The definition of PPM maintenance is a preventative maintenance program that is designed to help keep equipment running efficiently and reduce the risk of unexpected breakdowns. PPM maintenance involves regular inspections, tests, and servicing of equipment to ensure that it is in good working order and that any potential problems are identified and addressed before they become major issues. This type of maintenance is often used in industrial settings, such as factories, where the cost of an unexpected breakdown can be extremely high. PPM maintenance is also used in other areas, such as healthcare, where the cost of an unexpected breakdown can be even more severe. PPM maintenance is an important part of any business’s maintenance strategy, as it helps to reduce the risk of unexpected breakdowns and keep equipment running efficiently.
