Th umb Rest Adjustment and Instrument Maintenance

 Th e joint sections in particular tend to collect

moisture, which can cause cracking. Dry the

joints carefully with gauze.

* Even during playing sessions, remove moisture

from the body interior as frequently as pos-

sible.

 Keep the cleaning swab clean and dry.

 Once or twice a month, wipe the surface of the

instrument using a polishing cloth. Be careful

not to damage the keys or other parts.

 If you feel the keys are not moving well, use a

special key oil (sold separately). Do not apply

too much oil. Completely wipe any excess oil

from the key surfaces.

* Do not apply too much key oil.

* If you are unsure of where to apply the key oil,

consult the store where you purchased it.

 Use a tone hole cleaner to remove dirt from in-

side the tone holes and the spaces between and

underneath the keys. Be careful not to damage

the springs or pads.

 Use cleaning paper to remove dirt and moisture

from the pads. In particular, the octave tone

holes tend to collect moisture, which should be

removed as soon as possible.

NOTICE

Do not pull out the cleaning paper with the keys

closed. Th e cleaning paper may break and leave

pieces of paper, causing unbalanced adjustment.
