•about the problem of the four wheels of the skateboard landing at different times (generally, the new board is prone to problems, and it will disappear naturally after one or two weeks). Adjustment method: loosen the screw of the main bridge with the debugging tool, rotate the shock absorber to a proper angle, and then tighten the screw (it may need to be debugged for many times, In order to achieve satisfactory results)
•about the problem that the skateboard does not move in a straight line (the reason is the same as above), the debugging method is the same as above. Sometimes when you step on the slide, you will walk in a straight line. The slide plate slides slowly, one wheel turns slower than other wheels, or there is abnormal noise, generally because the bridge end nut is too tight. Adjustment method: properly loosen the bridge end nut. Pay attention not to screw too loose, in order to prevent falling off in the process of sliding, causing accidents.
•The problem of abnormal sound of sliding plate in the process of sliding (such problems rarely occur) is too tight. It is also possible that the nut at the end of the main bridge is too loose. Adjustment method: carefully find out the cause and properly adjust the nut tightness. As for the problem of inflexible turning of sliding plate, it is generally due to the too tight nut at the bridge end. Adjustment method: properly adjust the nut tightness.
