1,All parts must be checked before use.

2,When using the main parameters should strictly comply with the provisions, avoid ultra high overload, or when the lifting height or lifting tonnage exceeds the provisions, the top of the cylinder will occur serious oil leakage.

3If the amount of oil in the manual pump body is insufficient, it shall be added to the pump after sufficient filtrationN33 #The hydraulic fluid works.

4Please refer to the operation manual of electric pump.

5, the weight center of gravity to choose moderate, reasonable choice of jack's point of impact, the bottom surface to pad, at the same time to consider the soft and hard conditions of the ground, whether to pad tough wood, placed smoothly, so as not to sag or tilt.

6, after the jack will lift the weight, should promptly use the support to support the weight firmly, prohibit the use of the jack as a support. If you need to support heavy objects for a long time, please choose.

7If several jacks are needed to lift at the same time, in addition to the correct placement of jacks, multiple shunt valves should be used, and the load of each jack should be balanced, pay attention to keep the lifting speed synchronized. It is also necessary to consider the possibility of ground subsidence due to uneven weight to prevent the risk of tilting caused by lifting.

8When in use, first connect the quick joint of the manual pump with the top, then select the right position, tighten the oil release screw on the oil pump, then it can work. To make the piston rod drop, the hand wheel of the manual oil pump is slightly loosened in the counterclockwise direction, the cylinder is unloaded, and the piston rod drops gradually. Otherwise it will be dangerous to fall too fast.

9, separated type jack system spring return structure, after lifting, can be quickly taken out, but can not be connected with the hose to pull the jack.

10, because the jack lifting travel is small.Users must not exceed the rated travel.To avoid damaging the jack.

11, the use of the jack should avoid violent vibration.

12It is not suitable to use in the workplace with acid, alkali and corrosive gases.

13Users should check and maintain regularly according to the usage
