Preventive Maintenance
Scheduled maintenance performed to prevent equipment failures and extend asset life.
Full Definition
Preventive Maintenance (PM) is scheduled, routine maintenance performed on equipment to prevent unexpected failures, extend asset life, and maintain optimal performance. PM tasks are performed on a time-based or usage-based schedule (e.g., monthly filter changes, annual inspections, quarterly calibrations). PM programs reduce emergency repairs, downtime, and total maintenance costs. CMMS systems manage PM schedules and work orders.
