Always follow the basic precautions listed below to avoid the possibility of physical injury to you
or others, or damage to the instrument or other property. These precautions include, but are not
limited to, the following:
• Never place any objects on the instrument. Doing so can
damage the tone bars or frame.
• Please change cracked tone bars as soon as possible.
Cracked tone bars have sharp edges that can cut hands.
• 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.
• Do not use hand orchestra bell mallets or other hard objects
on your xylophones. The resulting dents or scratches in the
tone bars could impair the sound. The xylophone's tone bars
in particular, are made of a soft wood specially chosen for its
distinctively deep timbre, so please take care. Also avoid hit-
ting the tone bars hard with a hard mallet. The tone bars can
Yamaha cannot be held responsible for damage caused by improper use or modifications to the instrument.
• 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.
• Use or storage in the following locations may cause dam-
age, 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.
- Locations where the instrument can be exposed to rain
or moisture.
• Always use two or more persons when assembling the legs
and stays, and when setting the resonators. Disregarding this
can result in injured hands or fingers, and parts may fall over
or get scratched.
• 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 purposes.
When moving the instrument

location, disassemble it to the same state as when it was
purchased, taking care to pack each component properly.
Disassembly steps are in the opposite order of assembly.
• Handle the instrument carefully when moving. Never drop
or throw. The instrument is sensitive to shocks and may
become damaged.
• 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.

cords are not hooked in the tone bar posts. Make sure the
cords are properly attached.
