Note:
1. Intermittent means the entrance of the maximum pressure; continuous working pressure means the differential pressure.
2. Motor should not work under the highest pressure and the maximum speed.
3. The running time should not exceed 10% under intermittent working conditions
4. The Maximum working temperature is 80 ℃.
5. The maximum allowable back pressure is 10MPa, but the recommended back pressure should not exceed 5MPa.a leaking pipes is needed when exceeding.
6. one hour running time under 40% of maximum working pressure is recommended before full capacity working.
7. Recommending N68 anti-wear hydraulic oil, viscosity 37-73cSt, cleanliness ISO18/13.
