4.2 Attaching Adapters
The pump comes with a pre-attached car valve adapter. For other inflation needs, select the appropriate adapter from the integrated storage.
- For car tires, the pre-attached adapter is ready for use.
- For bicycle tires (Presta valve), screw the French valve adapter onto the car valve adapter.
- For sports balls, screw the ball needle onto the car valve adapter.
- For inflatable items, screw the balloon adapter onto the car valve adapter.
5. Operating Instructions
5.1 Powering On and Setting Pressure
- Press the power button to turn on the pump. The illuminated pressure gauge will display the current pressure.
- Use the Mode/Unit Selection button to cycle through pressure units (e.g., PSI, Bar, kPa).
- Use the Pressure Adjustment buttons (+/-) to set your desired target pressure.
5.2 Inflation Process
- Connect the appropriate adapter firmly to the valve of the item you wish to inflate.
- Ensure the connection is secure to prevent air leakage.
- Press the power button to start inflation. The pump will automatically stop once the preset target pressure is reached.
- Monitor the pressure gauge during inflation.
- Once inflation is complete, quickly disconnect the adapter from the valve to minimize air loss.

6. Maintenance
6.1 Cleaning
Regularly clean the exterior of the pump with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners. Ensure no dust or debris enters the air intake or exhaust vents.
6.2 Storage
Store the air pump in a dry, cool place, away from direct sunlight and moisture. Ensure all accessories are stored in their integrated compartments to prevent loss. Remove the battery pack if the tool is not used for an extended period.
7. Troubleshooting
If you encounter issues with your UniversalPump 18V, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not turn on. | Battery not inserted correctly or discharged. | Ensure battery is fully inserted and charged. |
| Pump runs but does not inflate. | Hose or adapter not securely connected; valve on item is faulty. | Check all connections for tightness. Inspect the item's valve for damage. |
| Air leaks when detaching adapter. | Common with screw-on valve adapters. | Inflate slightly above target pressure (e.g., 0.5-1 PSI higher) to compensate for minor air loss during disconnection. Disconnect quickly. |
| Inaccurate pressure reading. | Gauge calibration issue or external factors. | Compare reading with a known accurate gauge. If persistent, contact customer support. |
| Pump overheats and stops. | Extended continuous operation. | Allow the pump to cool down for several minutes before resuming operation. Avoid prolonged use without breaks. |
