Precautions f or Wooden Bodies
Th e wooden body of a Yamaha oboe is made of from natural grenadilla, etc. For this reason,
the instrument is more susceptible to changes in temperature and humidity than are metal
or resin instruments. In particular, sudden changes in temperature or humidity may distort
the wood, resulting in body cracks or key malfunction. Th e body of the oboe is thicker and
more delicate than many other woodwind instruments.
To keep your instrument in optimal condition for a long period of time, please observe the
following precautions:
 In cold weather, before you play the oboe, allow it to adjust to room temperature. Never warm up
the instrument by blowing into it. Otherwise, drastic changes in temperature inside the body may
cause cracking or other damage.
 When the instrument is new, especially during the fi rst month or two, set it aside for extended pe-
riods of time. Play it little by little, for only about 20 to 30 minutes per day for the fi rst week, then
extend the duration gradually by about 10 minutes per day.
 After you play the instrument, remove moisture and dirt from inside the instrument using the
included cleaning swabs.
 After you play the instrument, store it in its case. Do not store it in places exposed to high tempera-
ture or humidity.
 Before you set the instrument down for a short time, remove moisture and dirt from it using a clean-
ing swab, and then place it on a stable surface with the keys facing up.
 Never leave damp gauze or cloth in the case.
Th e oboe is a very delicate instrument. Do not use it under the following conditions. Oth-
erwise, damage to the body may result.
Do not expose the instrument to:
 Direct sunlight for an extended period of time
* Refer to page 7, "Maintenance After Performance."
 Rain or excessive humidity
* Refer to page 10, "Caution: Storing the Oboe."
 Heat sources, such as stoves or fan heaters
 Cool air, such as from an air-conditioner
