The jack is generally under the cushion of the trunk, and it has 3 types: mechanical jack, hydraulic jack, and pneumaticjack. A general car jack is mechanical, has strong reliability, low cost, long life, and small volume, but is relatively laborious.
Note before using the jack:
1. Park the car on a hard and smooth road surface and fix it. If the CAR IS IN LOOSE GROUND CANNOT FIX JACK CAN BE IN THE AREA ON jack MAT BELOW BIG, HARD, SMOOTH OBJECT. Such as wood boards, floor tiles , and so on.
2. Turn off the car and hang the gear. The car with automatic transmission is in P gear and put on the handbrake. Manual gear the car to hang a block or hang reverse gear, and pull the handbrake. Because the handbrake can only provide brake force to the rear wheel, after hanging gear can be through the engine brake, even if there is a wheel off the ground, the other three wheels also have braking force.
3. Safety warning signs must be placed behind the vehicle. Place the warning triangle at a safe distance behind the car and pay attention to the maximum bearing capacity of the jack. The label on the jack indicates the maximum bearing mass of the jack, and the jack is best for special use. Mind that there are no people in the car!
How should the jack be used?
1. Align with the support point of the vehicle chassis. Before lifting to find the support point of the vehicle position, the support point of the family car is usually in the side skirt inside, in the back of the front wheel 20 centimeters or so, in front of the rear wheel 20 centimeters or so. Some vehicles have raised points and some have sunken points. Never prop the jack on the steel plate of the chassis! To avoid unnecessary damage to the chassis.
2. Lifting operation skills. After determining the position, use your hands to twist the knob on the jack to raise the jack and slowly clamp it to the position of the support point. Then use the connecting rod tool. Lift operation should be steady and slow.
3. Do not drill under the car. Do not get under the car after the vehicle is raised, which is also a warning on the jack. Because the jack is only for temporary emergency use, its stability and repair shoplifters can not be compared!
4. It's safer to put a spare tire under the car! Put the spare tire under the car before changing it. In case the jack fails, the car falls off with a spare tire.
