The following care and maintenance instructions are valid only for instruments with ATV-Valves:

A rotary valve instrument that is in frequent use, does not usually need to be oiled. Should the instrument sit for a longer
period of time without being played, the valves should then be oiled to prevent them from freezing up.

In this case, rinse the instrument with lukewarm water and then simply put a few drops of valve oil ( Miraphone Piston Valve Oil Miraphone Piston Valve Oil) into
and through the second valve in the valve section. Spread the oil into the valve by tipping the instrument and simultaneously
operating the valve keys. Be sure not to wash slide grease into the valve section with the fast oil. Valve bearings, however,
should be oiled at regular intervals (as described as follows).

Lubricating ATV-Valves on the bearing pin

Lubricate the ATV-Valves on the bores on the top and the botton of the valve (see number 6) as follows:

Miraphone Stift- und Lageröl Lubricate the valve bearings by applying oil first to the upper
bearing pin (6) and then to the lower bearing pin by removing the bottom screw cap (11) on the lower bearing (10) and
applying the oil through the small pin hole on the bearing pin.

damage to them.
