What should be noted when using a car jack?

Personal precautions:

When operating a car jack we need to wear professional safety protective equipment, such as safety helmets, work clothes, and safety shoes. We also need to conduct a safety check of the surrounding environment to ensure the safety of the site and avoid safety accidents caused by an unsafe environment. At the same time, we need to select an appropriate jack based on the weight of the vehicle and the height of the chassis. If the vehicle is too heavy or the chassis is too high, a jack with a larger tonnage should be used.

Selection of support points:

When using a car jack, we must use it carefully. First, we need to choose the correct support point. Incorrect selection of the support point can cause damage to the chassis. The bottom of the vehicle is specially designed with specific support points for the jack, usually located on the inner side of the side skirt of the family car. These areas resemble fins on both sides of the chassis and protrude from the chassis steel plate, capable of withstanding large pressure. If the jack is placed directly on the chassis steel plate, it may cause unnecessary damage to the chassis. It is also unsafe to place the jack on the suspension arm or lower crossbar. This may cause the jack to slip during use, leading to the risk of the vehicle falling and further damaging the chassis and the jack. Therefore, when using an automotive jack, we need to confirm the correct position of the support point and use it safely and without damage according to the operation guide to lift the vehicle.

Precautions during use:

During the process of lifting the vehicle with the car jack, the engine should be turned off. Once the engine is started, its vibration or the rotation of the wheels may cause the vehicle to slide off the jack, resulting in danger. If it is necessary to replace the front or rear inner tires, stones or bricks can be placed firmly under the front axle and rear axle of the vehicle, and a pit can be dug under the tire to be replaced to make it suspended. When using the jack, keep your body parallel to the vehicle to avoid being crushed by the vehicle and ensure a stable center of gravity to prevent falling. At the same time, pay attention that when lifting the jack, apply force evenly to avoid rapid or excessive operation to ensure safe and error-free lifting of the vehicle. After lowering the vehicle, check the chassis for any damage and ensure that no foreign objects are left behind.
