Maintenance

■ After playing

After playing, make sure that moisture or dirt is removed from the instrument using the

method described below.

Please consult with a wind instrument technician in regard to disassembling and mainte-

nance the spring trigger.

Valve slide maintenance

●

Depress the piston that corresponds to the

valve slide you want to clean, and remove the

slide.

3rd valve 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.

Remove moisture from the slide. Also, remove

moisture from the water key.

Main tuning slide

* 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.
