Note: 

1. Intermittent means the entrance of 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 5MP, 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 ISO 18/13.
