Surprisingly, the keyboard part is not rigid: it's required to handle it with the keys vertical

I experimented an "Oh sh*t" moment when a key dropped...

there is another the tricky part: it's really sticky

use an Xacto knife, a screwdriver and be patient

Remove the dust with a hoover

When reinstall the keyboard assembly, tighten the screws marked [44] and the screws marked [42] in the right order. see manuel p12

Conclusion

  • take time to read the manuel instructions
  • I had some scarry moments
  • don't do this alone ;-)

And frankly, my piano wasn't probably too noisy before, because I haven't got any sigificant improvement... Ha ha
