Precautions for using common auto repair tools

Car jack, as the single tool with the highest frequency of use, remember to fix the vehicle well when using it, so as to avoid the unstable fall of the car after lifting. As long as such accidents occur, it is a serious operation accident. When we use a jack, we must first check the maximum weighing capacity of the jack, do not exceed it, then find the support point of the vehicle chassis, do not support other positions at will, and finally pay attention to the ground conditions, and try to choose a ground suitable for the jack to operate. If the car is on a soft ground, a large and hard support must be placed under the jack.
