Owner’s Manual for Stationary Diesel Generators

5.3 — Service Maintenance Intervals

NOTE: 

Use only Genuine Generac parts to ensure warranty coverage.

All generator service must be performed by a qualified service person only.

It is important to perform all maintenance at the interval specified in the Service Maintenance Schedule. This 

ensures safe and proper operation, as well as compliance with applicable emissions standards. Critical emissions 
maintenance must be performed for the Emissions Warranty to remain valid. Service and repairs may be performed by 
any qualified service technician or repair shop.
Observe the maintenance tasks and intervals shown in the table below.

NOTE: If the unit reaches a Schedule A or Schedule B maintenance interval with 900 to 999 total hours, have 
an authorized service provider perform the Schedule C maintenance tasks as well (and reset the A-B-C/Year 
maintenance schedule counter).
