Hi, I had only recently installed a new belt and new weights in the vario, as the old ones were useless. Now, after a day, I noticed by chance that the vario lid became mega hot, so I took it down. When removing from the variomatic, I could do everything except the gliding bolts (which somehow edged) and thus logically the lid behind it (which was busy at one point, in doing so metal-pains were created) not abzi I have tried everything (Wd40 and felt two hours to move the gliding bolt with a pliers, but everything hopeless. Does anyone have an idea ? Lg (written with the cell phone)
