    Bruce,
    Thanks for your explanation.
    I thought of some adjustment which could decrease
    this shaking.
    There is a misterious screw on the "other side" of
    the Trommel, (the side of the legs) of very small size,
    when they adjusted in Freiberger factory, they mainly rotated
    this screw. My German is too poor to understand their explanations
    but somehow I concluded from their explanation that they were
    adjusting the backlash. The standard package for SNO
    contains a "watchmaker screwdriver", and the only possible use
    of it can be adjustment of this screw (all other screws are
    of much larger size). On the other hand, the user manual says
    that "it is prohibited to rotate this screw on board of a ship",
    and that this has to be done only in special workshops.
    Do you understand what this screw really does?
    
    Alex.
