Try to tighten them up till each wheel is locked by using the star wheel. Next back it off 8 to 9 clicks or teeth. You might have to go a few more till it rolls free. Most important is to adjust each axle the same side to side. If one wheel slides, tighten the other and back off the one sliding a bit. Its trial and error to get them even. They should remain that way once you get them wore in. Joe
