prevention , Systematic inspection, detection, and correction of incipient failures, before they become actual or major failures. Contrasted with corrective maintenance. It is a maintenance that is regularly performed on an equipment to lessen the likelihood of it failing. Preventative maintenance is performed while the equipment is still working, so that it does not break down unexpectedly. Preventative maintenance is planned so that any required resources are available. The maintenance is scheduled based on a time or usage trigger. A typical example of an asset with a time based preventative maintenance schedule is an air-conditioner which is serviced every year, before summer. A typical example of an asset with a usage based preventative maintenance schedule is a motor-vehicle which might be scheduled for service every 10,000km. Preventative maintenance is more complex to coordinate than run-to-failure maintenance because the maintenance schedule must be planned. Preventative maintenance is less complex to coordinate than predictive maintenance because monitoring strategies do not have to be planned nor the results interpreted. preventative maintenance minimizes the time taken for a repair reactive maintenance has many overhead costs that can be avoided by planning . Preventative maintenance for various equipment and facilities is quite nuanced. For instance, maintaining certain equipment may include a "preventative maintenance checklist" which includes small checks which can significantly extend service life. Furthermore, other considerations such as weather and equipment are taken into account; for instance, in the case of HVAC systems, maintenance is often performed before the hottest time of the year. The main purpose of planned maintenance is to avoid or mitigate the consequences of failure of equipment. This may be by preventing the failure before it actually occurs which Planned Maintenance and Condition Based Maintenance help to achieve. It is designed to preserve and restore equipment reliability by replacing worn components before they actually fail. Preventive maintenance activities include partial or complete overhauls at specified periods, oil changes, lubrication, minor adjustments, and so on. In addition, workers can record equipment deterioration so they know to replace or repair worn parts before they cause system failure. The ideal preventive maintenance program would prevent all equipment failure before it occurs
