Which of the following is not part of routine preventive maintenance?

Preventive maintenance is a proactive approach aimed at maintaining equipment and machinery in good working condition, thereby minimizing the likelihood of unexpected breakdowns or failures. It involves various tasks designed to prevent potential issues before they occur.

Ignoring minor repairs is not considered a part of routine preventive maintenance because preventive maintenance focuses on addressing potential problems before they escalate. When minor repairs are overlooked, they can lead to more significant issues down the line, resulting in costly repairs and downtime. Proper preventive maintenance includes tasks such as changing engine oil, inspecting belts and hoses, and cleaning spark plugs—all aimed at keeping the equipment running efficiently and safely. Therefore, the act of ignoring repairs runs counter to the purpose of preventive maintenance, which is to address and rectify any issues, no matter how small they may seem.
