1.     Hydraulic jack must check whether the parts are normal before using.

2.     Hydraulic jacks should be strictly in accordance with the main parameters, and should not be overloaded. Otherwise, when the lifting height or lifting tonnage exceeds the regulations, serious oil leakage will occur at the top of the cylinder.

3.     If the oil volume of the manual pump body is insufficient, it is necessary to add the fully filtered N33 hydraulic oil to the pump body.

4.     For electric pumps, please refer to the instructions for using the electric pump.

5.     The center of gravity should be moderately selected. The focus of the hydraulic jack should be properly selected. The bottom surface should be leveled. At the same time, the soft and hard conditions of the bottom surface should be considered. Whether the tough wood should be padded and placed is stable, so as not to sink or tilt the load.

6.     After the hydraulic jack lifts the heavy object, the support should be used to support the heavy object in time. It is forbidden to use the jack as a support. If you need to support heavy objects for a long time, please use a self-locking jack.

7.     If several jacks are required to be lifted at the same time, in addition to the correct placement of the hydraulic jacks, multi-top diverter valves should be used, and the load of each hydraulic jack should be balanced, keeping the lifting speed synchronized. It is also necessary to consider the possibility that the ground may be sunken due to uneven weight, and it is dangerous to prevent the weight from being tilted.

8.     Firstly, the quick joint of the manual pump is butted with the top, then the position is selected, and the oil discharging screw on the oil pump is screwed tightly. To make the piston cylinder descend, the hand wheel of the manual oil pump is slightly loosened in the counter-clockwise direction, the cylinder is unloaded, and the piston cylinder is gradually descending. Otherwise, it will be dangerous to fall too fast.

9.     The hydraulic jack is a spring reset structure. After lifting, it can be taken out quickly, but the connecting hose can not be used to pull the jack.

10.  Because the hydraulic jack lifting stroke is small, the user must not exceed the rated stroke when using, in order to avoid damage to the jack.

11.  The hydraulic jack should be protected from severe vibration during use.

12.  Not suitable for use in places where there are acids and bases and corrosive gases.

13.  Users should check and maintain regularly according to the usage.
