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 downstairs 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

• 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.

Handling

• 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.
• When handling the sound tubes, be careful not to drop them. Especially be careful when transporting 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 YCHS7006. For models other than YCHS7006, use the hex key you  own or consult qualified Yamaha service personnel.
• Keep small parts (such as wires, wire caps, screws, or bolts) away from small children who might accidentally swallow them.
• Replace the wire cap if it is damaged.
• Do not directly touch the frayed wire with your hand.
• Before playing, make sure to check that the tops of all the sound tubes are in line. 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 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.

• 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 temperatures 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 YCH6018 is attached to the YCHS7018, 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.

Preparation Before Playing

Play the chimes on a flat, level surface. In YCH7018 and YCHS7018, if some sound tubes are in contact with the damper felt while releasing the damper, adjust the four casters according to the steps below. In YCH6018, 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 YCHS7006, place the chimes where all sound tubes are not in contact with the guide plate.

Adjusting the Height of the Casters (YCH7018, YCHS7018)

1. Turn the lock nut on the upper of the caster counterclockwise to release the height lock.
2. Turn the bolt cap of each caster using the included tuning key to adjust the chime’s height from the floor.
Turning it clockwise raises the height away from the floor while turning it counterclockwise lowers it toward the floor.
3. After the height is adjusted, turn the lock nut clockwise to lock the height.

Adjusting the Damper Pedal (YCH7018, YCH6018, YCHS7018)
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.

Using the damper stopper
You can keep the damper release by pushing in the damper stopper while pressing the damper pedal. To release the damper stopper, press the damper pedal again.
NOTE
• When the depth of pressing the pedal is insufficient, the damper stopper cannot be pushed in. In this case, adjust the damper pedal position so that you can fully depress the pedal.

Troubleshooting

The damper does not release

• Stop pressing the damper pedal while pressing the damper stopper.
• When the depth of pressing the damper pedal is insufficient, the damper stopper cannot be pushed in. In this case, adjust the damper pedal position so that you can fully depress the pedal.
  Noise, poor sound
• Place the chimes on a flat, level surface.
• (YCH7018, YCHS7018 only) When the floor is not a level surface, adjust the height of the four casters.
• When the wire cap is damaged, replace it with a wire cap that is not damaged. Please contact qualified Yamaha service personnel about the wire cap (sold separately) for replacement.
