I have a new to me 8 harness Leclerc Nilus II and have finally gotten it put together. BUT the treadling is really hard - on the first two treadles I have to stand up to get the harnesses to go up at all. I may have done something wierd when we put it together. Any sugestions? Also - is anyone using the back hinge treadles with a Nilus? Wondering how it works. Looks like for another $1000 I can fix this problem, but I'd love not to invest any more.... Thaks.
