Vehicles often use jacks during self-maintenance, such as changing tires. There are several points to consider when using jacks.
1. Use location. In order to ensure the safe use of jacks, they generally have a fixed position. Jacks cannot be used to support bumpers, beams and other parts.
2. Timing of use. When the vehicle is jacked up by the jack, never start the engine, because the vibration of the engine or the rotation of the wheels will cause the vehicle to slip off the jack and cause danger.
3. Other points of attention: automobile maintenance personnel must not work under unsupported vehicles. Passengers should not stay in the vehicle when changing tires, because their movement may cause the vehicle to slip off the jack. If there is no jack when changing the tires, different emergency measures can be taken according to the different positions of the tires.
4. Replaceable: When replacing the outer tires of the two wheels, the inner wheel of the car can be parked on a wooden block or stone with a proper height, and the outer tire can be replaced in the air. Pay attention to tighten the hand brake and plug the front wheel. When replacing the front tires or rear inner tires, use stones or bricks to stabilize the front axle and rear axle of the car, and dig holes under the tires to be removed so that the tires can be replaced in the air.
