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 instrument, 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. ◆ Moving and Transporting the Instrument • Before moving the instrument, make sure that the caster brakes are released. Also make sure to lift the instru- ment 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 21.), 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. • 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. 19
