Air Cooled Generator Service/Maintenance Schedule

Regular maintenance is essential for ensuring the reliable operation of your air-cooled generator.


Below is a recommended service schedule:

Daily Maintenance (If running Continuously)

  • Check the oil level and condition. Top up or replace the oil as needed.
  • Check the generator's status indicators for any warning lights or error codes.
  • Inspect the fuel system for leaks or signs of damage.
  • Inspect the surrounding area for debris or obstructions that could affect airflow.
  • Ensure that the generator's enclosure is clean and free of dirt or debris.
  • Inspect the air filter and clean or replace it if necessary.
  • Inspect the spark plug and replace it if worn or fouled.
  • Check the battery terminals for corrosion and clean them if necessary.

Every 6 Months Maintenance

  • Inspect the fuel system for leaks or signs of damage.
  • Inspect the generator's wiring and connections for any signs of wear or damage.

Annually Maintenance

  • Change the oil and oil filter.
  • Inspect and clean the cooling fins and engine components for any buildup of dirt or debris.

We recommend having a certified Generac technician do annual service every year. While some of the units will not need an air filter, spark plug or battery every year. We can catch many small problems before they become a major problem. We want to ensure that your unit is ready to run when there is an outage. Some outages may be extended so waiting 2 years to do maintenance can be dangerous if you get a big storm while your unit is close to needing a maintenance.   This schedule is for most air cooled units and liquid cooled units will add more items to this list.
