If you want top performance and a long life for your Cummins generator, periodic maintenance is essential.

Generate Productivity, Not Downtime

Simply follow these five easy tips...

  1. Follow your operator's manual details regarding normal periodic generator maintenance.  (This is your best "preventantive medicine.")
  2. If your generator(s) operate in hot or dusty conditions, perform maintenance operations more frequently.
  3. Keep a log of the maintenance you perform and the hours run.  This helps optimize service life and provide a basis for supporting warranty claims.
  4. For maintence, replacement or repair of emission control devices and systems, you can use any engine repair establishment or individual.  But for a warranty work, always use an authorized Cummins dealer or distributor.
  5. No matter what work you need done, always contact a Cummins dealer and/or certificed technician for advice.
