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 valves. - 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 the non-abrasive Miraphone Cleaning Cloth D onto the valves.
-
Carefully wrap the Cleaning Rod C with the Miraphone Cleaning Cloth (D).
-
Remove any dirt from inside the inner valve casing (14).
Maintenance of Valve Slides

• Rinse the slide with lukewarm water and dry thoroughly.
• Evenly distribute one 
La Trompa Slide Grease onto the valve slides.
• Special tuning trigger oil should be used for the tuning triggers.
• Replace all slides.
