Preventative Maintenance (Pm) Definition

Preventative maintenance (Pm) is the proactive care and servicing of equipment in order to prevent future failures. Pm is often conducted on a regular schedule, such as monthly or yearly, in order to identify and correct any issues before they become major problems.

Pm is an important part of any effective maintenance program, as it can help to extend the lifespan of equipment, improve safety, and reduce downtime. In some cases, Pm may even be required by law or regulation.

There are many different types of Pm activities that can be performed, depending on the type of equipment involved. Some common examples include inspections, cleaning, lubrication, and calibration.

In order to be effective, Pm must be tailored to the specific needs of the equipment in question. A good place to start is by reviewing the manufacturer’s recommendations for Pm tasks and frequency.
