Question: 1 / 400

Which of the following is a common sign that equipment requires maintenance?

An increase in performance

Unusual noises and vibrations

Unusual noises and vibrations are commonly recognized indicators that equipment may need maintenance. When machinery operates normally, it typically runs smoothly and quietly, with minimal vibration. If there are sudden or unexpected noises, such as grinding, clanking, or rattling, this can signify that components are wearing out, misaligned, or damaged. Similarly, increased vibration can indicate issues such as imbalance or loose parts, which can lead to further deterioration if not addressed promptly. Thus, monitoring for these signs is crucial for preventive maintenance and ensuring the longevity of the equipment. Recognizing these symptoms allows maintenance technicians to investigate and rectify the underlying problems before they escalate into more costly repairs or complete breakdowns.
