What kind of maintenance does preventative maintenance involve?

Preventative maintenance is a proactive approach designed to keep systems and machinery in good working order by conducting regular inspections and performing minor repairs. This type of maintenance aims to identify and address potential issues before they lead to more severe problems or failures. By implementing routine checks and minor adjustments, the lifespan of the equipment can be extended, and unplanned downtime can be significantly reduced. This method is essential in maintaining optimal performance within collections systems, ensuring they function efficiently and effectively over time.

The other options highlight approaches that do not align with the concept of preventative maintenance. Reactive responses to failures, annual deep cleanings alone, or a blanket upgrade of all components do not incorporate the systematic and scheduled nature of preventative maintenance, which focuses on maintaining equipment through regular care rather than only addressing issues as they arise or through sporadic intensive efforts.
