■ Cautions Relating to the Instrument The instrument's body is made from natural woods (spruce, maple, ebony, etc.) that are held together with glue. For this reason, there may be some cases in which sudden changes in temperature or humidity cause the glue to fail, or tuning or performance related problems. Please pay close attention to the environment and manner in which you use the instrument. • In summer or winter seasons, wait until the instrument has adjusted to room temperature before playing. Warning! • When tuning or changing the strings, never hold the instrument close to your face. If the string breaks unexpectedly, it may result in injury to the eyes or face. • Always change the strings one at a time, never all at once. The removal of all four strings from the instrument will result in the bridge collapsing, and the tailpiece falling off. Other problems may occur. • When tuning the strings, do not over loosen or over tighten the fine tuner. Doing so may result in damage to the instrument, or cause noise disturbances during performance. ■ Cautions Relating to Items Included with the Set and Accessories • The following parts are included in the set. Bow, case, and rosin. • When the case is equipped with a hygrometer: This hygrometer does not provide precise measurements so it should only be used as a guide when caring for the instrument. ● About the Bow • Using the supplied rosin, apply rosin to the bow hair before use. Make sure that the rosin is applied evenly over the entire length of the bow. (When applying rosin for the first time, apply abundantly.) • Always loosen the hair on the bow when the bow is not used. Rotate the button to adjust the bow hair tension. • Make sure that the bow hair is sufficiently loosened before placing the bow in the case. • Before storing any bow in the case other than the one that came with the instrument, make sure its length allows for proper and secure storage in the case. Warning! • The bow's shape can make it a danger to persons and objects close by. When playing the instrument make sure sufficient space is provided between you and the next person or object, etc. Never treat the bow in a rough manner, such as swinging or throwing the bow. 3
