Question: 1 / 400

What is a typical sign that a machine may need maintenance?

Consistent operational sound

Unusual vibrations or noises

Unusual vibrations or noises are typically indicative of a machine that may need maintenance. When a machine operates within the norm, it generally produces consistent sounds and vibrations. However, any changes in these patterns, such as unexpected noises or vibrations, can signal potential mechanical issues, such as worn bearings, misalignments, or other components that are not functioning correctly. Addressing these unusual signs early can prevent further damage and costly repairs, ensuring the equipment remains reliable and efficient.

In contrast, sounds that are consistent, regular production output, and optimized energy consumption suggest that the machine is running smoothly and does not require immediate attention. These characteristics indicate that the machine is likely functioning well within its designed specifications.
