Trumpet Maintenance Tips

Assembling a Trumpet

The mouthpiece and mouthpiece receiver are easily damaged by improper assembly. Gently Insert the mouthpiece into the mouthpiece receiver, and then make a slight turn to secure it. Never force the mouthpiece in place. Avoid knocking or striking the mouthpiece inward. This can cause the mouthpiece to become permanently stuck. If this happens, take the horn to your local dealer or repair shop, they have a special tool to remove stuck mouthpieces. Never use pliers or other gripping tools to remove a stuck mouthpiece.

Disassembling a Trumpet

It is important to disassemble the instrument and place it in the case for storage after playing. Always use your case for storing the instrument after playing and for transporting. Be sure the mouthpiece and other accessories are secured, as they can scratch and dent your horn if they come loose during transportation. Do not put anything in the case that could place pressure on the instrument.


For your convenience, Wisemann instruments come with a standard outfit which provides a cleaning cloth, and a pair of gloves for daily use. We also recommend use of our Wisemann Brasswind Care Kit (optional outfit) to maintain the condition of your Wisemann brass instruments properly.

  1. Cleaning valves and valves casings

    Valve Oil should be applied (sparingly) to each valve. To apply valve oil, follow the procedure as described below:

      • Remove valve piston in a straight line. Do not twist piston.
      • Important:
        1. Valve pistons and casings are NOT interchangeable. Each valve pistons and casing have a number on them (1, 2, 3), make sure you place the valves in the correct casings.
        2. Apply 1-2 drops of valve oil to ensure adequate lubrication.
          Place the valve carefully back into the proper casing, aligning the valve guide with the guide slot. Tighten the top valve cap. Move piston up and down to ensure an even oil coating over the entire surface.
