The precaution of using the trailer jack

1.Never start the engine when the vehicle is jacked up by the jack, because the vibration of the engine or the rotation of the wheels will cause the vehicle to slide down from the jack, causing danger.
2.In order to ensure the safety of various types of vehicles, there are generally fixed positions when using the jack, and the jack cannot be supported on the bumper, beam and other parts.
3.Maintenance personnel must not work under the vehicle without support. Passengers cannot stay on the vehicle when changing wheels, because their movement may cause the vehicle to slide off the jack.
4.If there is no jack when changing the tire, different emergency measures can be taken according to the different positions of removing and changing the tire.
5.When removing and replacing the outer tire of two wheels, the inner wheel of the vehicle can be stopped on a wooden block or stone padded with an appropriate height to suspend the outer tire for replacement. Pay attention to tighten the hand brake and plug the front wheel.
6.When removing and replacing the front tire or rear inner tire, cushion the front axle and rear axle of the vehicle with stones or bricks, and dig a pit under the tire to be removed to make the tire hanging and replaceable.
