What should always be disconnected first during maintenance of an air compressor?

• A. The air hose
• B. The pressure gauge
• C. The power supply
• D. The oil reservoir

Answer: (C)

During maintenance of an air compressor, disconnecting the power supply should always be the first step. This ensures the safety of the personnel conducting the maintenance. By turning off and disconnecting the power, you significantly reduce the risk of accidental activation of the compressor while working on it. This precaution helps to prevent potential injuries and equipment damage that could occur if the compressor were to start unexpectedly. In the context of the other options, disconnecting components like the air hose, pressure gauge, or oil reservoir can wait until the power supply has been safely disengaged. While it is essential to be cautious with all parts of the machine, prioritizing the disconnection of the power supply is a critical safety measure in maintaining any electrically operated equipment.
