At 250 hours, service work usually includes filters, oil, belts, battery terminals, coolant concentration and control panel checks.
The service interval should be shortened in hot, dusty, humid or high-load environments.
Always inspect the generator under load after maintenance. No-load testing alone may miss cooling or fuel delivery issues.
Field Checks
- Running hours, last service date and current alarm history.
- Photos of filters, batteries, coolant level, controller screen and nameplate.
- Load percentage during testing and whether the generator is standby or prime use.
Checklist
- Replace filters
- Check coolant
- Clean radiator
- Inspect battery
- Load test after service
Common Mistakes
- Changing parts without recording the original part number and engine model.
- Only servicing the engine while ignoring battery, charger, radiator and ATS.
- Running standby units for years without load testing.
