2. Instruccions de seguretat
Observeu sempre les següents precaucions de seguretat per evitar lesions i danys a l'equip:
- Ensure the compressed air system is depressurized before installing or removing the regulator.
- Wear appropriate personal protective equipment (PPE), such as safety glasses, when working with compressed air.
- Do not exceed the maximum operating pressure specified for the regulator.
- Inspect the regulator and all connections for damage or leaks before each use.
- Use only clean, dry compressed air. Contaminants can damage the regulator.
- Do not modify the regulator in any way. Use only original replacement parts if repairs are necessary.
- Mantenir els nens i el personal no autoritzat lluny de l'àrea de treball.
3. Contingut del paquet
Verifiqueu que tots els elements siguin presents i no estiguin danyats en desempaquetar-los:

4. Producte acabatview
The YATO YT-2381 is a robust pressure regulator designed for industrial and workshop applications. It features a durable construction and an integrated manometer for precise pressure monitoring.
Components clau:
- Port d'entrada: Connects to the compressed air source.
- Port de sortida: Connects to the air tool or system requiring regulated pressure.
- Botó d'ajust: Used to set the desired output pressure.
- Manòmetre: Displays the current output pressure.
5. Configuració i instal·lació
Follow these steps for proper installation of your pressure regulator:
- Sistema de despressurització: Ensure the compressed air system is completely depressurized and shut off before beginning installation.
- Identifica els ports: Locate the inlet and outlet ports on the regulator. The inlet port typically has an arrow indicating the direction of airflow.
- Connect Inlet: Connect the compressed air supply line to the regulator's inlet port. Use appropriate thread sealant (e.g., PTFE tape) on all threaded connections to ensure an airtight seal.
- Connectar la presa de corrent: Connect your air tool or system to the regulator's outlet port. Again, use thread sealant.
- Muntatge (opcional): If desired, the regulator can be mounted to a wall or workbench using suitable brackets (not included) and fasteners. Ensure it is securely fastened.
- Manometer Installation (if separate): If the manometer is not pre-installed, carefully screw it into the designated port on the regulator. Do not overtighten.
- Comproveu les connexions: Double-check all connections for tightness and proper sealing.
6. Instruccions de funcionament
Once installed, operate the regulator as follows:
- Open Air Supply: Slowly open the main air supply valve to the system.
- Ajust de pressió: Turn the adjustment knob on the regulator clockwise to increase the output pressure, and counter-clockwise to decrease it. Observe the manometer to set the desired pressure.
- Lock Setting (if applicable): Some regulators have a locking mechanism (e.g., push-down knob) to secure the pressure setting. Engage this if available.
- Monitor de pressió: Regularly check the manometer during operation to ensure the pressure remains stable.
- Apagar: When finished, first close the air supply to the regulator, then depressurize the system by operating the air tool or opening a bleed valve until the manometer reads zero.
7. Manteniment
Regular maintenance ensures the longevity and optimal performance of your regulator:
- Diari: Check for visible leaks around connections and the regulator body.
- Setmanal/Mensual: Inspect the manometer for accuracy. If it appears faulty, replace it.
- Periòdicament: If the air supply is not filtered, internal components may become contaminated. Disassemble the regulator (refer to a qualified technician if unsure) and clean internal parts with a suitable solvent. Replace any worn seals or O-rings.
- Emmagatzematge: Guardeu el regulador en un lloc net i sec quan no l'utilitzeu.
8. Solució De Problemes
| Problema | Causa possible | Solució |
|---|---|---|
| No pressure at outlet | Air supply off; regulator adjustment knob fully counter-clockwise; clogged inlet filter. | Open air supply; turn adjustment knob clockwise; inspect and clean/replace filter. |
| La pressió fluctua | Inconsistent air supply; internal regulator issue; faulty manometer. | Check compressor stability; inspect regulator internals (professional service recommended); replace manometer. |
| Fugides d'aire | Loose connections; damaged seals/O-rings; cracked housing. | Tighten connections; replace seals/O-rings; replace regulator if housing is damaged. |
| Manometer reads incorrectly | Faulty manometer; incorrect installation. | Replace manometer; ensure manometer is screwed in correctly and not overtightened. |
