Piano Regulation Caution - Yamaha Silent Piano SG Series Maintenance Handbook

3. Piano regulation caution

1) Removing the Lower Front Board
The switch box obstructs removal of the lower
front board. Use the procedure shown on the
right and remove the switch box before removing
(opening) the lower front board.
1) Disconnect the three lines on the rear of the
switch box.
2) Loosen the three attachment screws, and then
slide the switch box forward to remove.
2) When Tuning
Since the shank stopper impedes use of the
wood mute when tuning the treble strings, the
TX600250 mute is specially designed for this
purpose and offers easy use.

*When removing the keyboards, be careful not to touch
the key shutter.
Key shutter:
Remove the key shutter from the keyboard. Pull the key
shutter while slightly slanting it.
* When inserting the key shutter, also slant and insert it.

attach the damper pedal rod.
