Management of other oils 

Other oils used include engine oil, hydraulic oil, gear oil, etc.; different grades and grades of oils cannot be mixed; different varieties of excavator oils have different chemical or physical additives added during the production process; to ensure that the oil is clean and prevent debris (water, dust, particles, etc.) from being mixed in; choose the oil label according to the ambient temperature and use. If the ambient temperature is high, the oil with high viscosity should be selected, and if the ambient temperature is low, the oil with low viscosity should be selected. The viscosity of gear oil is relatively large to adapt to larger transmission loads, and the viscosity of hydraulic oil is relatively small to reduce the resistance of liquid flow.
