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. Recommending N68 anti-wear hydraulic oil, viscosity 37-73cSt, cleanliness ISO18/13.

5. The maximum working temperature is 80℃.

6. One hour running time under 40% of maximum working pressure is recommended before full capacity working.

7. The maximum allowable back pressure is 10MPa, but the recommended back pressure should not exceed 5MPa, a leaking pipes is needed when exceeding.
