Resumen del manual
4. Slide the valve slide in and out a few times to distribute the grease evenly. Then wipe off any extra grease that comes off the slide. 27 Maintenance ¦ Twice Yearly Maintenance . Cleaning the Instrument 1. Prepare a brass soap water solution using between 10 to 15 parts warm water (78°F to 88°F) and 1 part brass soap. Before putting the instrument into the solution, remove the valve slides. 2. Apply some soap water solution to the brush on the end of flexible cleaner and use the cleaner to clean the inside of the instrument’s tubing. 3. After cleaning the instrument, use clean water to thoroughly rinse out the dirt and soap. 4. After completely removing all moisture with a gauze, apply oil and grease. Take Care When Cleaning Inside of the Instrument Never dismantle the rotors. Also, when rinsing the tubing with water, run water through the main tuning slides in the opposite direction of the airflow. If water is run through the instrument from the mouthpiece, dirt can become clogged in the valves causing the valves to become sluggish. 5. Apply some soap water solution to a mouthpiece brush and insert it into the throat to clean the mouthpiece, then thoroughly rinse it out with clean water. 28 Tying the Rotor Strings . Wind the string as shown in the illustration below, and tighten the string stopper screw. Wind the string around the screw in the same direction that the screw tightens. After winding, use the String Stopper Screw B to adjust the lever’s height.
