Caution
Disregard of cautions with this mark or misuse may result
in personal injury or the loss of personal property.
Precautions Regarding the Gas Spring
Please observe the following instructions for proper handling of the gas spring.
* Refer to page 13 for gas spring removal.
Caution
Disregard of cautions with this mark or misuse may
result in personal injury or the loss of personal property.
Be careful not to pinch your
fi
ngers or hands when
assembling.
Doing so may cause injury due to pinched
fi
ngers, etc.
When assembling legs, reinforcement stays, and reso-
nator pipes, use two persons taking special care to
double-check each other as the assembly proceeds.
Always make sure that the wing bolts and wing nuts
are
fi
rmly tightened to prevent parts from becoming
loose during performance.
Using the instrument with loose bolts and nuts can
cause trouble during performance such as unexpected
movement, etc., or parts falling off during transport re-
sulting in injury.
Refer to the instructions when assembling the rack.
Height adjustment should always be performed with
at least two persons.
Make sure that all procedures described in the manual
are followed when assembling the rack and attaching
or removing the xylophone. Disobeying the procedures
can result in parts falling off from the rack during as-
sembly, which can be dangerous. Also, height adjust-
ment should always be performed by at least two
persons. If it is absolutely necessary to adjust height by
one person, do not make adjustments of more than two
notches on the slide guides at a time (see page 13).
Handling
Only use genuine Yamaha clamps.
Never use clamps that do not properly
fi
t on the rack pipe,
etc. when making attachments. Doing so can cause the rack
to overturn or instruments to fall off resulting in serious injury.
Never loosen the slide guide
fi
xing bolt when the xy-
lophone is not mounted on the rack.
Never loosen the slide guide
fi
xing bolts when the xylophone
is not mounted on the rack or when the legs are not attached
to the rack (except for when removing the gas spring). Doing
so is extremely dangerous because the rack frame (see page
11) can rise suddenly causing an accident or injury.
Limits to attaching optional instruments
The total weight of optional instruments must not ex-
ceed 18kg. Attaching more weight can result in the
entire rack overturning, becoming damaged, or the
optional instruments falling off or becoming damaged.
This is extremely dangerous.
Do not touch cracked tone bars.
Cracked tone bars have sharp edges that can cut hands.
Please change cracked tone bars as soon as possible.
Do not use the mallets for any other purpose than
playing the instrument.
Misuse of the mallets may result in unexpected injury or
accidents.
●
In the event of a failure, stop using the instrument and contact the
shop where you purchased it. If your dealer is unable to assist you,
please contact Yamaha directly as per enclosure.
Cautions when discarding the gas spring
Pressurized nitrogen gas is sealed inside
of the gas spring. Be sure to release the
gas before discarding the gas spring, or
an explosion can occur, causing injury.
[Cautions]
• Do not push.
• Do not cut the gas spring.
• Do not throw the gas spring into a
fi
re.
• Do not make a hole anywhere in the gas
spring other than in the speci
fi
ed posi-
tions (
q
and
w
in the
fi
gure below).
[Discarding procedure]
1. Put the gas spring in a plastic bag. Using
a drill of 2 to 3 mm, make a hole
q
from
outside of the plastic bag at the position as
speci
fi
ed in the
fi
gure to release the gas and
oil and then make a hole
w
at the position
as speci
fi
ed.
(Be sure to make holes in the
order of
q
and
w
.)
2. If a vinyl bag is not used, the oil and drill
chips will spread. (In such a case, wear eye
protection glasses. )

* Drill two holes, as shown above, to release

Danger!
Disregarding any caution with this
mark can place you in imminent danger
resulting in death or serious injury.
Handling
Never lubricate the moving parts on the gas spring.
Lubricating the gas spring will reduce the durability of the seal and
cause oil leakage.
Do not expose to impacts.
Doing so will cause oil leakage, malfunction, or damage.
Never dismantle.
High-pressure gas is sealed inside of the gas spring, so any at-
tempt to disassemble it is extremely dangerous.
Do not bend.
The rod is susceptible to bending from directional loads. A poorly bal-
anced load placed on the rod can result in bending and malfunction.
Do not hit.
Hitting the piston rod or cylinder can shorten the life of the seal or
result in malfunction.
Do not expose the instrument to excessively high or low temperatures.
Doing so can cause malfunction. Use the instrument only in tem-
peratures ranging from -20ºC to 50ºC.
Do not expose the instrument to rain, moisture or dust.
Doing so can cause malfunction.
Do not use excessive force to lift the side frame, which can
pull the gas spring out of the leg.
Doing so can cause malfunction or damage the instrument.
Do not apply a high tensile load on the gas spring.
Doing so can cause malfunction or damage the instrument.
