Onan generator maintenance checklist and kit prep

Use this Cummins maintenance checklist and kit guide to document model, GSN, kit, and service facts before generator support.

Owner-safe checklist

Record the Onan model, spec, serial or GSN, hour meter, maintenance interval, oil type noted by the manual, and any visible kit part number.
Stop the generator and do not restart if it runs rough, leaks, overheats, or has exhaust odor in or near the RV.
Use Cummins parts support, the operator manual, or qualified generator service for maintenance-kit fitment, fuel, exhaust, electrical, or parts decisions.
