Can't really help you here.

This is not the answere for your question but if you want to stick with
stygmorgan you could just do a quick google translation of the manual.
Spanish->German (you seemed to be german by the .de in your email)
Not the best translation but probably good enough to start with. A year ago I
worked my way through a site in japanese about guitar repair and it was
understandable, although not perfect.
