4. Instrucciones de configuración
- Attach Airflow Control Valve: Connect the airflow control valve to the air inlet of the spray gun body. Ensure a secure, airtight connection.
- Seleccionar cabezal atomizador: Choose the appropriate atomizing head size (1.2, 1.3, or 1.4) based on the coating material and desired finish.
- Conecte el cabezal atomizador: Align the selected atomizing head with the front of the spray gun body. Secure it by turning the quick-turn locking collar until it is firmly in place.
- Assemble PPS Series 2.0 Cup:
- Insert a disposable liner into the PPS Series 2.0 Cup.
- Pour the prepared coating material into the liner.
- Select the appropriate disposable lid (200 micron for most coatings, 125 micron for finer finishes) and snap it onto the liner.
- Attach the assembled PPS cup system to the spray gun body. Ensure the lid's connection point aligns with the atomizing head.
- Conectar el suministro de aire: Connect your air compressor hose to the airflow control valve. Ensure the air pressure is set according to the coating manufacturer's recommendations and the spray gun's specifications (maximum 130.53 PSI).

5. Instrucciones de funcionamiento
The 3M Performance Spray Gun is designed for high transfer efficiency and a large, adjustable fan pattern, providing a smooth trigger pull for consistent application.
- Ajustar la presión del aire: Use the airflow control valve to fine-tune the air pressure to achieve the desired spray pattern and atomization for your specific coating. Refer to the coating manufacturer's data sheet for recommended pressure settings.
- Ajustar el patrón del ventilador: The spray gun allows for adjustment of the fan pattern. Consult the gun's specific controls for widening or narrowing the spray.
- Prueba de pulverización: Before applying to the final surface, perform a test spray on a scrap piece of material to verify the spray pattern, atomization, and fluid output. Adjust settings as necessary.
- Solicitud: Maintain a consistent distance and speed while spraying to ensure an even coating. Overlap each pass by approximately 50% for uniform coverage.
- Control del disparador: Engage the trigger fully for consistent spray. Release the trigger at the end of each pass to avoid excessive material buildup.
6. Mantenimiento y limpieza
Uno de los avances clavetages of the 3M Performance Spray Gun system is its simplified cleaning process, as paint does not pass through the gun body.
- Desconecte el suministro de aire: Always disconnect the air supply from the spray gun before cleaning or disassembling.
- Remove PPS Cup System: Detach the PPS Series 2.0 Cup system from the spray gun body.
- Dispose of Liner and Lid: Remove the disposable liner and lid containing any remaining coating material. Dispose of these components according to local environmental regulations.
- Retire el cabezal atomizador: Unscrew the locking collar and remove the atomizing head.
- Clean Atomizing Head: The atomizing head can be cleaned with appropriate solvent or cleaning solution. Ensure all paint residue is removed from the nozzles and air passages. Allow to dry completely.
- Clean Spray Gun Body: Wipe down the exterior of the spray gun body with a clean cloth dampened with solvent, if necessary. Since paint does not pass through the gun body, internal cleaning is generally not required.
- Almacenamiento: Store the spray gun and components in a clean, dry environment.
Note: The replaceable atomizing heads are designed for multiple uses, provided they are cleaned thoroughly after each use.
