Tips & Procedures for day-to-day operation of your Cummins Onan Marine Generator

Here are some good general tips. You’ll find other helpful information in your Operator’s Manual which can be supplied by Cullys (just contact our office!)

  • Inspect and clear sea water strainers of debris, do not wait under they clog. Lack of inspection could result in seawater pump impeller damage
  • Inspect area around generator set to be sure nothing has moved or been knocked loose (rags, cleaning equipment, tools, spare parts, etc.) while underway, that could block air inlet or outlet or damage wires or hoses
  • Inspect generator est for fluid levels, leaks, and required service intervals based on operation hours and perform any identified maintenance as necessary
