6. Operating Instructions

Follow these steps to inflate your items safely and effectively.

Figure 6.1: Easy-to-Use Inflation Steps.

1. Connect the Inflation Tube: Screw the flexible hose onto the compressor's inflation port.
2. Attach to Valve: Connect the appropriate adapter (if needed) and firmly press the inflation nozzle onto the tire valve or item's inflation port.
3. Power On and Set Pressure:
   • Long press the 'gear' button (often the power/mode button) for 3 seconds to wake up the tire pressure gauge and display the current pressure.
   • Short press the 'gear' button for 1 second to cycle through pressure units (PSI, BAR, KPA, KG/CM²). Select your desired unit.
   • Use the '+' and '-' keys to set your desired target pressure.
4. Start Inflation: Press the inflation switch key (often indicated by a power symbol or play symbol) to start the air pump. The compressor will automatically stop once the preset pressure is reached.
5. Disconnect: Once inflation is complete, quickly disconnect the nozzle from the valve to minimize air loss.
