Automatic Standby Generator Owner’s Manual 21
Section 4 Maintenance
NOTE: Proper maintenance and proper and safe operation is crucial to the life of the generator. Genuine Generac parts MUST be used
to ensure warranty coverage
NOTE: Since most maintenance alerts occur at the same time (most have two year intervals), only one will appear at any one time.
Clearing one will cause the next active alert to be displayed.
All service work to this generator must be performed by a qualified service person only.
4.1 — Performing Scheduled Maintenance
It is important to perform Maintenance as specified in the Service Schedule for proper generator operation and to ensure that the generator com-
plies with the applicable emission standards for the duration of its useful life. Service and repairs may be performed by any qualified service per-
son or repair shop. Additionally, emissions critical maintenance must be performed as scheduled in order for the Emissions Warranty to be valid.
Emissions critical maintenance consists of servicing the air filter and spark plugs in accordance with the Service Schedule. The controller will
prompt for Schedule A or Schedule B maintenance to be performed. Schedule A maintenance consists of the oil, oil filter and tune-up. Schedule
B maintenance includes the oil, oil filter, tune-up, air cleaner, spark plug(s) and valve clearance.
