What should be done if the pressure gauge indicates the compressor has not shut down at normal pressure?

When the pressure gauge indicates that the compressor has not shut down at normal pressure, adjusting the pressure switch is the appropriate response. The pressure switch is responsible for regulating the operational pressure of the compressor. If it is not functioning correctly, it could lead to over-pressurization, which can damage the compressor or create a safety hazard.

By adjusting the pressure switch, you ensure that the compressor shuts off at the correct pressure setting and operates safely and efficiently. Regular maintenance and proper adjustment of equipment are critical for safe operations, especially in environments like those managed by the FDNY, where reliability and safety are paramount.

The other options do not contribute to effectively addressing the issue. Ignoring the warning could lead to severe consequences and safety risks. Selling the compressor may not be a practical solution as the problem can often be fixed. Running the compressor continually without addressing the malfunctioning pressure gauge could result in equipment failure or a hazardous situation.
