Instructions for Use and Precautions

According to equipment lubrication guidelines, select oil products with appropriate viscosity. During use and storage/transportation, prevent contamination by foreign objects and strictly avoid mixing in mechanical impurities or water. Ensure the oil tank remains clean—when changing the oil, thoroughly flush both the tank and oil lines—and never mix it with oils of different types.
