ASSEMBLY
n
Adjust the height of the tone bars.
While supporting the frame end of the leg by hand, loosen the xing bolt of the slide guide on both
large end and small end sides.
Adjust the height to the desired level and tighten the xing bolts securely.
When adjusting the height, use the lines on the slide guide for reference and make the tone bars in
parallel with the oor surface.
Upon completion of assembly, check to make sure that each bolt is tightened securely.
5-2. As YM-4600A does not have a resonance regulator, insert resonators into resonator holders as
shown below.
Fixing bolt
* The resonators are factory adjusted so that the optimum resonance level
is obtained at 23°C (73.4°F). If desirable resonance is not available due
to the temperature lower or higher than 23°C (73.4°F), adjust setting of
the resonators. Move the resonators to fit into shorter grooves when the
temperature is higher and into longer grooves when the temperature is lower.
