Checking hammer angle – spaces between
hammers must be equal and parallel at the “rest”
position.
If an error is detected then the shank can be heated
up and then carefully and very gently twisted back
into the correct alignment position.
*Do not use excessive force as this will stress the
flange and possibly damage the bushings.
After the hammer angle is corrected.

Space Hammers to Strings
For single and bi-chord notes, the hammers should
be centered under the strings.
*Note: Double-check that the soft pedal is adjusted
to allow the action to return all the way. Press the
soft pedal and insert a strip of paper between the
keyframe and the action stop block. Release the
soft pedal and the keyframe will return and trap
the paper strip. The paper should be firmly
gripped and cannot be pulled out until released by
again pressing the soft pedal.
