manual abstract
2-1. First, insert the rail (2). A mark “B” is printed on the big end face of the rail (2) and the groove section of the end frame of the big end leg. * Do not insert one side of the rail all the way down first, but push both sides into grooves alternately little by little until both sides are inserted fully and stop. Next, in the same way, insert the rail (3) securely. A mark “C” is printed on the big end face of the rail (3) and the groove section of the end frame of the big end leg. “C” mark on the rail and end frame. Rail (2)“B” mark on the rail and end frame. Rail (3) Large end Small end Rail clamp 2-2. Engage the short rail clamp located at the center of the rail (3) with the rail (2). * Release the clamp from its holder, lift and move it to the rail (2) and push it down fully. Rail (3) Rail (2) Rail clamp ASSEMBLY c Attach the resonators. 3-1. Unbend the resonators, apply a hook and tighten the wing nut securely. * All the natural tone resonators are closed at the bottom. * When assembling the resonators, use care not cause any damage to them. Hook Wing nut 3-2. Insert the resonators into the resonator holders on the end frames in the same way as the rails. * Make sure not to confuse the natural tone resonators and accidental tone resonators. * Take care not to bump the resonators against the legs, etc. Resonators (Accidental tone side) Resonators (Natureal tone side) 27 ASSEMBLY vInsert the rails (1) and (4) into the end frames of the legs. 4-1. Insert the outer rails (1) and (4) in the same way as the inner rails (2) and (3). A mark “A” is printed on the big end face of the rail (1) and the groove section of the end frame of the big end leg, and a mark “D” for the rail (4). 4-2. Engage the rail clamps on rail (2) and rail (3) with rail (1) and rail (4) respectively. 4-3. Secure the resonators by fitting their hooks to the rail clamps engaged in Step 4-2. * Hooks are provided at 2 locations both on the natural tone side and the accidental tone side. * Make sure that each hook is securely fitted. Rail clamp Hook Rail (2) Rail (1) YM-5100A Only “A” mark on the rail and end frame. “D” mark on the rail and end frame. Rail (1) Rail (4) Large end Small end ASSEMBLY b Set the tone bars. 5-1. Set the natural tone bars first. With one person holding the suspension cords on the bass side and the other holding the suspension cords on the treble side securely with both hands, gently place the tone bars on the rails. Align each tone bar individually and hook its cord onto the corresponding post. After confirming that the cord is secured to every post, fix the tone bars by pulling the right and left cords forward from the large end side and hooking the two springs into each other. * When setting the tone bars, use care not to cause any damage to them. Small end Large end Suspension cord Post Suspension cord YM-5100A/4900A Only 5-2. Each of F#22, G23, G#24, A25 and A#26 resonators has a resonance regulator. While tapping each tone bar, move the resonance regulator to find the position where the best resonance is obtained and fix it there. * When fixing the resonance regulator, check to ensure that it is not aslant. Resonance regulator YM-4600A/4100A Only YM-4600A/4100A Only 5-2. As YM-4600A/4100A does not have a resonance regulator, insert resonators into resonator holders as shown below. * The resonators are factory adjusted so that the optimum resonance level is obtained at 23°C. If desirable resonance is not available due to the temperature lower or higher than 23°C, adjust setting of the resonators. Move the resonators to fit into longer grooves when the temperature is higher and into shorter grooves when the temperature is lower. Resonator holder Temperature Grooves to use Higher Short groove (“A” in the figure right) Around 23°C Center groove (“B”) Lower Long groove (“C”) A : For a higher temperature B : For a temperature around 23°C C : For a lower temperature n Adjust the height of the tone bars. While supporting the frame end of the leg by hand, loosen the fixing bolt of the slide guide on both large end and small end sides. Adjust the height to the desired level and tighten the fixing bolts securely. When adjusting the height, use the lines on the slide guide for reference and make the tone bars in parallel with the floor surface. Upon completion of assembly, check to make sure that each bolt is tightened securely. Fixing bolt SPECIFICATIONS/SCALE RANGE ¦ YM-5100A . Range: C16 – C76 (5 octave) . Bars: Honduras Rosewood .
