Instrucións de configuración
1. Desembalaxe e inspección
Carefully remove all components from the packaging. Inspect for any shipping damage. Ensure all listed components are present.
2. Connecting the Air Hose
- Connect one end of the air hose to the compressor's air outlet. Ensure a secure, airtight connection.
- Connect the other end of the air hose to the air inlet fitting on the brad nailer.
- Verify all connections are tight to prevent air leaks.

3. Loading the Brad Nailer
- Ensure the air supply is disconnected from the nailer.
- Tire do seguidor do cargador cara atrás ata que quede bloqueado na posición aberta.
- Insert a strip of 18-gauge brad nails (3/4" to 2" in length) into the magazine with the points facing down.
- Solte o seguidor do cargador, permitíndolle empurrar os cravos cara adiante.
Instrucións de funcionamento
1. Air Compressor Operation
- Coloque o compresor sobre unha superficie estable e nivelada.
- Plug the compressor into a 120V power outlet.
- Xire o interruptor de alimentación á posición "ON". O compresor comezará a encher o depósito.
- Monitor the tank pressure gauge. The compressor is designed to automatically shut off when the maximum pressure (125 PSI) is reached. If it does not, immediately turn the power switch to "OFF".
- Adjust the output pressure using the regulator knob to the recommended operating pressure for your brad nailer (60-120 PSI).

2. Brad Nailer Operation
- Ensure the air hose is securely connected and the compressor is set to the desired operating pressure.
- Adjust Depth-of-Drive: Use the depth adjustment wheel on the nailer to control how deep the nail is driven into the material. Test on a scrap piece of material first.
- Place the nailer's nose against the workpiece where you want to drive a nail.
- Press down firmly on the nailer to engage the safety contact trip.
- Aperta o gatillo para disparar un cravo.
- Release the trigger and lift the nailer from the workpiece.

Mantemento
Regular maintenance ensures the longevity and optimal performance of your 3PLUS combo kit.
1. Air Compressor Maintenance
- Drenar o depósito de aire: After each use, or daily if used frequently, drain moisture from the air tank. Turn off the compressor, disconnect power, and open the drain valve at the bottom of the tank until all air and moisture are expelled. Close the drain valve.
- Bomba sen aceite: The HC0504G compressor features an oil-free pump, eliminating the need for oil changes or lubrication.
- Filtro de aire limpo: Periodically inspect and clean the air filter to ensure proper airflow.

2. Brad Nailer Maintenance
- Lubricación: Apply a few drops of pneumatic tool oil into the air inlet before each use.
- Limpeza: Keep the nailer clean and free of debris. Use compressed air to clear dust from the magazine and firing mechanism.
- Inspeccionar: Regularly check for loose screws, worn parts, or damage. Replace any damaged components immediately.
Resolución de problemas
| Problema | Causa posible | Solución |
|---|---|---|
| A cravadora non dispara ou dispara de xeito débil. | Low air pressure; no nails in magazine; jammed nails; worn O-rings. | Increase compressor pressure; load nails; clear jam using quick-release; inspect and replace O-rings if necessary. |
| As uñas atascanse con frecuencia. | Incorrect nail size; damaged nails; low air pressure; dirty magazine. | Use correct 18-gauge nails (3/4" to 2"); inspect nails for damage; increase air pressure; clean magazine. |
| Compressor runs continuously or does not build pressure. | Air leak; faulty pressure switch; drain valve open. | Check all connections for leaks; ensure drain valve is closed; contact customer support if pressure switch is suspected. |
| Compressor does not shut off automatically at max pressure. | Presostato defectuoso. | Immediately turn off the compressor manually. This is a safety concern. Contact customer support for repair or replacement of the pressure switch. |
