Maintaining Your Portable Generator
Periodic maintenance is essential for top performance and long generator life. Check your operator's manual for details of normal periodic maintenance. Under hot or dusty operating conditions, some maintenance operations should be performed more frequently. Keep a log of maintenance performed and the hours run. Recording maintenance helps you optimize service life and provides a basis for supporting warranty claims.
Maintenance, replacement, or repair of emission control devices and systems may be performed by any engine repair establishment or individual. However, warranty work must be completed by an authorized Cummins dealer or distributor. In all cases, you should contract a Cummins Onan Dealer and/or certified technician for advice.
