Attention should be paid to the use of car jack. The correct use method is very important!


Recently, a man in Zhengzhou used a jack to pad bricks for the vehicle because he was worried that the vehicle would be flooded by heavy rain. Due to the wrong use of the jack, he was crushed to death by the vehicle. This tragedy also awakened the safety awareness of the majority of vehicles. We must pay attention to the way and use safety of the jack. When using the jack, the jack is respectively supported on the metal reinforcement at the lower part of the large side of the left and right bottom of the vehicle. There will be a groove or triangular mark on the metal reinforcement. Of course, the safest way is to refer to the accompanying user manual, which will detail the correct use method of the jack and the safe support location of the vehicle.


It is worth reminding everyone that if the wrong support point is selected, the chassis will be damaged, and there will be special support points for supporting the jack at the bottom of the body. The support point of household vehicles is usually on the inner side of the side skirt, like the two fins on both sides of the chassis, about 20cm behind the front wheel and about 20cm in front of the rear wheel. This fin protrudes from the chassis steel plate and can withstand relatively large pressure compared with other places. If the jack is supported on the chassis steel plate, it may cause unnecessary damage to the chassis. In addition, it is also an incorrect operation method to support the arm and lower swing of the suspension. If the jack slips and the vehicle falls down during use, the chassis and Jack will be damaged.


Precautions for use of car jack:


1. Never start the engine when the vehicle is jacked up by the jack. If the engine is started, the vibration of the engine or the rotation of the wheels will cause the vehicle to vibrate and slide down from the jack.


2. In order to ensure the safety of various types of vehicles, there are generally fixed positions when using the jack, and the jack cannot be supported on the bumper, beam and other parts.


3. When removing and replacing the outer tire of two wheels, the inner wheel of the vehicle can be stopped on a wooden block or stone padded with an appropriate height to suspend the outer tire for replacement. Pay attention to tighten the hand brake and plug the front wheel.


4. When removing and replacing the front tire or rear inner tire, cushion the front axle and rear axle of the vehicle with stones or bricks, and dig a pit under the tire to be removed to make the tire hanging and replaceable.


Special note: the rocker arm of the car jack is a split structure, which can be rotated only after it is connected with the supporting wrench and casing. Therefore, in the process of lifting the jack, the force should be uniform, and do not use too fast or too hard
