Oil and filter service should be done with the correct grade, quantity and part numbers for the engine model. Running the engine briefly before draining can help oil flow, but hot surfaces require care.
Replace filters according to engine instructions and inspect old filters for abnormal metal particles, fuel contamination or sludge.
After service, start the generator, check pressure, inspect leaks and record operating data.
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
- Confirm oil grade
- Drain safely
- Replace filters
- Check leaks
- Record 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.
RFQ Data to Prepare
