1. Before use, check whether each department is normal.
2. The rules in the main parameters should be strictly observed during use, and should not be overloaded. Otherwise, if the lifting height or lifting tonnage exceeds the specified limit, serious oil leakage will occur at the top of the fuel tank.
3, if the manual pump body of oil is insufficient, need to be added to the pump should be fully filtered N32 # hydraulic oil to work.
4, electric pump, please refer to the manual of the electric pump.
5, the weight of the center of gravity to choose moderate, reasonable choice of electric jacks focus point, the bottom should be flat, at the same time to consider the soft and hard ground conditions, whether it is necessary to line tough wood, placement is stable, so as not to subsidence or tilt load.
6. After the electric jack is lifted by heavy objects, the heavy object shall be firmly supported by the support in time, and the electric jack shall not be used as a support. If you need to support heavy loads for a long time, please use YZL self-locking jack
7. In addition to the correct placement of the EHV jacks, multiple top diverter valves should be used, and the load of each electric jack should be balanced, taking care to keep the lifting speed synchronized. It is also necessary to take into account the possibility of sagging due to the uneven weight of the ground and to prevent the risk of tilting the lifter.
8. When using, firstly connect the quick joint of the hand pump to the top, then select the position, and screw the oil drain screw on the oil pump to work. To lower the piston rod, loosen the hand pump manually counter-clockwise and the cylinder is unloaded and the piston rod is gradually lowered. Otherwise it will be dangerous to drop too fast.
9, the LH hydraulic jack hydraulic pressure, after lifting, you can quickly remove, but can not be connected to the hose to pull the LH hydraulic jack. 10, the user must not exceed the rated travel time, so as not to damage the electric jack .
11, the use of the process should avoid severe vibration jack.
12. It is not suitable for use in workplaces with acids, alkalis and corrosive gases.
13. The user shall regularly inspect and maintain the LH hydraulic jack according to the usage conditions. It is widely used in power maintenance, bridge maintenance, lifting of heavy loads, static pressure piles, foundation settlement, bridges and shipbuilding, especially in the construction of highways and railways and mechanical schools. Adjustment, equipment removal and other aspects.
