3.1 Inflation
- Set Desired Pressure: Use the digital LCD display and the '+' and '-' buttons to set your target pressure in PSI or BAR. The pump supports up to 20 PSI.
- Start Inflation: Press the power button (usually marked with a power symbol) to begin inflation. The pump will operate in two stages:
- Stage 1 (High Speed): For rapid initial inflation at 350L/min.
- Stage 2 (High Pressure): Automatically switches to a higher pressure stage at 70L/min to reach the set PSI.
- Auto-Off Function: The pump will automatically shut off once the preset pressure is reached, preventing over-inflation and conserving energy.

5. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not turn on. | No power from 12V DC outlet; loose connection; blown fuse. | Check car's 12V outlet for power; ensure secure connection; check and replace pump's 12A fuse if necessary. |
| Pump not reaching set pressure. | Air leakage from hose/nozzle connection; inflatable valve not properly sealed. | Ensure all connections are tight; check inflatable valve for proper closure and seal. |
| Pump is excessively noisy during operation. | Normal operation during high-pressure stage; foreign object in fan. | Some noise is normal, especially in the second stage. If unusual, check for obstructions in air vents. |
| Pump overheats and shuts off. | Continuous operation for too long; blocked air vents. | Allow pump to cool down before resuming use; ensure air vents are clear. |
