[. . . ] The instrument may become impossible to stop, crash into a wall, and cause serious injury. If the instrument must be lifted, do so with at least two (2) persons. Holding the rail section can result in the instrument dropping or falling off. * Approximate weights for concert marimbas are given in the following chart. [. . . ] Locking screws fit into channels on leg pipes to eliminate slippage ad looseness. The YM-460/460F/2400/2400R offers a 5-step height adjustment that goes from 89cm at its lowest position, to 97cm at its highest. Since the YM410/410F is adjustable in 7-steps, from 76cm to 88cm, it promotes proper playing posture from children to adults. 5. Large Casters Large 100mm-diameter casters offer smoother transport. (YM-46 and 41 utilize 75mm-diameter casters). 2. Fine Tuning Tone bars are tuned by the highly refined ears and skills of our technicians and precision strobe tuners in an environmentally controlled room in which both temperature and humidity are kept constant. Precise tuning of the harmonic overtones, which determine timbre, results in stable pitch and tone without any unevenness. 6. 3-Step Height Adjustment for Resonator Pipes Resonator height can be adjusted in 3-steps to avoid loss of ideal resonance due to temperature changes. (The YM-41 only provides 2-step adjustment. ) 3. Easy Assembly/Disassembly The instrument is designed to offer easy assembly and disassembly to provide convenient storing and transport. The YM-460/460F/410D/46/2400/2400R utilize folding designs with two-section frames and pipes to provide the utmost in compact convenience. 24 02_ym460_en. indd 24 14/10/10 9:43 NOMENCLATURE ■ YM-460/460F/410/410F/46/41/2400/2400R * The illustration shows model YM-460.

A mark “B” is printed on the large end face of the rail (2) and the groove section of the frame end of the large 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. Tone bar height can be adjusted at this point. (1) Tone bar posts High register side C D B A Player side Frame end Bass side Audience side Rail (2) 2-2. After confirming that legs on the left and right sides are vertical, use the screw to connect the end of the stay to the hole for attaching the stay in the long frame (2) and firmly tighten the screw. When leg height is set low, use the hole closer to the center of the instrument, and when the leg height is high, use the outer hole and tighten the screw firmly. A mark “C” is printed on the large end face of the rail (3) and the groove section of the frame end of the large end leg. 2-4. Engage the short rail clamp located at the center of the rail (3) with the rail (2).

Make sure that the natural tone and accidental tone sides are properly assembled. 3-2. Insert the resonators into the resonator holders on the frame ends in the same way as the rails. Place the bass side of the resonators into the center grooves on the resonator holder. * 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 (Natural tone side) Resonators (Accidental tone side) * 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.
