4.2 Attaching the Valve Adapter
The pump comes with an inflatable hose and various adapters for different valve types.
- Identify the valve type on your tire (Presta or Schrader).
- Screw the appropriate adapter (SV for Schrader, FV for Presta) onto the end of the inflatable hose.
- Screw the other end of the inflatable hose onto the pump's inflation port.
- For Schrader valves, you can directly screw the hose onto the tire valve. For Presta valves, you may need to use the FV adapter first.

- To switch between PSI and BAR units, press the '+' and '-' buttons simultaneously.
5.3 Inflation Process
- Connect the assembled inflatable hose to your tire valve. Ensure a secure connection to prevent air leakage.
- The display will show the current tire pressure.
- Set your desired target pressure using the '+' and '-' buttons.
- Short-press the power button (⏻) to start inflation. The pump will begin to inflate the tire.
- The pump will automatically stop once the preset pressure is reached.
- To stop inflation manually, short-press the power button (⏻) again.
- Carefully disconnect the hose from the tire valve.

Important Note:
- Avoid continuous operation for more than 3 minutes to prevent overheating. If the unit overheats, it may display 'HOT' and shut down automatically. Allow it to cool before resuming use.
- It is recommended to have the unit running (pushing air) when connecting to a tire that already has some air pressure. This helps prevent air from escaping while securing the connection.
6. Maintenance
- Cleaning: Wipe the pump with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
- Storage: Store the pump and its accessories in a cool, dry place, away from direct sunlight and extreme temperatures.
- Battery Care: For optimal battery life, charge the pump fully every 3-6 months if not in regular use.
- Silicone Cover: Keep the silicone protective cover on during use to protect against drops and manage heat dissipation.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not turn on | Low battery; Unit is off | Charge the pump fully; Long-press the power button to turn on. |
| Pump does not inflate / Error E3 displayed | Hose not securely connected; Valve blocked; Internal malfunction | Ensure hose is tightly screwed onto both pump and tire valve. Check for obstructions in the valve. If error persists, contact customer support. |
| Pump stops during inflation / 'HOT' displayed | Overheating due to prolonged use | Allow the pump to cool down for several minutes before resuming operation. Avoid continuous use for more than 3 minutes. |
| Inaccurate pressure reading | Loose connection; Sensor calibration variance | Ensure a tight connection to the tire valve. Note that a 1-2 PSI variance is normal for compact digital gauges. |
| Air leaks during inflation | Loose connection; Damaged valve adapter/hose | Tighten all connections. Inspect hose and adapters for damage and replace if necessary. |
