There is a groove on the car chassis for installing the jack. Different models are equipped with different jacks according to different weights, so jacks cannot be mixed.
When the vehicle is jacked up by the jack, do not start the engine, because the vibration of the engine or the rotation of the wheels will make the vehicle slide off the jack, causing danger.
In order to ensure the safety of all kinds of cars, jacks are generally used in fixed positions and cannot be supported on bumpers, beams and other parts. Maintenance personnel are not allowed to work under an unsupported vehicle, and passengers are not allowed to stay in the vehicle when changing wheels, because their movement may cause the vehicle to slip off the jack.
Precautions for using jack:
1. Repair the hand brake.
2. The warning triangle shall be placed at a safe distance behind the vehicle.
3. Choose a solid and flat ground and use a jack. When the car is on the soft ground, large and hard floor tiles and iron plates are placed under the jack.
4. Before using the jack, know the maximum bearing capacity and working limit of the jack.
