1. First, prepare No. 32 or No. 46 anti-wear hydraulic oil (depending on the temperature and region), and after preparing the hydraulic oil, you can start to fill the oil cylinder of the hydraulic wrench pump station with oil (pay attention to remind the oil inlet hole of the electric pump, The position of the oil outlet, the level gauge and the pressure regulating valve), pay attention to the level gauge when filling oil, when the level gauge shows 3/4, you can stop pouring oil. Note: If the oil is not new, then it needs to be filtered with a filter screen to prevent debris or impurities from entering the oil cylinder; the thermometer in the liquid level gauge is an oil temperature gauge; the anti-wear hydraulic oil in the oil cylinder is best if used frequently 1- Change it every 2 weeks, or every 1-2 months if you don't use it frequently.
2. The next step is the hydraulic wrench oil pipe. When connecting the oil pipe, pay attention to the connection of the quick connector must be tightly locked and locked, and there must be no gap after locking. Only in this way can the connection be ensured, so that the check valve in the joint is opened and the oil circuit is unblocked. Otherwise, after the connection, the steel balls in the joint will not meet, and the one-way valve in the joint cannot be opened, resulting in the blockage of the oil circuit, the joint will be full of pressure, and the wrench will not be able to operate. The second is to avoid excessive bending of the oil pipe when connecting the pump station, the oil pipe and the wrench, and use it as straight as possible.
3. Connect the hydraulic wrench pump station to the 220V power supply, check the tightness of the pressure regulating valve before turning on the pump station switch, and loosen the pressure regulating valve to avoid starting with pressure. The red key on the remote control handle of the pump station is the power-off key, and the green key is the power-on and oil-in key. When a new pump station or a pump station after oil change is started, it is necessary to switch the motor on and off 3-4 times and idle for a period of time to remove the air in the fuel tank. Then turn on the switch, press and hold the oil input button, and slowly and uniformly tighten the pressure regulating valve to the required pressure (MPa). After adjusting the pressure, you can start to use the wrench.
4. Before use, determine whether the bolts are tightened or disassembled, and change the direction of the drive shaft according to the needs of the site. Press and hold the circular button in the middle of the locker and pull the drive shaft lightly to disengage the drive shaft from the locker, and the drive shaft can be pulled out. After confirming the direction, put the drive shaft out of the wrench, make it fully engage with the spline sleeve, and then tighten the lock.
5. When using the hydraulic wrench, press and hold the oil input button, the oil pipe will start to enter the oil, and the drive shaft will start to rotate. When you hear the sound of the wrench clicking, it proves that the oil input is completed and then release the oil input button, and the wrench will start to return. After a period of time, the sound of the wrench clicking proves that the oil return is complete. (Note: Be sure to press the oil input button to start oil feeding after the oil return is completed, if the oil return is not successful.)
6. The square shaft starts to rotate, the wrench stops rotating in place, the pressure gauge rises rapidly from "0" to the set pressure; release the button, the wrench automatically returns, repeat several times, make the wrench idling for several times, observe the wrench's rotation, To determine whether to loosen or lock the operation, only put the wrench on the socket when there is no abnormality.
