What type of maintenance involves actions performed to increase equipment lifespan and function?

Preventive maintenance is designed specifically to enhance equipment lifespan and functionality. This type of maintenance involves regularly scheduled inspections, servicing, and minor repairs performed even when the equipment is functioning properly. The purpose is to prevent unexpected failures and downtime by addressing wear and tear before it leads to equipment breakdown. Common examples include changing oil in engines, replacing filters, and conducting routine inspections.

This proactive approach ensures that equipment operates efficiently, reduces the risk of sudden failures, and ultimately minimizes long-term maintenance costs, making it essential for any effective maintenance strategy. In contrast to other maintenance types, such as corrective or reactive maintenance—which focus on addressing issues after they arise—preventive maintenance is aimed at avoiding problems in the first place.
