PRECAUTIONS

PLEASE READ CAREFULLY BEFORE PROCEEDING

Please keep this manual in a safe and handy place for future reference.

WARNING

Always follow the basic precautions listed below to avoid the possibility of serious injury or even death from the chimes overturning, falling, the assembly running out of control or the parts falling.

Moving the instrument

• Lock the casters except when moving or transporting the chimes.
• Use a sufficient number of people when moving or transporting the chimes.
• The chimes should only be moved across smooth, flat surfaces when using the casters. Always move the chimes slowly, supporting the side frames as shown in the illustration. Never move the chimes on a sloped, unstable, or gravel surface.

• Never run when moving or transporting the chimes. Doing so can result in the chimes running out of control, hitting an obstacle or wall and causing serious injury.
• With the sound tubes attached, do not lift the chimes and do not go up or down stairs with the chimes. Only move the chimes after the unit has been disassembled.
• Stop use immediately if you notice any of the following abnormalities in the casters.
• One of the casters stops rotating when moving.
• The stoppers behave abnormally.
  These could cause the chimes to move or tip over, possibly causing injury.

Handling

• If a small child handles this instrument, make sure that the supervisor or instructor will accompany the child. Otherwise, the child might get injured.
• Before every playing, make sure to confirm that the wires are not damaged and that all wires are properly secured. Replace any wire that is damaged. Failure to do so might result in the sound tubes falling, and possibly causing injury.
• Do not install this product in an unstable location (on an uneven or unlevel surface, or on a wobbly table or pedestal). Otherwise, it might fall, causing injury.
• Do not lean against or climb on the instrument. Otherwise, it might fall or break, causing injury.

- Do not go near the chimes during an earthquake. Strong shaking during an earthquake could cause the chimes to move or tip over, possibly causing injury.

CAUTION

Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or damage to the instrument or other property. These precautions include, but are not limited to, the following:

Moving the instrument

- When transporting the chimes, make sure that all caster locks are released.

Assembly

• When removing the chimes from the package, raising the chimes and assembling the stand, always use two or more people. Failure to do so might result in damage to the chimes or the chimes overturning, and possibly causing injury.
• Assemble the chimes in the proper sequence by following the assembly instructions in this manual. Failure to do so might result in chimes overturning, and possibly causing injury.
• Make sure to tighten the screws or bolts regularly. Failure to do so might result in misalignment of the chimes during playing, noises, possibly causing injury.
• Use only the specified chime stand. Failure to do so might result in the sound tubes falling, and possibly causing injury.
• Pay attention to the sharp edges or inside surfaces of the tubes, which might injure your fingers.

Handling

• When handling the sound tubes, be careful not to drop them. Especially be careful when transporting and attaching or removing the sound tubes, and when replacing the wires. Failure to do so may result in damage to the sound tubes, possibly causing injury.
• Do not recklessly swing the chime mallets. It may injure people or damage surrounding objects.
• Make sure to periodically check that the screws and bolts are not loose. Use the included hex key of the YCHS7106. For models other than YCHS7106, use the hex key you own or consult qualified Yamaha service personnel.
• Keep small parts, such as bolts, away from small children. Otherwise, a child might accidentally swallow them.
• If the wires or Teflon tubes are damaged, replace them immediately. Consult your Yamaha dealer for replacements and repair.
• Do not directly touch the frayed wire with your hand.

- Before playing the instrument, make sure that the wires for all of the sound tubes are attached to the stand properly. Failure to do so might result in the sound tubes falling, and possibly causing injury.

- Do not insert your finger, hand or foot in any gaps on the casters, height adjustment mechanism or active part of dampers. Doing so can result in pinching your finger/hand/foot, and possibly causing injury.

NOTICE

• When transporting the chimes, remove all sound tubes from the chime stand. After the sound tubes are removed, wrap them in a soft cloth, etc., to prevent scratching while transporting.
• When playing or storing the instrument, install all of the sound tubes. If only some of them are installed, the damper felt might deteriorate quickly or inconsistently.
• When attaching or removing the sound tubes, do so in a place where there is sufficient room, so that the tubes do not come into contact with other objects.
• When transporting or moving the instrument, do not subject it to strong shocks.
• The sound tube's pitch and/or tone may change if the tubes are scratched or bent. Be careful to avoid this.
• Hit the Head cap when playing the chime. Never directly hit the sound tube with the chime mallet. Failure to do so might result in damage to the sound tube.

Chime mallet Head cap YAMAHA Sound tube

• Do not use hammers other than chime mallets for playing the chimes. Doing so can result in damage to the sound tube.
• Do not use the chime mallets for anything other than playing the chimes.
• Always use the chimes on a flat, level surface. The chimes will not function properly on a sloped surface.
• Do not rest your weight, or place heavy objects on the damper pedal. Doing so can result in damage to the damper.
• When not playing the chimes, contact the damper with the sound tubes. Doing so prevents resonance of the sound tubes from the acoustic sound of surrounding instruments.
• Do not keep the chimes in an environment with high temperature or high humidity.
• When cleaning the product, wipe with a soft and dry cloth. Do not use thinners or polishing preparations.

INFORMATION

• When exposed to the air, the sound tubes may discolor over time, but this does not affect the sound quality.
• Use the sound tube and chime stand in the correct combination. When a sound tube for the YCH6118 is attached to the YCHS7118, the reverberation cannot be shortened by the damper pedal.
• The illustrations as shown in this manual are for instructional purposes only, and may appear somewhat different from those on your instrument.

4. Tighten the two bolts temporarily fixed in step 3.

5. Attach the sound tubes to the frame according to the "Attaching the Sound Tubes" (page 7).

NOTE

- If you use sound tubes YCHT7149A or YCHT7150A# (made-to-order product), the sound tubes may contact the base bar, for example, during transport. In such cases, attach the included rubber cushions to the base bar to provide a cushion.

■ Attaching the Sound Tubes

Install the sound tubes with the damper released.

1. Put the sound tubes on a stable, flat, level surface.

To prevent damage to the tubes, place a soft cloth on the floor where the tubes will be placed.

1. Remove the protective film that was applied to the sound tube surface.
   3.Face the name of the note that appears on each sound tube toward the performer. Insert the wire into the groove on the hanger pin to one side of the sound tube; then hook it around the round rivet located on top of the hanger; and then insert the wire into the groove on the hanger pin to the other side of the sound tube.

Make sure that the wire is hooked securely by the round rivet and both hanger pins.

Hanger pin Name of the note Sound tube Round rivet Wire Hanger pin Teflon tube

Sleeve Round rivet Wire Teflon tube Teflon tube Hanger pin Hanger pin

NOTICE

- Adjust the wire position so that the part covered by the Teflon tube will be hooked by the hanger pins, and so that the sleeve on the wire will not interfere with either the round rivet or the sound tube. (See the recommended position in the illustration above.)

To hook sound tubes on the hanger more easily and smoothly, we recommend that you start hanging the sound tubes for accidental tones (C#53 – D#67), and then hang the sound tubes for natural tones (C52 – F69). In this way, the sound tubes will be unlikely to interfere with each other.

YCH7118, YCH6118, YCHS7118

Generally, arrange the sound tubes as shown below. The places filled with gray are not used.

To disassemble the instrument, follow the installation steps in reverse order.

Preparation Before Playing

Play the chimes on a flat, level surface.

In YCH7118, YCH6118 and YCHS7118, if some sound tubes are in contact with the damper felt even while the damper is released, place the chimes on a flat, level surface.

For the YCHS7106, place the chimes where all sound tubes are not in contact with the guide plate.

Sound tube Damper felt In contact

■ Adjusting the Damper Pedal (YCH7118, YCH6118, YCHS7118)

The damper holds the sound tubes with the damper felt to shorten the reverberation of the chime sound. While pressing the damper pedal, the damper is released and reverberations are heard. When you stop pressing the damper pedal, the damper will work and the reverberation will stop.

The position of the damper pedal can be adjusted by the following steps.

1. Loosen the fixing bolt.

2. Adjust the position of the damper pedal.

3. Tighten the fixing bolt to fix the damper pedal.
