Before you use 1 Never use a metal type hammer or mallets to strike the sound column with. The sound column will break. 2 Always use the instrument on a flat, level surface. The instrument will not function properly on a sloped surface. 3 When assembling the stand, make sure each part is firmly attached, and there is no twisting or disfigurement in the frame. Also, make sure that all wing nuts are firmly tightened. 4 Use your toes to operate the damper pedal. Do not stand on or put your weight on the pedal. Doing so may cause the pedal to break. Damper Adjuster 5 Do not touch the damper adjuster (shown in the illustration left). The adjuster has been adjusted at the factory. Moving the adjuster may reault in the damper not functioning properly. 6 When playing the chime, make sure the caster brakes are firmly set and the chime stand does not move about. Sound Column Head Plug 7 Hit the Head Plug when playing the chime. Never hit the sound column (pipe) with the hammer. 8 Do not keep the chime in a place where high temperatures and high humidity are present. Doing so will result in the shortening of the instruments life. 9 For regular cleaning, wipe with a soft, dry cloth. Never wipe with thinner, or polishing preparations. Be careful when transporting 1 When transporting or moving the instrument, do not subject it to strong shocks 2 The sound column's pitch and/or tone may change if the columns are scratched or bent. Be careful. 3 When the instrument is to be transported over long distances, especially by vehicle, do so with the sound columns removed from the stand. The shape of the stand may change and the column's wire/ strings may be cut if the columns are not removed. 4 When attaching or removing the sound columns, do so in a place where there is sufficient room so that the columns do not come into contact with other objects. 5 After the sound columns are removed, wrap them in a soft cloth, etc., to prevent scratching, and then transport. 5
