Preventive Maintenance is a planned approach to keeping machines and equipment in good working condition. Think of it like regular health check-ups for machinery - just as people go to doctors for check-ups before getting sick, equipment gets regular inspections and upkeep to prevent breakdowns. This includes routine tasks like cleaning, lubricating, adjusting, and replacing worn parts before they fail. Companies value this approach because it reduces unexpected breakdowns, saves money on repairs, and helps equipment last longer. Other names for this include "planned maintenance," "preventative maintenance," or "PM" for short.
