1.断续工作压力指入口工作压力，连续工作压力指工作压差。

2.马达不应同时在压力和转速下工作。

3.推荐用68#抗磨液压油，粘度37-73cSt，清洁度ISO18/13。

4.马达在断续工作条件下，运行时间每分钟不得超过10%。

5.工作油温80°

6.马达满负荷工作前，应在工作压力的40%以下磨合1h。

7.马达允许背压10MPa，但推荐不要超过5MPa，超过时应接外泄油管。

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

4. The running time should not exceed 10% under intermittent working conditions

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
