5. Operating Instructions
5.1 General Inflation Procedure
- Connect to Item: Attach the nozzle of the air hose firmly to the valve stem of the item you wish to inflate. Ensure a tight seal to prevent air leakage.
- Select Pressure Unit: Press the 'UNIT' button to cycle through available pressure units (PSI, BAR, KPA) until your desired unit is displayed.
- Set Target Pressure: Use the '+' and '-' buttons to adjust the target pressure. The display will show the current pressure and the set target pressure.
- Start Inflation: Press the 'START/PAUSE' button to begin inflation. The inflator will automatically stop once the target pressure is reached.
- Disconnect: Once inflation is complete and the device has stopped, quickly disconnect the air hose from the item. A small amount of air may escape during disconnection.
5.2 Preset Modes
The inflator features four preset modes for common inflation tasks. Press the 'MODE' button to cycle through these presets:
- Car Mode: Optimized for standard vehicle tires.
- Motorcycle Mode: Suitable for motorcycle tires.
- Bicycle Mode: For bicycle tires.
- Ball Mode: For sports balls.
You can adjust the target pressure within each preset mode if needed. The device will remember your last set pressure for each mode.
5.3 Auto-Stop Function
Both the VORTEX S6 and ZEPHYR S3 models are equipped with an auto-stop feature. Once the set target pressure is reached, the inflator will automatically power off, preventing over-inflation and ensuring precise pressure.
