, drawing on the best practices for Generac generator upkeep.

Understanding Your Generac Generator’s Needs

The key to effective maintenance begins with understanding what your Generac unit requires. Each model has specific needs based on its kilowatt rating, engine size, and production year. The information here pertains to Generac home standby generators, but you should always refer to your owner’s manual to identify the correct steps before attempting DIY maintenance.

Generator Maintenance Checklist for Generac Units

Ready to keep your generator in top condition? Here are the essential maintenance steps for Generac power units:

  • Regularly change the oil and oil filter. For continuous use, check the engine oil level daily or before each use. Oil and oil filter replacements should occur every 200 to 400 hours of operation or every two to four years, whichever comes first. When changing the oil, use Generac 5W-20 GEO Full Synthetic oil to protect the engine.
  • Keep the air filters and vents clean. Clear your generator’s vents as needed to prevent overheating, maintain efficiency, and prevent carbon monoxide buildup. Then, replace the filters at 100 to 200 hours of operation.
  • Regularly check and replace the spark plugs. Perform valve adjustments as needed, except for certain models with hydraulic lifters.
  • Check the battery condition and charge level annually. Also, ensure the battery terminals are clean to prevent corrosion.
  • Inspect the fuel and oil lines for leaks and ensure they are in good condition, especially if you use the generator frequently.
  • Clean the sediment trap and check the enclosure louvers for dirt and debris to ensure proper ventilation.

Safety Precautions During Maintenance

When following this Generac generator maintenance guide, take personal safety seriously. Turn off the generator and let it cool down before working on it. Switch the main line circuit breaker off and remove the fuse as an extra precaution. Then, remove any jewelry or watches to avoid injury, and always wear safety glasses and gloves.
