Accessing the Keyboard on Clavinova PF (P-100)

I needed to clean up an aging keyboard, to remove accumulated hair and "stuff" from the keyboard. This digital piano has a metal cover below and in front of the keys that can be removed, but there's a trick to make it easier.
Yamaha, being very good design engineers, have to attachment mechanisms: A "pinch" arrangement that clamps the keyboard to the particle board base, and five self-tapping screws. The "pinch" arrangement consists of three screws. If you look carefully, the three machine screws are on a line closer to the front of the keyboard, and the self-tapping screws are above 1/4" further back.
Remove all five of the self-tapping screws.
LOOSEN the three machine screws (turn them counterclockwise not more than two turns). That allows the metal cover to come cleanly off, and leaves the machine screws threaded in the sheet metal, so it's easier to reinstall.
After you're done, reinstall the sheet metal, rescrew the five self-tapping screws, and finally TIGHTEN the three machine screws to "pinch" the cover to the particle board.
