About
the
Icons
For example:
Do not disassemble.
Hold the instrument by
the frame end and push
forward slowly.
When moving the instrument on its casters, only move across smooth, flat
surfaces. Hold the instrument by its frame end and push forward slowly.
When moving the instrument on its casters.
1. Avoid moving the instrument across surfaces that are sloped, uneven, or
graveled. The concert marimba can collapse and/or get out of control.
2. Do not run with the instrument. The instrument may become impossible to
stop, crash into a wall, and cause serious injury.
* The YM6100 weighs 106.5kg (234 lbs 12 oz).
Moving the instrument up or down stairs should never be done with the instrument assembled. Doing so is a danger as
parts can fall off, or you can loose balance causing the instrument to fall over. Only move the instrument after it has been
disassembled.
Caution
Injury or handicaps to persons caused by the disregard of warnings with this
mark or, misuse of the instrument, may result in the loss of personal property.
Please change cracked tone bars as soon as possible. Cracked tone bars have sharp edges that can cut hands.
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.
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.

Please observe the following instructions for proper handling of the gas spring.
Precautions for Handling Gas Spring
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 explo-
sion may occur, causing an injury.
[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 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.
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 unable to assist you, please contact Yamaha directly.
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 pres-
sure gas is sealed in it, disassembling it will cause a
high risk.
The gas spring is not rigid enough to prevent bending
due to unbalanced loads, do not attempt to bend it.
A poorly balanced load will cause the rod to bend, re-
sulting in defective operation.

Caution
Danger
Note that a nick in the piston rod or cylinder will
shorten the service life of the seal or result in defec-
tive operation. Do not hit the piston rod or cylinder.
Do not expose the gas spring to an excessively high
or low temperature. The allowable temperature
range for use is -20°C to 50°C.
Avoid using the instrument where it is exposed to to
rain, water or much dust. It will cause malfunction.
Do not apply an excessive force to lift the frame end
and pull off the gas spring from the leg. It will cause
malfunction or breakage.

Cautions
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 ex-
cessive 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. Also avoid hitting the tone
bars hard with a hard mallet. The tone bars can crack.
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 lo-
cation, 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.
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 in-
strument 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 prob-
lems. Retighten the screws from time to time.

n Tuning the Resonators.
The resonators are factory adjusted so that the optimum
resonance level is obtained at 23°C.
If the temperature differs due to playing conditions, the
resonators will require adjustment in order to obtain opti-
mum resonance.
q When the temperature is higher
• As the temperature rises, tone bar pitch lowers and
resonator pitch sharply increases making it neces-
sary to lower the pitch on the resonator to compen-
sate. In this case the resonating section of the tube
should be lengthened, or in other words, the regulator
should be set closer to the open end of the tube.
•Ordinarily, the regulator would be fitted into the pipe
as shown by “A” in the photo on the right, but it can be
reversed as illustrated by “B” in order to obtain maxi-
mum length.
w When the temperature is lower
• In this case the tube’s pitch must be raised. Contrary
to step q above, the resonating section of the tube
should be shortened, or in other words, the regulator
should be set further into the tube.
● Special Considerations
• For performances in large halls, etc., three
people are ideal for carrying out resonator
adjustments; one person to strike the tone
bars, a second to adjust the regulators, and
a third to signal the sound quality while
listening from the audience area.
•
The resonance of B/C and E/F notes should be
double-checked. Sound absorption by the
neighboring note can deteriorate resonance.
• Excessive noise between the cord and tone
bars can be eliminated by slightly loosening
cord tension.

Tone Bars Height Adjustment
Always adjust height with two persons, making
sure that both treble and bass sides are parallel.
* An extreme height at one end of the instrument
can damage the instrument.
While supporting the frame end of the leg by hand, loosen
the fixing bolt of the slide guide on both large end and
small end sides.
Adjust the height to the desired level and tighten the fixing
bolts securely.
When adjusting the height, use the lines on the slide guide
for reference and make the tone bars in parallel with the
floor surface.
