Points for attention in the use of jacks

A jack is often used when a vehicle repairs itself, such as changing a tire.

There are several points to consider when using jacks.

1. Use location.In order to ensure the safety of the use of a jack, there is generally a fixed position, can not be used to support the lifting jack in the bumper, beam and other parts.

2.Use time.When the vehicle is jacked up, it must not start the engine, because the vibration of the engine or the rotation of the wheels will cause the vehicle to slide down from the jack, which is dangerous.

3.Other points of note: car maintenance personnel must not work under the vehicle without support, tire replacement, passengers can not stay in the car, because their movement may cause the vehicle to slide down from the mechanical jack.If there is no jack when the tire is changed, different emergency measures can be taken according to the position of the tire.

4.Replaceable: when the outer tire of the two wheels is removed, the inner wheel of the car can be parked on the block or stone with the appropriate height, so that the outer tire is suspended for replacement.Be careful to tighten the hand brake and plug in the front wheel.When dismantling the front tire or the rear tire, use a stone or brick to stabilize the front axle and the rear axle of the car, dig a pit under the tire to be dismantled, so that the tire is suspended and replaceable.
