What must be checked if overheating of the air compressor is discovered?

When overheating of an air compressor is discovered, checking the water cooling mechanism is critical because it is responsible for maintaining the compressor's operating temperature. If the cooling system is not functioning properly—due to blockages, low coolant levels, or failure of components such as pumps or radiators—it can lead to inefficient heat dissipation and can cause the compressor to overheat. Monitoring the effectiveness of the cooling mechanism is essential for the safe and efficient operation of the compressor, ensuring it remains within its designed temperature range to prevent damage or failure.

In addition to this, while checking the oil level, air quality, and electrical connections are important aspects of regular maintenance, they are not the immediate concern when addressing overheating. Oil levels are primarily for lubrication and can affect performance but are not the primary control for heat dissipation. Similarly, air quality affects the compressor's function and longevity, but it does not resolve immediate thermal issues. Electrical connections are vital for operation but are less directly related to cooling issues compared to the water cooling mechanism. Therefore, focusing on the cooling system is the most logical first step when addressing overheating problems in an air compressor.
