Red Seal Heavy Duty Equipment Technician Practice Exam

Ignoring strange noises from machinery can lead to an increased risk of equipment failure because unusual sounds often indicate underlying issues within the machine. These noises may suggest problems such as wear on components, misalignment, lubrication failure, or other mechanical defects that, if left unaddressed, can escalate into more significant failures. By not investigating these noises, a technician may miss crucial warning signs, resulting in severe damage to the equipment, costly repairs, unplanned downtime, and potentially hazardous situations. In contrast, improved performance, reduction in maintenance costs, and enhanced safety features are unlikely consequences of neglecting to address potential issues indicated by strange noises. Instead, the opposite is usually true; ignoring maintenance needs often leads to higher costs and reduced performance.
