Yamaha b1-Silent Руководство по техническому обслуживанию

Caution:When Tuning

Since the shank stopper impedes use of the
wood mute when tuning the treble strings, the
TX600520 STICK MUTE UP PP is specially
designed for this purpose and offers easy use.

Attaching/Removing the Action

Before removing the action, remove
the shank stopper drive cables.
Follow the procedure described on the
right. (Reverse the order of the
procedure to install the action.)
Use the TX645600 lifting rod setter to attach the damper pedal rod.
