Preventive maintenance emphasizes the importance of regular checks and servicing of equipment to prevent unexpected failures and prolong its lifespan. The rationale behind checking equipment when workloads are low is tied to the objective of minimizing disruptions to operations. Conducting maintenance during lower workload periods allows for thorough inspections and necessary repairs without interfering with productivity. This approach also helps ensure that equipment remains in optimal working condition, reducing the likelihood of breakdowns when demand is higher.

The other options suggest approaches that may not effectively align with the principles of preventive maintenance. Checking equipment during high workloads could lead to operational interruptions, while performing checks only when convenient may neglect the regularity that preventive maintenance requires. Additionally, while checks can technically be performed at any time, having specific times for maintenance that align with operational efficiency is crucial for a proactive maintenance strategy.
