How frequently should the oil level of self-lubricated air compressors be checked?

The correct answer indicates that the oil level of self-lubricated air compressors should be checked daily. Regular daily inspections are critical for maintaining optimal performance and longevity of the compressor. Air compressors rely on proper lubrication to function efficiently; insufficient oil levels can lead to increased friction, overheating, and potential failures. By checking the oil level every day, technicians can ensure that the compressor is operating within its designed parameters, helping to prevent breakdowns, reduce wear on internal components, and improve overall reliability. This frequent monitoring is especially important in heavy-duty applications, like those often found in school buses, where equipment must perform consistently under various operating conditions.
