Care of Piston Valves

Oiling piston valves

The following procedures should be completed before and after playing the instrument:


•    Remove the upper screw cap (13) of the valve casing (14) and carefully pull the valve (12) out. Take care not to turn the valve (12) while removing.
•    Evenly distribute 2-3 drops of Miraphone piston valve oil onto the valve.
•    Re-insert the valve and screw the valve cap (13) back on.
•    Be sure to line the valve (12) up straight before inserting it into the outer casing (14).
•    Work the valves up and down rapidly to evenly distribute the oil over the surface.
•    Oil the valves again after playing. This protects the valve from oxydation and prolongs the life of the instrument.

Monthly cleaning of piston valves and valve casings (14)

•    Remove debris on the valves with a non-abrasive cloth (D).
•    Carefully wrap the cleaning rod (C) with the cleaning cloth (D) making sure that no metal is exposed.
•    Remove any dirt from inside the inner valve casing (14).

Valves and casings (14) are important components of the instrument; take care that you go slow in order to prevent damage to them.
