Before use, you must check whether each part is normal; when using, you should strictly abide by the provisions in the main parameters, and avoid super high and overload, otherwise, when the lifting height or lifting tonnage exceeds the regulations, serious oil leakage will occur at the top of the cylinder; such as manual pump body When the amount of oil is insufficient, you need to add N33# hydraulic oil that should be fully filtered to the pump before it can work; electric pumps please refer to the operation manual of the electric pump; the center of gravity of the weight should be moderate, and the jack's focus point should be selected reasonably, the bottom surface It should be leveled, and the soft and hard conditions of the ground should be considered, whether it should be lined with tough wood, and whether it is placed stably to prevent the load from sinking or tilting; after the jack lifts the heavy object, the support should be used to support the heavy object in time. It is forbidden to use jacks as supports. If you need to support heavy objects for a long time, please choose; if you need to lift several jacks at the same time, in addition to placing the jacks correctly, you should use a multi-jack diverter valve, and the load of each jack should be balanced, and pay attention to keeping the lifting speed synchronized. It is also necessary to consider the possible sinking of the ground due to uneven weight to prevent the weight being lifted from tilting and causing danger; when using, first connect the quick connector of the hand pump with the top, and then select the position and tighten the oil drain screw on the oil pump To work. To lower the piston rod, loosen the hand wheel of the manual oil pump slightly in a counterclockwise direction, unload the oil cylinder, and the piston rod will gradually descend. Otherwise, the descent speed is too fast will cause danger; the separated jack has a spring return structure, after the lifting is completed, it can be quickly taken out, but the connected hose can not be used to pull the jack; because the jack has a small lifting stroke, the user can use it Do not exceed the rated stroke to avoid damage to the jack; avoid violent vibration of the jack during use; not suitable for use in workplaces with acid, alkali and corrosive gas; users should check and maintain regularly according to the use situation!
