A useful service record connects the initial condition, diagnosis, work performed and verified outcome. It supports handover, quality management and later investigation of recurring faults.
| Record field | What to capture |
|---|---|
| Identification | Machine and component ID, date, operating hours and responsible personnel. |
| Initial condition | Observed symptoms, visual findings and measurements with units and operating conditions. |
| Diagnosis | Suspected or confirmed cause and the evidence supporting it; distinguish observation from interpretation. |
| Work performed | Cleaning, adjustments and replaced parts, including part numbers and relevant drawing revisions. |
| Verification and release | Test conditions, results, acceptance criteria, remaining issues and the responsible person's dated confirmation. |
Training example, not an actual service event. Machine MW-DEMO, housing H1: water observed in the outer seal chamber during inspection. A blocked drain was found; bearing damage was not confirmed.
Action: cleared the drain, cleaned the chamber and inspected the outer seal. No parts replaced. Result: drainage restored during the check; loaded-operation verification remains pending. Return to production has not been approved.
