5. Setup
- Power Connection: Insert the 12V DC power cable plug firmly into your vehicle's 12V accessory socket. Ensure the vehicle engine is running to provide adequate power and prevent battery drain.
- Hose Connection: Connect the high-pressure air hose to the inflator's air outlet port. Ensure it is securely tightened.
- Tyre Valve Connection: Remove the dust cap from the tyre valve. Screw the inflator's valve connector onto the tyre valve stem until it is finger-tight. Do not overtighten.
6. Operating Instructions
- Power On: Press the power button on the inflator. The digital display will illuminate, showing the current tyre pressure.
- Select Pressure Unit: Use the 'UNIT' button to cycle through available pressure units (e.g., PSI, BAR, KPA) until your desired unit is displayed.
- Set Target Pressure: Use the '+' and '-' buttons to adjust the target pressure to your vehicle's recommended level.
- Start Inflation: Press the 'START' button (or equivalent power/play button, refer to Figure 4.2 for specific button layout) to begin inflation. The inflator will automatically stop once the preset pressure is reached.
- Monitor Progress: Observe the digital display to monitor the pressure increase.
- Disconnect: Once inflation is complete and the inflator has stopped, unscrew the valve connector from the tyre valve stem. Replace the tyre valve dust cap. Disconnect the 12V power cable from the vehicle's accessory socket.

- Storage: Store the inflator and its accessories in a cool, dry place, away from direct sunlight and extreme temperatures. Use the provided storage bag to keep components organized and protected.
- Cable and Hose Inspection: Periodically inspect the power cable and air hose for any signs of damage, cracks, or fraying. Do not use the inflator if any damage is present.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Inflator does not power on. | No power from 12V socket; vehicle engine off; blown fuse in vehicle or inflator plug. | Ensure vehicle engine is running. Check 12V socket for power. Inspect and replace fuse if necessary. |
| Inflator runs but does not inflate. | Air hose not securely connected; tyre valve connector not fully screwed on; leak in hose or valve. | Tighten all connections. Check hose and valve for damage. |
| Inflator stops prematurely. | Overheating due to prolonged use; target pressure reached. | Allow unit to cool down for 15-20 minutes. Verify target pressure setting. |
| Inaccurate pressure reading. | Loose connection; unit calibration issue. | Ensure connections are tight. Compare reading with a known accurate gauge. If persistent, contact support. |
