Maintenance
■
After playing
After playing, make sure that moisture or dirt is removed from the instrument using the
method described below.
●
Valve slide maintenance
1.
Depress the piston that corresponds to the
valve slide you want to clean, and remove the
slide.
* If you remove the valve slide without holding the
piston down, air pressure in the pipe drops creat-
ing a suction that can cause poor piston function
or damage to the inside of the pipe.
* If the instrument is equipped with a slide stopper
screw, loosen the screw before removing the slide.
2.
Remove moisture from the slide. Also, remove
moisture from the water key.

* Valve slides are made of brass or nickel silver
that is excellent at resisting corrosion however,
corrosion may appear if moisture is left in the
instrument for an extended period of time. Please
use caution.
●
Other maintenance
Apply some valve oil to the pistons and move the
piston up and down a few times, the same as you
do before playing the instrument.
Likewise, apply some rotor oil to the rotors on
rotary trumpets and move the levers a few times.

* Do not apply too much oil.

polishing cloth. If dirt or tarnish is obvious, the
following products can be used.
For lacquer finishes
