[. . . ] Holding the rail section can result in the instrument dropping or falling off. Never hold the instrument anywhere other than the frame ends.
* Approximate weights for concert marimbas are given in the following chart. YM-41 YM-46 41 kg (90 lbs 6 oz) 44 kg (97 lbs) YM-410 YM-410F YM-410D 49 kg (108 lbs) 55 kg (121 lbs 4 oz) 55 kg (121 lbs 4 oz) YM-460 YM-460F 55 kg (121 lbs 4 oz) 61 kg (134 lbs 8 oz)
Hold the instrument by the frame end and push forward slowly.
Moving the instrument up or down stairs should never be done with the instrument assembled. Doing so is a danger as parts can fall off, or you can loose balance causing the instrument to fall over. [. . . ] Since the YM-410/410F is adjustable in 7-steps, from 76cm to 88cm, it promotes proper playing posture from children to adults.
5. 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. Easy Assembly/Disassembly
The instrument is designed to offer easy assembly and disassembly to provide convenient storing and transport. The YM-460, 460F, 410D, and 46 utilize folding designs with two-section frames and pipes to provide the utmost in compact convenience.

ASSEMBLY
For safety, the instrument should be assembled by at least two persons in a location with sufficient space. We recommend to you to assemble the instrument on a soft rug or carpet.
z Connect the large and the small end legs using the reinforcement stays.
* YM-460/460F/410/410F: Before proceeding to the next step, make sure that the slide leg fixing bolts of the large and small end legs are securely fastened.
Leg (Large end) The tip of each slide leg fixing bolt must be tightly seated in one of the slide leg notches. Slide leg fixing bolt Slide leg fixing bolt Slide leg fixing bolt Leg (Small end)

c Attach the resonators.
3-1. Make sure that the natural tone and accidental tone sides are properly assembled. 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)

* 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.
