Actually Gregor, that page has the exact same diagram and exact same set of instructions as the one I mentioned to begin with. The directions are simply hopelessly poorly written and no doubt Bluthner, like evidently so many others simply copied this picture and set of directions. It is word for word identical to all other examples of this I have seen so far. The numbers that correspond to the text.... don't correspond to begin with either. Look closely at what the numbers are pointing to... and compare to the directions, you'll see what I mean Cheers RicB You can find a very good service manual on the Blüthner Homepage in different languages, i.e. in English too: http://www.bluethner.de/en/index.htm Click on Service. Unfortunately, in the English version they forgot to insert the numbers in the text that corespondend to the numbers in the picture, but in the German version the numbers are not missing. Gregor
