Changing a V belt once a year on a fan drive is an example of a preventative maintenance task because it involves scheduled actions taken to prevent potential breakdowns and prolong the life of the equipment. Preventative maintenance focuses on regular, planned maintenance activities that help avoid equipment failures before they occur. By replacing the V belt at scheduled intervals, you minimize the risk of unexpected equipment failure that could occur if the belt were to snap unexpectedly due to wear and tear.

In contrast, conducting a safety inspection is more about compliance and safety than maintenance; repairing broken equipment involves reactive measures after a failure has occurred, and monitoring usage patterns of machinery can provide insights for future maintenance but does not directly constitute a maintenance task itself. Preventative maintenance is about taking proactive steps, like the periodic replacement of a V belt, to ensure equipment runs smoothly over time.
