During Performance
Do not place the oboe on a table with its tone
holes facing down. Do not lean the oboe against
a wall with its tone holes facing down diago-
nally. In this way, you can reduce the chance of
moisture dripping from the tone holes during
performance, which could increase the risk of
body cracks.
If you leave the instrument – even for a short
period of time – place it in its case for protec-
tion and to avoid tripping others.
Maintenance After Performance
After you play your oboe, follow the procedure
below to clean the instrument.
Caution: Disassembling the Oboe
If you plan to disassemble the oboe into its
upper and lower joints and bell, do not hold
the instrument close to your face or near other
people. If a part detaches unexpectedly, it may
cause injury or damage.
Remove the reed tube, use a piece of gauze to
wipe away the moisture, then store it in a reed
case.
Use the supplied cleaning swab to clean inside
the main body. If moisture is left inside the
tube, it may result in cracking.
NOTICE
Th is cleaning swab is intended to be inserted and
removed from the bell side. It cannot be pulled out
from the top of the upper joint. When you feel the
resistance of the cleaning swab, pull it back to the
bell side. If pulled too strongly, the cleaning swab
may get stuck inside the instrument.
