Checking and changing the air filter

Generator owners should reference these articles before checking and changing the air filter:

Maintenance Schedule:
Air filter changes are listed as part of a generator's maintenance schedule. See the  Where Can I Find the Maintenance Schedule for My Generac Home Standby Generator? article for more information.

Maintenance Safety:
Owners should reference the  What Safety Precautions Should I Take when Performing Maintenance on My Generator? to ensure maintenance is performed in a safe manner.

Maintenance Kits:
Generac sells maintenance kits that bundle OEM parts for maintenance tasks. See the  What Are Generator Maintenance Kits? article for more information.

Authorized Service Dealers:
While generator owners can certainly perform maintenance tasks, scheduled maintenance tasks can also be completed by a certified service dealer. See the  How Can I Find a Generac Service Dealer in My Area? article for more information.

Consult the User Manual:
Owners should always reference the user manual for maintenance tasks. See  How Do I Find a Copy of My Home Standby Generator Owner's Manual and Spec Sheets? for more information.
