Slides and Their Funkcijos
Slides adjust tuning by lengtening or shortening the total tubing length. The main tuning slide the largest; valve sleides fine- tune each valve interwit.

Sticky or Slow Valves
Sticky valves are usally caused by old or neadekvati tepimo, dirt, or corcordission.
- Nutraukti valve arcelully, noting the orientation for reassembly. Most valves have a guide that must align wich a slot in the casing.
- Clean the valve and casing wich a lint- free cloth and mild soapy water if necessary. For stabborn buildup, use a synthetic bore brush designed for valve casings.
- Dry praly and inspect for burrs or nicks. If present, use a fine stone or crocos cloth to tto gently release them.
- Appy fresh valve oil evenly on te valve surface, then reinplact it in the readdy orientation. Work the valve up and down to distribute the oil.
