Maintenance

■ After Playing

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

using the procedure described below.

●

Valve slide maintenance

Depress the piston or lever that corresponds

to the valve slide you want to clean, and

remove the slide.

* Removing the valve slide without holding the

piston down creates a drop in air pressure

within the pipe, creating a suction which can

result in poor piston function or damage to

the inside of the pipe.

Remove moisture from the slide. Also, re-

move moisture from the water key.

Water Key

* 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.

●

Oil the pistons

As done before playing the instrument, apply

some valve oil to the pistons and move them

up and down a few times. (See page 24)

●

Oil the rotors (Rotary tuba only)

As done before playing the instrument, apply

some rotor spindle oil to the rotors and move

the levers a few times. (See page 24)

●

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.
