Hello Philippe Rouille, a very good idea to give an advice like that.

You might expand it with following experience for smaller movements:

-- NEVER WIND UP A MUSIC BOX WHILE IT IS PLAYING: The cylinder might
go back a little bit and ruin teeth, dampers or pins.  Let the music box
play until the end of the tune.

-- BLOCK THE SPEED REGULATOR FOR SENDING / MOVING: You should block
the speed regulator with a little piece of paper, if you will be
transporting it over long distances.

Now and again people ask me: How To Care For A Music Box.  You have given
the answer.  Do you agree, if I make a translation into German?
