Caution Injury or handicaps to persons caused by the disregard of warnings with this mark or, misuse of the instrument, may result in the loss of personal property. Please change cracked tone bars as soon as possible. Cracked tone bars have sharp edges that can cut hands. If the instrument is often moved, bolts, parts, etc., may become loose. After moving the instrument, check and make sure all bolts, parts, etc., are firmly fastened. Firmly tighten all loose items. Do not use the hammer for anything other than playing the instrument. It may be the cause of injury or accidents. Do not let children strike other, etc., with the mallet. Do not allow such dangerous behavior to take place. When assembling, be careful not to pinch your fingers or hands. Take special care when assembling rails and resonator pipes. Two persons should carry out this part of the assembly, double-checking as the assembly proceeds. PRECAUTIONS Please read the following instructions carefully before using your marimbas. ◆ Installation Location Use or storage in the following locations may cause damage, even when packaged. • In direct sunlight, such as near a window, or in a closed vehicle in daytime. • Near heating devices or in other locations subject to excessive heat. • In excessively cold environment. • In places with excessive humidity or dust. • Locations subject to vibrations. ◆ Handling • Never place an object on or lean against the instru- ment, as this may cause damage to the tone bars and frame parts or topple the instrument, which is extremely dangerous. • Do not use hand orchestra bell mallets or other hard objects on your marimbas. The resulting dents or scratches in the tone bars could impair the sound. (Wood tone bars) Also avoid hitting the tone bars hard with a hard mallet. The tone bars can crack. (Acoustalon tone bars) ◆ Moving and Transporting the Instrument • Before moving the instrument, make sure that the caster brakes are released. Also make sure to lift the instrument slightly when moving over rough surfaces. • When the instrument must be transported to a different location, disassemble it to the same state as when it was purchased (see page 26), taking care to pack each component properly. Disassembly steps are in the opposite order of assembly. ◆ When Not in Use • Always engage the caster brakes. ◆ Maintenance • The tone bars should be polished from time to time using a soft and dry cloth or silicone cloth. Stains that cannot be removed with a dry cloth may be wiped off using a small amount of ethyl alcohol. Never use thinner or benzene or a wet cloth for cleaning purplses. ◆ Keep This Manual for Future Reference • After reading, make sure to keep the manual in a safe place. Assembly Cautions • When assembling/disassembling the instrument, do so with at least two persons and follow the instructions outlined in this manual. Assembly in the wrong order can cause the pipes to drop which may result in an injury, impair the performance functionality of the instrument or cause noise. • Adjusting the playing height (see page 32) on the YM-410/410F/460/460F/2400/2400R should be done with at least two persons. • After final adjustment of the legs the fixing screws must be tightened securely to prevent loosening. Looseness may cause the instrument to shift during performance and can also cause noise and other problems. Retighten the screws from time to time. 23
