First of all, I am very grateful to new and old customers for choosing our bumper car products. It is our affirmation to choose our powerful bumper car manufacturers as partners. Then we all know that any product is not infinitely used and will not be damaged, so is our bumper car. As a consumable, it will also be bad, so what should we do? According to previous customer feedback, some customers' bumper cars have been used for half a year or a year, and there will be a small problem. This is normal, don't panic, some minor problems can be repaired by yourself according to the instructions. What if it is other circumstances? For example, when you find that there is music in the bumper car, but you don't go, what should you do? In this case, there is a problem with the circuit board of the bumper car. Let's see if it is not connected well. Let's see if the battery is stuck in and it is tight, so that they can fully connect. If after a period of operation, it is found that the front wheel of the children's bumper car is not in the right direction, and even the steering wheel is somewhat difficult to turn, it is necessary to proofread the wire so that the steering wheel can hit the wire, in this way, the problem of the wrong direction of the front wheel can be solved. When it is found that the controller of the bumper car is broken, don't worry too much. Just touch the two wires on the coin switch directly and see if the bumper car can continue to work. If not, this indicates that the controller has been damaged, and a new controller can be replaced. If you find that the remote control switch of the bumper car can't work normally, then use your hand to move the wire to see if you can hear the sound of the tick. If you can't hear the tick, it means that the remote control switch of the battery bumper car has been damaged. It may be caused by a short circuit inside. Just replace the bumper car remote control.
