Tips for caring for your instrument: the baritone
1) Always consult your teacher if you are not sure how to apply valve oil.
2) The purpose of valve oil is to clean, lubricate and fill the air space inside the valves.
3) You should oil the valves of your Baritone before each time you play, preferably without completely removing the valves. This will prevent accidental damage to the pistons.
4) Remove the top cap and pull out the piston far enough to see the valve and apply enough oil to
fully cover the surface. (Do not oil the valves from the bottom caps) Using too
little oil will not properly lubricate your valves. Using too much oil will not
cause any damage to the Baritone.
5) Replace the valve without excessive rotation. As you lower the valve, slowly turn it clockwise until it locks into place. The oil will naturally distribute itself when the valves are depressed.
6) Confirm that the valve has been replaced properly by blowing through the instrument.
