Make sure that another person is on hand to help with the
assembly and setup.
When assembling the piano stand, do not apply excessive
pressure on any part. To do so can cause metal parts to get
bent out of shape, and may damage wooden parts.
Be very careful, when you assemble and move the piano,
to make sure that you do not drop it on your hands or feet.
To move the piano, lift it carefully—all the while keeping
it level.
Fasten each screw tightly, then place the stand in a stable
and horizontal place.
Do not allow the pedal cord or power cable to get twisted
or pinched while assembling the stand.
At first, assemble the entire stand in a temporary fashion,
without really tightening the screws. Then, after checking
the overall alignment of the boards (and gently shifting
certain parts where necessary), go around and tightly
fasten each of the screws.
¡ Push the Pedal Board in the direction of the arrow t,
then fasten it with screws “a” y.

3. Fitting the Rear Board
5. Connecting the Pedal and Power Cords
¡ Position the Rear Board so the side on which the woodgrain is visible faces the same direction as the three
pedals, as shown in the illustration.
¡ Connect the pedal cord to the Pedal jack on the rear of the
piano.
¡ Connect the power cord to the power inlet on the piano,
then plug the other end into a wall socket.
Wood grain side
¡ Using screws “a,” fasten the Rear Board to the Side
Boards at right and left (two screws each at right and left).
Then, fasten the Rear Board to the Pedal Board with
screws “b” (four places). Observe the direction shown by
the arrow in the illustration.
6. Adjusting the Adjuster
¡ Lower the adjuster at the bottom of the pedal board (by
rotating it), so that the pedal board touches the floor. If
you have the piano placed on a carpet, lower it until it
pushes into the carpet.
Screw a
Screw b
4. Installing the Piano on the Stand
¡ Align the joint screws (one each at right and left) on the
bottom of the piano with the openings in the metal fittings
on the side board, then slide the piano forward until the
screws are held in place.
¡ Fasten the piano to the stand with the screw “c” (M5 X 20
mm) (one each for the right and left).
When Moving the Piano
Disconnect the power cord and raise the stand’s adjuster.
Then lift the piano while keeping it level, and move it
with care, so that you do not drop it on your feet, or get
your hands caught.
* When handling the piano, firmly grasp it at the front and
back. Be careful, so you do not get your fingers pinched.
