Caution
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.
When assembling, be careful not to pinch your fingers or hands. Take special care when assembling the long frame
and resonator pipes. Two persons should carry out this part of the assembly, double-checking as the assembly pro-
ceeds.
Please read the following instructions carefully before using your marimbas.
◆ Installation Location
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.
◆ Handling
• Never place an object on or lean against the instru-
ment, as this may cause damage to the tone bars and
frame parts or topple the instrument, which is ex-
tremely 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.
(Wood tone bars)
Also avoid hitting the tone bars hard with a hard mal-
let. The tone bars can crack. (Acoustalon tone bars)
◆ 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 differ-
ent location, disassemble it to the same state as when
it was purchased (see page 26), 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.
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.
PRECAUTIONS
◆ 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 thin-
ner 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 perfor-
mance functionality of the instrument or cause
noise.
• Adjusting the playing height (see page 32) on the
YM-410/410F/460/460F
should be done with at least two persons.
• 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.
