Instructions for Use and Precautions

Select the appropriate oil viscosity according to the equipment's lubrication guidelines. During use and storage, 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. Never mix this oil with other types, and never combine different categories of oils.
