When the compressor working, the cooling system must be working at the same time. The machine must not be working without oil, so please don’t forget to put diesel oil or engine oil into the compressor before running. In addition, you must pay attention to the level of oil. When running, if the machine vibrates violently, please add pad or towel under the compressor.
