Stahl crossfold rollers setting

Hi.
i have just had the first set of crossfold rollers removed and reconditioned then replaced, was done by a local engineering company not a dedicated folder engineer so I am having to reset the roller pressures. I am having trouble doing this, I can get the rollers to fold but they are slipping as the pressure is to loose. The trouble is as soon as I tighten the rollers to avoid slipping the knife hits them as I manually wind it through a cycle. I have tried realignment of the knife but can only get it to complete a cycle by having the rollers too loose. Any advice please tia
