Thank you for purchasing a YAMAHA Glockenspiel.
Before using this instrument we urge you to read
this Owner’s Manual thoroughly, and keep it in a
safe place for later reference.

組立ての前に、P.2「安全へのこころがけ」、P.3「ガススプリング取り扱いに関する注意事項」、P.4「末永くご使
用いただくために」、P.6「部品の確認」を必ずお読みください。

Before starting assembly, be sure to read the following sections; “PRECAUTIONS FOR HANDLING GAS
SPRING” pg 16, “TO GET THE MOST OUT OF YOUR INSTRUMENT” pg 17, “Parts Checklist” pg 19.

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.

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.

● 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

CAUTION

purchase. If your dealer is unable to assist you, please contact Yamaha directly.

2. Instructions for discarding the gas spring

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

specified 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 plastic 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.

TO GET THE MOST OUT OF YOUR INSTRUMENT

Please read the following instructions carefully before using your glockenspiel.

◆ 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

• Placing objects on or leaning against the instrument can damage the tone bars or the side frame.
This can also lead to the instrument falling over, etc. as described in the “Precautions” section. Never
do this as it is very dangerous.

• Do not use the glockenspiel’s mallets on a vibraphone, metalphone, etc. It can dent the tone bars or
cause damage, which can result in poor pitch.

◆ Transporting the Instrument

• When transporting the disassembled instrument, remove the tone bars and resonator pipes from the
glockenspiel and wrap them in a soft blanket, etc. for transport.

• When moving the instrument with its casters, make sure you adjust the instrument’s height to its
lowest level. This puts the instrument’s center of gravity at a lower point for greater stability while
moving.

• The instrument is sensitive to impacts. Treat the instrument with care when moving. Never drop or
throw the instrument.

• If it is necessary to lift the instrument while moving it, always do so with at least two persons and
using both hands to hold the side frames or legs. The instrument weighs about 36 kilograms.

◆ Maintenance

• The tone bars should be polished from time to time using a soft and dry cloth. Never use thinner or
benzene or a wet cloth for cleaning purpose.

◆ 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, make sure to follow the procedure 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.

A Note on the Gas Springs

Two of the YG2500’s four legs are equipped with gas
springs. One on the low pitch end on the
performer’s side and another on the high pitch end
on the audience side.
When loosening the slide guide bolts on the low
pitch end legs, the side of the frame not equipped
with the gas spring will be slightly lower however; this
is normal and not a sign of any problem.

When adjusting instrument height, use the guide
lines on the slide legs as a reference and adjust the
height so that the tone bars are parallel with the floor.
At this time, it will be necessary to slightly lift the side
of the frame without gas springs.
