One of the P22's I serviced at Syracuse University fell over on an instructor and broke his ankle. He also grabbed it at the top and pulled to the rear and bingo! However it was not all his fault. Careful inspection showed a screw holding the caster plate to the frame of the piano had worked loose and prevented the caster from rotating. Even though the piano was on carpeting, this was a major factor. After that, we upended every vertical in the building and found others starting to do the same. With students already moving pianos around, rippling carpet and high door sills, we don't need more hazards..... Mike Kurta Chicago chapter
