A car jack is a device used to lift a car for changing tires, repairing the underside of the car, or cleaning the underside. However, improper use may result in vehicle damage or personal injury. Therefore, when using a car jack, we should strictly follow the following steps.
The first step is to place the car on a flat surface and tighten the handbrake to activate the emergency brake. Then, according to the structure of the car body, find a suitable position for the jack support, and clean up the debris under the car to prevent the jack from sliding or overturning.
Step 2. Place the car jack on a suitable support point under the vehicle. Note that the jack must be perpendicular to the ground and not tilted, and ensure that the support force of the jack is greater than or equal to the weight of the vehicle.
Step 3: Slowly rotate the handle of the jack so that the lifting plate of the jack gradually contacts the bottom of the sedan. When reaching a certain height, check the balance of the jack to prevent shaking.
The fourth step is to replace or repair car parts as needed. When changing tires, we need to use a truck crane to lift the wheels. When replacing a tire, we need to use a wrench to loosen and tighten the lug nut. Once all tasks are completed, use the reverse sequence to lower the wheels to the ground and remove the car jack from the bottom of the car.
It should be noted that we need to be alert and careful at all times when using a car jack. If we find that the stability of the jack is insufficient or there are safety hazards, we should stop using it immediately. When using a car jack, we need to be careful and put safety first to make our cars safer and more reliable.
