Preventive maintenance is a set of planned and scheduled actions performed regularly on equipment, machinery, or facilities to prevent failures, reduce downtime, and extend asset life.

This type of maintenance is based on specific time intervals, equipment usage, or operating conditions, and typically includes activities such as inspections, cleaning, lubrication, adjustments, calibrations, and replacement of worn components.

The purpose of preventive maintenance is to ensure efficient, safe, and reliable operation, minimizing costs associated with unplanned repairs and increasing productivity.
