. Use hydraulic oil for 65A C,kinematic viscosity for 15~ 50 mm2/s,the diameter of the impurity is not more than 137 I m and high quality mineral oil with a certain rust resistance, recommend 32 # hydraulic oil in winter, 46 # hydraulic oil in summer, when it is used in special environment, please consider to use other types of oil .
