PRECAUTIONS FOR HANDLING GAS SPRING
Please observe the following instructions for proper handling of the gas spring.
1. Precautions for handling the gas spring
This gas spring requires no oil supply to its sliding
section. Additional oil will reduce the sealing durability
and cause the oil to leak.
Never apply any impact to the gas spring. It will cause
oil leakage, malfunction or breakage.
Never disassemble the gas spring. As a high pressure gas is sealed in it, disassembling it will cause a
high risk.
Note that there is not much rigidity in the bending direction. Depending on accuracy in its installation, the
bending load will cause the rod to bend, resulting in
malfunction.
● Do not apply a high tensile load to the gas spring as it will cause damage to the gas spring.
●
In the event of a failure, stop using the instrument and contact the shop of its purchase. If your dealer is
Note that a nick on the piston rod or cylinder will
shorten the service life of the sealing or cause a malfunction.
Do not expose the gas spring to an excessively high
or low temperature. The allowable temperature
range for use is -20°C to 80°C.
Avoid using the instrument where it is exposed to to
rain, water or much dust.
Do not apply an excessive force to lift the frame end
and pull off the gas spring from the leg.
Caution
unable to assist you, please contact Yamaha directly.
2. Instructions for discarding the gas
Make sure to observe the following instructions when discarding the gas spring.
As pressurized nitrogen gas is sealed in the gas spring, be sure to release before discarding it. Or an explosion may occur, causing an injury.
Danger
[PRECAUTIONS]
A. Do not crash.
B. Do not cut.
C. Do not make a hole anywhere other than the speci-
fied positions (q and w in the Fig.1).
D. Do not throw it in the fire.

[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 specified in the figure to release the gas and oil and then
make a hole w at the position as specified. (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 2 holes as shown above to release
the gas before discarding the gas spring.

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 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 22.), 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.
