Maintenance

■ Caring for your instrument after playing

To keep your instrument both looking and playing well, make sure you take proper

care of it after you have finished playing. When caring for the instrument, place it

on a table or, hold it securely in your hands, taking care not to drop it.

●

Valve Slide Maintenance

Remove the valve slides to remove any

moisture.

* Removing the valve slide without holding the

corresponding lever down creates a drop in

air pressure within the pipe, creating a

suction that can result in poor rotor function

or damage to the inside of the pipe.

If the instrument has a water key, remove

moisture from the water key too.

* The valve slides are made of brass or

nickel silver, which are both excellent at

resisting corrosion. However, corrosion

may appear if moisture is left in the

instrument for an extended period of time.

Please use caution.

●

Body Maintenance

Use a polishing cloth to gently wipe the

instrument's surface. If dirt or tarnish is obvi-

ous, the following products can be used.

For lacquer finishes...

Polishing cloth + lacquer polish

For silver plate...

Silver cloth + silver polish

For a beautiful shine, buff the instrument with

a silicone cloth.

■ Once a Week Maintenance

●

Rotor Maintenance

Remove the cap on the rotor valve and ap-

ply a little rotor spindle oil to the rotor bear-

ings.

* After applying the oil, remove the excess

oil. After applying oil, replace the cap and

move the lever a few times to distribute the

oil evenly.
