Maintenance advice

Dear Customer, your decision has been made for a German-quality handcrafted instrument. This instrument is provided with special Carbon-valves with many features. For example all valve-components are fully interchangeable, so that a replacement (in the event of ultimate wear) causes no problem, and can generally be undertaken by the player.

To keep your horn in superb condition, please follow this advice: Lubrication is required for the bearing at the linkage end (not under the valve cap) with a thin spindle oil on the end of a small screwdriver, using a thicker oil or grease for the lever linkages. This should be done once a month.

Finke valve-rotors usually work with no more than water lubricant – to prevent build-ups in the casing the rotors are installed with a drop of thin oil on the surface. If it becomes nevertheless necessary to oil the inside of the valves we recommend the products T2 from „La Trompa“ and "Blue Juice". They can be applicated through the slides.

Should the instrument not be used for a long time it should be rinsed through with distilled water before use. If a cleaning-brush has been used in this process, always rinse afterwards with plenty of water.

We recommend to clean lacquered Instruments with soft cloth, regular. To remove water drops (on the bell flair, etc), use lacquer-polish. These are available at your dealer. Special cleaning-sets are recommended to clean the inside-tubes.

Should it be necessary to remove the rotor for cleaning, do this as follows with the instruments lying in the players lap, not on a table. Take the bell section away from the body of the horn.


1. Place the instrument safely on your lap with the levers uppermost.

2. Remove the valve caps.

3. Turn the horn over so that the levers are beneath the instrument.

4. Remove the large screw from the center of the valve

5. Place the hammering rod in the hole from which the screw was removed.

6. With a small hammer gently tap the rod. This will dislodge the plate which holds the lower bearing ( see graphics ). After the bearing plate is free it is possible that the valve will free itself. If this is not the case one or two more very gentle taps should release it. Note the number on the rotor and plate!

7. Be careful when withdrawing the hammering rod not to dislodge the linkage arms as it can spring back and damage the instrument. Holding the linkage arm firmly, gently allow the spring to move it until it touches the body of the instrument.


1. Turn the horn so that the levers are uppermost again.

2. Put a few drops of thick oil on the surface of the rotor.

3. Insert the oiled rotor upside down into the rotor casing and rotate it in the casing while moving it in and out.

4. When the rotor is moving freely in the casing take it out and with a soft lint free cloth remove all traces of oil from the rotor and rotor casing paying particular attention to the corners of the casing.


1. Place one drop of thin oil on the surface of the rotor.

2. Reinsert the rotor the right way up.

3. Replace the bearing plate, supplied plastic collar over the bearing and tap the collar with a small hammer.

4. Replace the valve cap.

5. Replace the linkage onto the spindle, taking care that it is positioned correctly on the shaft.

6. Reinsert screw and tighten.
