Make sure you have the following supplies: (a) valve oil
(b) shop rag |
1. |
Loosen
the valve cap counter-clockwise and remove the valve assembly
from the valve casing. Wipe the valve off using the shop
rag.
|
2. |
Apply
oil in three locations. Make sure to do this over the shop
rag in order that excess oil does not create a mess. Replace
the valve assembly into the valve casing. Do not force it,
but turn it around in the casing to ensure even coverage.

Trumpets only
-Turn the valve cap clockwise until you hear a *click*. The
*click* is the sound of the valve guide (above) aligning
in the casing's groove.
Other brass instruments will align this guide visually before performing
the next step. In most cases this guide is nylon and can be easily
damaged if care is not taken.
|
4. |
Tighten the valve
cap clockwise until snug. The valve should be quiet during
operation. Clicking may result if the valve cap is not snug
enough.
