Kawai GS-50

[John Ross]

Hi Ron,
Let-Off quoted from Kawai manual.
Let-off should be regulated so that, on a soft blow, the hammer releases as
close to the strings as possible without blocking. Let-off should be 3mm +/- in
the bass and 2mm +/-
in the treble.
NOTE: Make sure there is some drop to ensure the possibility of let-off.
Hammer Drop
With the action on a bench, shim the balance rail or front rail to give the
exact key dip as found in the piano. Regulate each hammer so the drop screw
touches the top of the rep. lever at the same time the jack touches the reg.
button. This is felt as a solid bump in the key. Checkthat all hammers are
level in the drop position.
NOTE:     Inncorrect setting of the drop can result in bubbling hammers when
played softly.
White key dip = 10.5mm +/-
Hope this helps.
