About the adjuster
Be sure to use the adjuster underneath the pedals when-
ever the instrument is moved or when the pedals appear
to be unstable.
❍ Rotate the adjuster to lower it so that it is in firm contact
with the floor. If there is a gap between the pedals and
the floor, the pedals may be damaged. In particular when
placing the instrument on carpet, adjust this so that the
pedals firmly contact the floor.
