What should I pay attention to when using a jack?

1. Choose a level and hard ground support

First, in addition to the inflatable jack, be sure to find a flat and hard ground before using the jack. The grounding area of the jack is limited, and the soft and uneven ground can easily cause the vehicle to hit the ground. If the car is broken, it is better to hurt people.

2. Verify the maximum load capacity of the jack before use

Second, before using the jack, make sure that the load label on the jack matches the weight of the vehicle. If possible, empty the contents of the vehicle as much as possible to reduce the weight of the vehicle and prevent the overloaded jack from supporting the vehicle and smashing it. Dangerous situations occur on the ground.

3. The wheel hub screws turn in a "diagonal" order

Before supporting the car with the jack, be sure to use a wrench to loosen the screws that fix the wheel hub in a diagonal order. The first two turns of the wheel hub screws require relatively large force. If the car body shakes due to tightening, it is very dangerous to knock the car off the jack.

4. Place as much support as possible under the car

If conditions permit, try to place some support (such as a spare tire) under the car to prevent the jack from having problems and causing the car to fall. At the same time, when using the jack, be sure to pull the handbrake and put the vehicle in P (manual first gear) to prevent the vehicle from moving.
