Schedule A maintenance
Home standby generators require specific maintenance tasks to be completed at different intervals to prolong the life of the generator and keeping it in good working order. Schedule A maintenance refers to a collection of tasks that should be performed every two years or every 200 hours of operation, whichever comes first.
When the Schedule A maintenance interval has been reached, the status light on the side of the generator will turn yellow: What Does a Shining Yellow LED Light Mean on the Control Panel of My Generator?
Environment

Schedule A maintenance tasks
Note: Generators that operate in extremely hot or cold environments <40°F (<4.4°C) or >85°F (>29.4°C) will require an oil and oil filter change after every 100 hours of run time since last service, due to the strain that extreme environments put on the engine and fuel system.
Who can perform maintenance?
Homeowners can perform regular maintenance tasks as outlined in their generator's user manual. Alternatively, homeowners can contact a Generac authorized service dealer for help. See Where Can I Find a Company to Perform Standard Maintenance On My Generator? for more information.
Regardless of who performs the maintenance, maintenance records must be kept for future reference. The Mobile Link for Generators app offers functionality to record and track maintenance tasks. See the Viewing, Adding, Deleting, & Exporting Maintenance Schedule Records in Mobile Link article for more information.
