Instruções de operação
Operação geral
The control panel features a digital display, mode selection, and +/- buttons for adjusting pressure settings. The compressor has an automatic shut-off feature once the set pressure is reached.
High-Pressure Inflation (Tires)
- Defina a pressão desejada: Use the +/- buttons on the control panel to set the target PSI (Pounds per Square Inch) for your tire. Refer to your vehicle's owner's manual or tire sidewall for recommended pressure.
- Connect Chuck: Securely attach the high-pressure chuck to the tire valve stem. Ensure a tight seal to prevent air leakage.
- Inflação inicial: Press the START/STOP button to begin inflation. The compressor will automatically stop once the preset PSI is reached.
- Desconectar: Once inflation is complete, disconnect the chuck from the valve stem.

Low-Pressure Inflation/Deflation (Inflatables)
- Attach Large Hose: Connect the large diameter hose to the low-pressure inflation/deflation port. Select the appropriate nozzle for your inflatable item.
- Inflar/esvaziar: For inflation, connect the hose to the item and press the START/STOP button. For deflation, connect the hose to the item and select the deflation mode (if available, or reverse the hose connection if applicable to the specific model).
- Monitor: Monitor the inflation/deflation process visually. This mode does not have an automatic shut-off based on pressure.
