Diesel Generator Preventive Maintenance Checklist

A reliable generator needs scheduled inspection even when it runs for only a few hours. Daily checks include engine oil, coolant, fuel leaks, battery voltage and warning lights.

Weekly checks should include a short loaded run, cable inspection, exhaust condition and charger operation. Service intervals depend on engine hours, oil grade, dust and ambient temperature.

Record every service date and running-hour reading. A clear maintenance history helps diagnose faults early and protects the generator investment.
