What is one important check an operator must perform before starting up a compressor?

Checking oil levels before starting up a compressor is crucial for several reasons. Oil serves as a lubricant for the moving parts within the compressor, helping to reduce friction and wear. Insufficient oil can lead to overheating, increased wear on components, and ultimately, compressor failure. Ensuring that the oil levels are adequate helps to maintain operational efficiency and extends the lifespan of the equipment. Additionally, a compressor that is properly lubricated can operate more smoothly, reducing the risk of unexpected breakdowns and maintenance issues.

While checking refrigerant levels, electrical connections, and temperature settings are also important maintenance tasks, they do not address the immediate operational need of ensuring that the compressor can run smoothly without risking internal damage from insufficient lubrication.
