Besides voiding the warranty, modification of the instrument may make repairs impossible. In regards to brass instruments with a plate finish, the color of the finish may change over time however, it should be of no concern in regards to the instrument's performance. Discoloration in its early stage can easily be removed with maintenance. [. . . ] Do not apply any excessive force, or bump the instrument so as to dent or damage it. Applying Oil Apply oil to the pistons Applying Oil To The Rotors (Rotary Trumpets Only) 1. Unscrew the valve cap and pull the piston straight out of the valve casing until about half of the valve piston is exposed. ton. Valve oil Piston 1. Hold the lever down and remove the valve slide. * If the valve slide is removed without holding the lever down, air pressure in the pipe drops creating a suction that can cause poor rotor function or damage to the inside of the pipe. 2. Apply a few drops of valve oil on the pis- 2. Apply some rotor oil to the rotor and then move the lever a few times to distribute the oil evenly. * Do not apply too much oil. Slowly, return the piston into the valve casing. At this time, make sure the number stamped on the piston is facing the mouthpiece. After the valve cap is tightened firmly, move the piston up and down a few times to distribute the oil over the piston evenly. Number * To keep oil from mixing with the slide grease or dirt inside of the pipe, hold the oil container's spout so that is does not come into contact with the inner walls of the pipe. * Since the oil container's spout is metallic, be careful not to let the spout come into direct contact with the rotor. 3. Hold the lever down and replace the valve slide. * If all pistons have been removed from the valve casings, make sure the number stamped on the piston matches the number stamped on the casing before returning the piston into the valve casing. * The pistons must be oiled for them to function properly and smoothly. * If you replace the valve slide without holding the lever down, pressure built up inside the pipe can cause poor rotor function or damage to the inside of the pipe. 18 Before You Play Applying Oil To The Valve Slides 1. * If air does not pass through the instrument when the piston is fully depressed, the piston may be placed in the wrong valve casing. Make sure that the numbers stamped on the piston and valve casing match. The piston is the most important part of the trumpet. Never treat the pistons roughly, drop the piston, or let the piston fall, etc. If the piston becomes damaged or dented, never return it to the valve casing. Contact the dealer from whom you purchased the instrument. 22 Maintenance Rotor maintenance (Rotary trumpets only) Valve slide maintenance 1. Remove the rotary valve cap and apply some rotor spindle oil to the place to the spindle in the center of the rotor. Rotor spindle oil 1. Apply a thin coating of slide grease to the main tuning slide, 2nd valve slide, and valve slides that are not equipped with a slide trigger. Slide grease Main tuning slide 2. Apply some rotor spindle oil to point where the rotor rotates. Replace the rotary valve cap and move the lever a few times to distribute the oil evenly. 2. Slide the main tuning slide back and forth a few times to distribute the grease evenly. Main tuning slide 3. Apply some lever oil to the lever shaft. Lever oil 3. On the 1st and 3rd valves, which are equipped with slide triggers, apply a small amount of tuning slide oil to the tuning slides. Tuning slide oil Apply here. 3rd Valve Slide 23 Maintenance Twice Yearly Maintenance Cleaning the instrument Cleaning the mouthpiece 1. 1. Make a brass soap water solution. [. . . ] Rinse the mouthpiece out with clean water. 2. With the instrument removed from the water, apply some soap water solution to a flexible cleaner and use the cleaner to clean the inside of the instrument's pipes. Mouthpiece brush Flexible cleaner 3. After cleaning the instrument, use clean water and thoroughly rinse out the brass soap water solution. Thoroughly remove dirt and apply some slide grease that matches the type of slide, or apply some tuning slide oil. [. . . ]
