When conducting routine maintenance on machinery, what should you critically check?

When conducting routine maintenance on machinery, critically checking the condition and levels of all fluids is essential for several reasons. Fluid levels, such as oil, coolant, and hydraulic fluids, directly impact the performance and reliability of machinery. Insufficient levels can lead to overheating, component failure, and decreased efficiency. Additionally, checking the condition of these fluids can reveal signs of contamination or degradation, which may indicate a larger issue requiring attention. For instance, dirty oil may suggest that it’s time for an oil change or that there are internal wear issues that need addressing before they escalate.

Maintaining optimal fluid levels and quality ensures that machinery operates smoothly, reducing the likelihood of unexpected breakdowns and costly repairs. Regularly monitoring these factors is a vital part of preventive maintenance, promoting safety and longevity of the equipment.
