PLEASE KEEP THIS MANUAL
PRECAUTIONS
Please read the following instructions carefully before using your vibes.
● Installation Location
● When Not in Use
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.
The driver and the controller, in particular, must be
protected from high humidity to avoid corrosion and
short circuit.
• Make sure to turn off the power switch and disconnect the AC adapter from the outlet.
• Always engage the caster brakes.
● Do Not Use Outdoors
Avoid using the instrument outdoors. Avoid exposure
to rain or moisture.
● 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 purposes.
● Keep This Manual for Future Reference
After reading, make sure to keep the manual in a safe
place.
● Power Supply
Make sure to use the supplied AC adapter. Use of
different adapters may cause damage not covered by
the warranty.
Assembly Cautions
● 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 hard orchestra bell mallets or other hard
objects on your vibes. The resulting dents or scratches
in the tone bars could impair the sound.
• Rough handling of the controller and/or the driver
may cause damage to the internal circuitry.
• Never try to disassemble the controller or driver, as
this may result in severe damage.
• When assembling/disassembling the instrument, make sure to follow the procedure outlined in this manual. Assembly in the wrong
order may impair the performance and functionality of the instrument or cause noise.
● Moving and Transporting the Instrument
• 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.
• Move the instrument carefully to avoid shocks. Before moving the instrument, make sure that the AC
adapter is disconnected and 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 make sure to fully disassemble it, taking
care to pack each component properly. Disassembly
steps are in the opposite order of assembly.
• Make sure to adjust the wire clip positions
after assembly. (YV-3910/3710/3700: P. 17)
• Height adjustment of the striking surface (YV3910/3710/3700: P. 18, YV-2700/2700G/
1600A/520: P 25) should be performed by AT
LEAST 2 PERSONS.

■ Dividable Parts and Collapsible Parts (YV-3910/3710 only)
The YV-3910’s/YV-3710’s large parts are designed to either divide or collapse. When the instrument is
broken down, its compact size makes it easy to transport and storage requires a minimum amount of space.
● Rails
The rails fold in from the center.
● Pedal Stay
The pedal stay divides into left and right sections and the pedal itself.
Loosen the 2 wing nuts and remove the stays from the pedal attachment.

10-1 Pedal Stroke Adjustment
Loosen the center rod fixing bolts to adjust the
protruding length of the center rod to the desired
pedal stroke, and retighten the bolts. The recommended stroke (distance between pedal and floor)
is 9/16" to 13/16" (1.5 to 2 cm).

10-2 Wire Clip Adjustment
For shipment the wire clip is initially set at a low position for packing reasons. For
normal use this clip should be adjusted as follows: With the pedal released loosen the
fixing bolt of the wire clip, shift the clip up until distance A in the illustration below is
1/16" to 1/8" (1 to 3 mm), and tighten the wing bold in this position.
The clip also allows setting the instrument to "half sustain damper" (slight continuous
damper effect) or "open damper"* by changing its position accordingly.
* To set to "open damper" depress the damper pedal fully to keep the damper open,
and set the wire clip to the highest position to lock the damper.
10-3 Damper Spring Adjustment
The damper effect (its pressing force on the tone bars) and the pedal force can be

This adjustment should always be performed by at least 2 persons.
To adjust the height of the tone bars, first remove the synchro belt, driver, controller,
tone bars, and resonators in the reverse order of steps ., ,, m, n, b, and v, and
loosen the center rod fixing bolts.
Loosen the slide leg fixing bolts on the high and low sound sides, while supporting the
frame ends by hand.
Lift the frame ends to the desired height and then securely tighten each fixing bolt,
aligning it with the corresponding notch of the slide leg. Bolt and notch are aligned
when the next higher notch is flush with the upper leg flange.
Slide Leg
Align notch with
upper flange.
Do not touch the notched
part during height adjustment to avoid injury.
* The fourth notch from top
corresponds to the standard
height setting.
After assembly, confirm that each bolt and screw is tightened securely.
When a slide leg fixing bolt is tightened in between two notches,
there is a danger of the slide leg slipping. Always make sure
that the slide legs are held securely.

Slip the round belt (fan belt) over the fan side pulley first, and then pull it over the flange of
the driver pulley.
*
Note For Service Personnel
If the belt cannot be mounted because the distance between the pulleys is too wide,
or the belt slips due to a too narrow pulley distance, loosen the two driver positioning
screws (see illustration below) to adjust the pulley distance (belt tension). Tighten the
screws securely after adjustment.

13
Adjust the pedal stroke. (Refer to YV-3910/3710/3700 assembly step 10-1 on page 17.)
14
After assembly, confirm that each bolt and screw is tightened securely.
15
Height adjustment should always be performed by at least 2 persons.
To adjust the height of the tone bars, first remove the round belt (fan belt), driver, controller and tone
bars*, and loosen the center rod fixing bolts. (* To remove the tone bars, disengage the springs on the
low sound side, and then unhook the string from the post.)
Support both frame ends by hand (do not touch the metal parts shown in the illustration), and loosen
the slide leg fixing bolts.
Frame
For height adjustment, make
sure to support the instrument
by the wooden frame. Do not
touch the metal parts.
Do not touch !
Lift the frame ends to the desired height and then securely tighten each slide leg fixing bolt, aligning
it with the corresponding notch of the slide leg. Bolt and notch are aligned when the next higher notch
is flush with the upper leg flange. (Refer to step , on page 23.)
When a slide leg fixing bolt is tightened in between two
notches, there is a danger of the slide leg slipping.
Always make sure that the slide legs are held securely.
16
This completes the assembly of the instrument.
To play, connect the supplied AC adapter to the DC 12V IN jack of the controller. (Refer to YV-3700
assembly procedure, "Power Supply", on page 19.)
