Precautions for use
1. Do not knock when installing the coupling
2. Pump casing shall be filled with oil
3. Exhaust the air in the suction pipe
4. Check the filter
5. Check the cleanness of oil
6. Check the oil level
7. Check whether the pump direction is correct
8. Connect the oil drain pipe with the highest T-port
Common troubleshooting
1. No pressure, abnormal sound in pump case		There is air in the suction pipe; Remove air from suction piping. Damage of internal accessories; Immediately stop using and contact us.
2. No pressure, no abnormal sound in the pump case		The coupling is loose; Reinstall and secure coupling. Mismatching of steering; Newly order a pump that matches the steering. The oil suction pipe switch is not turned on; Open the oil suction pipe switch. The pressure of control valve is not enough; Clockwise adjust control valve. The control valve element is blocked by impurities; Remove the valve core and clean it.
3. There is pressure, but the pressure is not enough, without abnormal sound		Insufficient pressure of control valve DR valve; Clockwise adjust DR valve. Control valve DR valve is blocked by impurities; Disassemble the valve core of DR valve and clean it.
4. There is pressure, but there is abnormal sound in the pump		The coupling is loose; Reinstall and secure coupling. Air or moisture in the oil; Remove air or filtered water from the oil suction pipe. Impurities in the pump; Immediately stop using and contact us.
5. Insufficient flow		Low oil tank level; Fill the oil to the normal level. Blockage of oil suction pipeline filter; Replace the filter. The maximum displacement limiter is limited; Anticlockwise adjust the displacement limiter.
6. Excessive noise		The coupling is loose; Reinstall and secure coupling. Air or moisture in the oil; Remove air or filtered water from the oil suction pipe. Excessively high pressure of control valve DR valve; Anticlockwise adjust DR valve.
7. Oil leakage at framework oil seal		The oil drain pipe is too long or blocked; Shorten drain piping, reduce turns, and detect blockages. Excessive wear and oil leakage of internal accessories; Immediately stop using and contact us. Too high opening pressure of check valve of oil drain pipe; Replace with lower pressure or remove check valve.
8. Fast oil temperature rise		Poor radiator effect; Replace the radiator. The overflow valve of the system is damaged or the pressure is too low, resulting in long-term large. displacement output of the pump; Replace or adjust the overflow valve pressure of the system.
