What best describes preventative maintenance?

• A. Regular scheduled maintenance to prevent failures
• B. Replacing components regardless of condition
• C. Repairing equipment only after it fails
• D. Relying on operator observation only

Answer: (A)

Preventive maintenance is a proactive approach where maintenance tasks are done on a planned schedule or based on usage, with the goal of preventing equipment failures before they occur. By regularly inspecting, lubricating, adjusting, and replacing wear parts at set intervals, you reduce the chance of unexpected downtime and extend the life of components. This differs from waiting for something to break or performing replacements only after a fault is found, and it’s more reliable than relying solely on operator observations, which can miss subtle wear or degradation.
