The ordinary carrying type body of the scooter, will be on both sides of the convex thin edge, do not think that this layer of thin steel plate has no bearing capacity, in fact, this area is strengthened by the system. In this position to find the reserved groove area, most of the vehicles equipped with the diamond jack at the top of the reserved groove, and this groove is used to bite the steel sheet, after the jack to align and lift the vehicle after the bite.
Before using the jack, we must let all the people on the car off, or the jack up someone in the car may shake, so it will lead to the jack can not hold, there will be the rolleover. Also, we must park the car on this level road, and on cement, not on the lawn, where the jack will not support.
