Which gauge reading should be monitored for safe operation of the generator?

Monitoring the temperature gauge is essential for the safe operation of a generator because it indicates how hot the engine and other components are running during operation. High temperatures can signify that the generator is overheating, which may lead to engine failure or damage if not addressed promptly.

Keeping an eye on the temperature reading ensures that the generator operates within its designed limits, thereby preventing potential hazards like fires or mechanical breakdowns.

While oil pressure, rev counter, and water level are also important indicators of a generator's health and functionality, temperature monitoring directly relates to safe operational limits and the risk of overheating. Ensuring the temperature remains within a safe range is crucial for the longevity and reliability of the generator.
