Where to place car jack when changing tire?
Jack-why it is needed and how to install it
A jack is a technical device for lifting loads mainly from the bottom up. Jacks come in various types: screw, rack and pinion, hydraulic and pneumatic. Screw and hydraulic jacks have gained the greatest popularity due to their compactness.
It must be said that hydraulic jacks have an advantage over screw jacks due to the fact that they lift the car faster and lower it, and also require significantly less effort, in this regard, hydraulic jacks are used in tire fitting.
The car from the factory is equipped with a jack that meets the characteristics of a particular car, load capacity and lifting height.
The jack is necessary to lift the car and then replace the wheel. If the car is loaded, then you need to unload it before lifting it and release it from the passengers. If possible, try to position the car on a horizontal section with a hard surface, this will avoid rolling back the car when it is being jacked. Lock the wheels of a car with an automatic transmission, turn the gearbox selector to the "P" position, on cars with a manual transmission, turn on first gear and also turn on the hand or foot brake, depending on what your car is equipped with and regardless of which gearbox it has. It would not be superfluous to fix the wheels on both sides with tackles or, for example, bricks, if possible. In no case do not lift the car without locking the wheels.
Install the jack only in the places intended for this purpose so that its recess in the stop enters the edge of the threshold closer to the wheel being replaced. Special icons on the thresholds mark the places for installing the jack. If there are side linings on the car, remove them. The jack must be in a vertical position relative to the stop point in the body.If the proposed work requires the jack to be installed in a non-standard place, then it must be strong to hold the weight of the car. When installed in an improper place, when under-cranking, deformation of the threshold of the car is possible, which entails expensive repairs, therefore, carefully and responsibly treat the place of installation of the jack. Make sure of the hardness of the coating of the place on which the jack will rest, in case of wet soil or snow, try to find a piece of board to put under the base of the jack and exclude its failure. Soft ground can cause the car to fall after lifting it with a jack. Lift the car with the jack smoothly, without sudden movements. After dismantling the wheel, it can be placed under the car for safety.
