Caution: Storing the Oboe
 Do not place the oboe on a table with its tone holes facing down.
Correct placement
 Th e oboe features perhaps the most complicated mechanism of all wind
instruments. A subtle change in temperature or humidity or the slightest
external pressure may damage keys or pad balance or precipitate changes
in key touch. We recommend that you take the instrument to your dealer
for adjustment once every two or three months.
 Do not place any object in the case that might apply pressure to the keys.
 Do not apply excessive force to the instrument or case.
 When you are not using the instrument, store it in its case and case cover.
To protect the instrument from changes in temperature and humidity,
store the case in a bag.
 Do not place the instrument in the vicinity of cooling or heating devices,
such as air conditioners or heaters.
