Preventive Maintenance Checklist
A Preventive Maintenance (PM) Checklist is a structured list of inspections and tasks performed at defined intervals to prevent equipment failure, reduce downtime, and extend machine life.
Purpose of a PM Checklist
- Prevent unplanned breakdowns
- Improve machine reliability & safety
- Standardize maintenance activities
- Support compliance & audits
- Improve MTBF and reduce MTTR
