Setup
Charging the Device
Before first use, fully charge your Airmoto Tire Inflator. Connect the included USB-C charging cable to the charging port on the device and plug the other end into a compatible USB power source (e.g., wall adapter, car charger, power bank). The battery indicator on the display will show charging progress.
Note: For optimal battery performance it is recommended to fully charge the pump before every use. Battery performance can be affected by tire size, type, and ambient temperature.
Attaching the Air Hose
The air hose is stored conveniently inside the device for portability.
- Press the release button located at the bottom.
- Slide the air hose out from the top.
- Screw the air hose securely into the inflation port on the top of the Airmoto.

Operating Instructions
General Inflation Process
- Turn On: Press and hold the power button to turn on the Airmoto. The current pressure will be displayed.
- Select Unit: Press the 'M' button to cycle through pressure units: PSI, kPa, BAR, and KG/CM.
- Set Target Pressure: Use the '+' and '-' buttons to adjust the desired pressure. The display will show the target pressure.
- Connect to Valve: Attach the appropriate adapter (Schrader, Presta, Needle, or General Nozzle Cone) to the air hose, then securely connect it to the item's valve.
- Start Inflation: Press the 'Start' button (usually the central button) to begin inflation. The device will automatically stop when the target pressure is reached.
- Disconnect: Once inflation is complete, disconnect the hose from the valve and store the hose back inside the unit.

Maintenance
Battery Care
- Recharge the battery regularly, even if not in frequent use, to maintain battery health.
- Avoid completely draining the battery before recharging.
- Do not expose the device to extreme temperatures, as this can affect battery life and performance.
Cleaning and Storage
- Wipe the exterior of the device with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Ensure the device is dry before storing.
- Store the Airmoto and its accessories in the provided storage pouch in a cool, dry place, away from direct sunlight and moisture.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not turn on. | Low or no battery charge. | Charge the device fully using the USB-C cable. |
| Inflation is slow. | Large tire volume; low battery; extreme cold. | Ensure battery is fully charged. Inflation time varies with tire size and pressure difference. Operate in moderate temperatures if possible. |
| Device over-inflates slightly. | Minor calibration variance. | Set the target PSI 1-2 PSI lower than desired, then check with an external gauge if precision is critical. |
| Air leaks from connection. | Hose not securely attached; valve not fully engaged. | Ensure the air hose is screwed on tightly. Make sure the adapter is fully and correctly seated on the item's valve. |
| Device is noisy during operation. | Normal operation sound for an air compressor. | This is typical for portable air pumps. No action required unless the noise is excessive or unusual. |
