Generators preventive maintenance

Start with the real operating context: duty, environment, consequence of failure, manufacturer guidance and the people who perform the work. A CMMS should preserve that context on the asset and place the relevant steps on each work order. It should not replace engineering judgment or a site-specific risk assessment.

Create a small initial task library, then improve intervals and evidence requirements from actual findings. The same model supports planned inspection, preventive replacement, calibration, lubrication, condition readings and corrective repair. Keep the result attached to the asset so the next decision uses history rather than memory.

A standby generator and a continuously operated unit may need different schedules and verification. Record engine hours, the site requirements and the manufacturer procedure before configuring a calendar or meter plan. No universal interval in this page overrides those requirements.

A metered asset can also have a fleet-style fuel record. Record the receipt currency, litres, date and engine-hour reading consistently. A fuel total does not prove available emergency runtime, fuel quality or successful load testing; retain those separate authorized records.

Install the edited checklist as a procedure and optionally create the first asset-linked work order. Add recurrence only after reviewing the interval. Assign the technician, due date and access window, then verify that the required observations are practical to record on site.

Complete one real task and ask a second authorized person to retrieve its findings. Review the source asset, parts, time and verification. Export the evidence and compare it with your current process before expanding the register. The template is an evidence structure, not an OEM service manual.

• Identify the exact equipment and current procedure revision
• Review operating duty, meter use and unresolved defects
• Assign the authorized service task and required evidence
• Record observations with units and measurement locations
• Retain parts, work performed and verification
• Review follow-up work and the next approved service trigger

Document likely failure modes, observable symptoms, safe response and the evidence required to return the asset to service. Review the list with experienced technicians rather than relying on a generic template.

Each record should state which asset and site were involved, the operating symptom, priority, responsible person, procedure version, safety context, readings, evidence, parts used, time spent, failure code when relevant, specific root cause, action taken and verification result. That is enough detail to support the next technician, a planner and a reliability review without forcing every person through the same interface.

PreventiveHQ snapshots procedure steps onto the work order and stops closure when required steps or close-out evidence are missing. It reports unavailable metrics when no trustworthy denominator exists. Those controls are more valuable than a polished chart built from “done” notes.
