greater than the figures 1n the above paragrarh.
This allows about l/32
n
after-touch or movement of the
key after the hammer lets off. The let-off is adjusted by t�e
regulating screw as sho-wn in Figures 700-I and
700-J.
NarE: The let-off screwdriver used for regulation is
equivalent to item No. 4102 (Fage 23) in Schaff Piano
Suppiies Catalog.
If the screw is turned clockwise too far
r
it will cause
the hammer to let off too soon and the piano will net function
properly with a light touch
o
Also, excessive after-touch will
occuro If the screw is b.irned counter--clockwise too far
17
the
hammer will not let off and will block against the reed. This
results in little or no after touch.
If some of the notes have excess after-touch
6
the hammer
will let-off, check back
r
and then rise high enough to block on
the reed. This can be corrected by gluing one half (1/2) of
a
paper front rail punching of the desired thickness to the bottom
of the front of the white key.
NarE; If the whole action is this way, check paragraph on
key depth (Paragraph 2) and capstan screws (#3) before proceeding ..

AD .. TTJS'TING SPARPS
The key depth and after-touch of the sharps arc adjustad by
the screw under the front of each sharp. Turning this screw clock­
wise allows greater key depth and after touch; turning it counter­
clockwise allows less key depth and less after-touch.
6" SPOON ADJUS'TMENT (Fig. 700-K)
The butt spoon (Item 32, Fig
o
700-F,) has been factory-set
and should not require adjustment. The spoon is bent out just far
enough so the capstan screw, ( Item :rn, Fig. 700-F,) will escape
to the fly leather, (Item
37,
Fig. 700-F.)
The proper setting of the butt spoon is when the spoon clears
the fly stop cloth, (Item 35, Pig. 100-F,) by 1/64
,. after the key
is fully depressed and let-off has been obtained. Proper or full
check back will result.
