    * Intermittent means the entrance of the maximum pressure;continuous working pressure means the differential pressure.
    * Motor should not work under the highest pressure and the maximum speed.
    * The running time should not exceed 10% under interoittent working conditions.
    * The maximum working temperature is 80°.
    * The maximum allowable back pressure is 10MPa,but the recommended back pressure should not exceed 5MPa.a leaking pipes is needed when exceeding.
    * One hour running time under 40% of maximum working pressure is recommended before full capacity working.
    * Recommending N68 anti-wear hydraulic oil,viscosity37-73cSt,cleanliness IS018/13.
