1. Air compressor lubricating oil, generally speaking, is of high oil quality and contains oxidizing agents, which are not easily oxidized or deteriorated, not easy to foam, and have a low residual carbon content and high flash point. Due to its wide variety, the commonly used ones are:

　　A 13 "compressor oil (winter oil)

　　B 19 "compressor oil (summer oil)

　　2. Please keep the oil level within the red circle in the middle of the oil mirror. Adding too much oil wastes lubricating oil and can easily cause carbon buildup in the air valve. Adding too little oil often leads to poor lubrication, resulting in burning or wear Therefore, the oil level should be kept within the red circle range at all times

　　3. When the oil color turns black or there is oil contamination (approximately every 500 hours of use), please change the oil once

　　4. When changing the oil, please unscrew the oil drain plug under the crankcase first, and use cardboard or other objects to remove the dirty oil. After the oil is completely drained, tighten the oil plug (apply universal glue or anti leakage paste on the oil plug teeth to prevent oil leakage), and then open the oil cap to add new oil to the middle of the red circle on the oil mirror

　　5. Do not add new oil during operation

　　6. Avoid using concentrated lubricating oil and other miscellaneous waste oils
