Instrucciones de funcionamiento
1. Comprobación de la presión de los neumáticos:
- Ensure the inflator is powered on and the correct pressure unit is selected.
- Retire la tapa de la válvula del neumático.
- Press the dual chuck firmly onto the tire valve stem. For Schrader valves, push straight on. For Presta valves, ensure the Presta side of the chuck is used. The gauge will display the current tire pressure.
- Read the pressure displayed on the LCD screen.
- Remove the chuck from the valve stem and replace the valve cap.

2. Inflating Tires:
- Follow steps 1-3 from "Checking Tire Pressure" to attach the inflator to the tire valve.
- Ensure your air compressor is turned on and supplying air.
- Press and hold the trigger on the inflator handle to begin inflation. The digital gauge will show the pressure increasing in real-time.
- Release the trigger once the desired pressure is reached.
- Remove the chuck from the valve stem and replace the valve cap.

3. Deflating Tires:
- Attach the inflator to the tire valve as described in "Checking Tire Pressure". The current pressure will be displayed.
- Press the air bleeder valve (small button or lever near the chuck) to release air from the tire.
- Monitor the digital display until the desired lower pressure is achieved.
- Release the air bleeder valve, then remove the chuck and replace the valve cap.
4. Using Lock-On Feature (for Presta/Schrader):
The chuck features a lever to secure it onto the valve stem for hands-free operation during inflation.
- Push the chuck onto the valve stem.
- Push the lever down to lock the chuck onto the valve stem.
- To unlock, pull the lever up.

Mantenimiento
- Limpieza: Limpie el dispositivo con un paño suave, damp Paño. No utilice limpiadores abrasivos ni sumerja la unidad en agua.
- Almacenamiento: Guarde el inflador en un lugar seco y fresco, alejado de la luz solar directa y de temperaturas extremas.
- Reemplazo de batería: Replace batteries when the low battery indicator appears on the LCD screen. Ensure proper battery disposal.
- Hose and Chuck Inspection: Regularly inspect the hose and chuck for any signs of wear, cracks, or damage. Replace if necessary to maintain air-tight seals.
Solución de problemas
| Problema | Posible causa | Solución |
|---|---|---|
| El medidor no se enciende. | Baterías muertas o instaladas incorrectamente. | Reemplace las baterías, asegurándose de la polaridad correcta. |
| Lectura de presión inexacta. | Improper connection to valve stem; unit needs recalibration (unlikely for new units). | Ensure chuck is firmly seated on the valve stem. If issues persist, contact customer support. |
| Fugas de aire durante el inflado. | Loose connection to air compressor; chuck not properly sealed on valve stem; damaged hose/chuck. | Tighten quick-connect fitting. Ensure chuck is fully engaged and locked onto the valve. Inspect hose and chuck for damage. |
| Presta side of dual chuck does not work. | Internal mechanism issue or blockage. | Ensure the Presta valve core is open. If the issue persists, contact customer support for assistance. |
