The jack must be placed on the hard flat road, in the application of the jack must be supported on the special type of support point, support point by thick steel plate manufacturing compressive strength is relatively large. It is usually used to lift by hand. The strength must be symmetrical and not too fast and too fierce.

Before repairing the car, the first thing to do is to fix the car, in order to prevent the car hydraulic jack in the process of lifting the car deviation to harm the car and people. Fixed fixed car handbrake application is far from enough, the most appropriate way is to pull the hand brake at the same time will be manual block car hanging into 1 gear or reverse gear, automatic gear car pull the handbrake drag to P block can be.

The jack must be placed on the hard flat road surface, if nature makes the car broken in the soft road surface or stone, you can apply the material solid wood board point under the jack to ensure that the support perspective of the jack, different natural environment is different, but we must ensure that the jack is appropriate. In addition, the spare tire can be placed on the car chassis, if the jack died tragically also have spare tire can be bottom.

Each side of the side skirt is parallel with the side skirt of the jack support point, the hand can touch, then in the application of the jack must be supported on the special type of support point, support point by thick steel plate manufacturing compressive strength is relatively large. Rack jack other positions like the engine under the guard plate, the swing arm of the suspension need to prevent the support of the jack, because its own compressive strength is low, it is easy to lead to unnecessary damage when running. The application of the jack is usually the use of hand lifting, in the use of the strength must be symmetrical, not too fast too fierce.
