Generally, the jacks equipped with the vehicle meet the specifications and can be used directly.

However, if the jack is equipped by itself, it should be noted that the tonnage of the vehicle must be within the bearing range of the jack to avoid overload.

The ground contacted by the jack must be horizontal and hard, because after the vehicle is jacked up, all the weight is pressed on the jack. If the ground is soft, it will sink and cause the vehicle to lose its center of gravity.
