Erratic motion is a clear indication of intermittent mechanical failure because it signifies that a machine or component is not functioning consistently. In cases of mechanical issues, components may occasionally respond correctly but will often display unexpected behaviors such as jerking, varying speed, or incomplete cycles. This inconsistency can be attributed to problems such as wear and tear, misalignment, or issues with lubrication. These symptoms not only indicate that the equipment is failing but also suggest that it may be prone to intermittent faults that can complicate diagnostics and repairs. By recognizing erratic motion as a sign of failure, maintenance technicians can take proactive steps to investigate and address the underlying issues before they lead to complete breakdowns or more serious failures.

While loud noises and unexpected shutdowns can also indicate mechanical failure, they may not necessarily signify intermittent issues, as they can happen during consistent operation or indicate a total failure rather than an inconsistent one. Consistent performance, on the other hand, reflects that the machine is functioning properly without any signs of intermittent failure.
