What is the primary purpose of preventive maintenance?

Preventive maintenance aims to prevent failures by performing planned, routine maintenance before issues appear. Through scheduled inspections, lubrication, adjustments, calibrations, and replacements based on time or usage, equipment stays within spec and operates reliably. The benefit is fewer unexpected breakdowns, safer operation, and lower overall life-cycle costs from reduced downtime and less severe repairs. Repairing after a failure is reactive maintenance, not preventive. Replacing all components on a fixed schedule is inefficient and can waste resources. Testing equipment in new environments is a different activity, not the primary purpose of preventive maintenance.
