Predictive maintenance focuses on anticipating equipment failures before they occur through condition-based monitoring and data analysis. Monitoring with vibration equipment is a quintessential example of this approach, as it involves continuously assessing the condition of machinery to identify abnormalities that may indicate impending issues, such as imbalance, misalignment, or bearing faults. By analyzing vibration data, maintenance professionals can predict when a part may fail and schedule necessary interventions at the optimal time, reducing unnecessary downtime and maintenance costs.

The other options represent more reactive or routine maintenance tasks. Changing machine oil is a form of preventive maintenance, as it is performed on a set schedule regardless of the machine's current condition. Cleaning air filters is also a preventive task aimed at ensuring the equipment operates efficiently. Replacing worn-out parts is a corrective maintenance action taken after a component has already failed or is deemed unreliable. Thus, these tasks do not embody the predictive approach that focuses on forecasting failures based on real-time data analysis.
