ASSEMBLY

n
Adjust the height of the tone bars.
Make sure that this procedure is performed by at least two persons.
Reverse the assembly procedure going from steps b → v → c and remove the resonators and the
stay fixing bolts attached to the rail section (2) so that the stays can be moved.
With two persons, hold the instrument under the frame on both bass and treble sides, and loosen the
wing screws that lock the slide legs in place.
After determining the desired height, tighten the wing bolts so they fit into the channels on the slide legs
firmly fixing the legs in place. Use the next channel above as a guide to make sure the tone bars are
parallel with the floor.
Upon completion of assembly, check to make sure that each bolt is tightened securely.
When a slide leg fixing bolt is tightened in between two notches, there is a danger
of the slide leg slipping. Always make sure that the slide legs are held securely.
* Never attempt to adjust the height with the tone bars in place. It is very dangerous. Always make
sure that those parts are removed as described in the procedure above before adjusting the
height.
