Operating Instructions
Inflating a tire or other item:
- Attach Air Hose: Screw the air hose nozzle onto the tire valve stem until it is finger-tight. The digital display will show the current tire pressure.
- Select Pressure Unit: Press the "R" button to cycle through available pressure units (PSI, BAR, KPA, KG/CM²). Choose the unit recommended by your vehicle manufacturer.
- Set Desired Pressure: Use the "+" and "-" buttons to adjust the target pressure. The display will flash while setting and then show the current pressure once set.
- Start Inflation: Flip the power switch to the "ON" position to begin inflation. The compressor will automatically stop once the preset pressure is reached.
- Monitor Progress: The digital display will show the pressure increasing during inflation.
- Disconnect: Once inflation is complete and the compressor has stopped, turn off the power switch and carefully unscrew the air hose from the tire valve. Replace the valve cap.

Using the LED Light
The built-in LED light can be activated independently by pressing the dedicated light button (if available, otherwise it might be integrated with the power switch or automatic). This is useful for nighttime operations or in low-light conditions.
Maintenance
- Cleaning: Wipe the compressor exterior with a damp cloth. Do not use harsh chemicals or abrasive cleaners. Ensure the device is unplugged before cleaning.
- Storage: Store the air compressor in a dry, cool place, away from direct sunlight and extreme temperatures. Ensure the power cord and air hose are neatly coiled to prevent damage.
- Inspection: Periodically check the power cord and air hose for any signs of wear, cuts, or damage. If damage is found, discontinue use and contact customer support.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Compressor does not turn on. | No power from vehicle socket; loose connection; vehicle engine not running. | Ensure vehicle engine is running. Check cigarette lighter socket for power (e.g., by plugging in another device). Ensure power cord is securely plugged in. Check vehicle's fuse for the cigarette lighter socket. |
| Compressor runs but does not inflate. | Air hose not securely attached to tire valve; air leak in hose or connection. | Ensure the air hose nozzle is tightly screwed onto the tire valve. Check for any visible damage or leaks in the air hose. |
| Compressor stops before reaching preset pressure. | Overheating protection activated; internal fault. | Turn off the compressor and allow it to cool down for at least 15-20 minutes. If the problem persists after cooling, contact customer support. |
| Inaccurate pressure reading. | Loose connection; sensor issue. | Ensure the air hose is securely attached. Compare reading with a known accurate tire gauge. If consistently inaccurate, contact customer support. |

Important Tire Pressure Information
Maintaining correct tire pressure is crucial for vehicle safety, fuel efficiency, and tire longevity. Both under-inflation and over-inflation can lead to serious issues.
Image: Visual representation of the risks associated with excessive tire pressure (burst tire), excessive low tire pressure (wheel wear, traffic accidents), and unstable tire pressure (loss of control).
- Excessive Tire Pressure: Can lead to a harsh ride, reduced tire contact with the road, and increased risk of tire burst.
- Excessive Low Tire Pressure: Causes increased rolling resistance, poor fuel economy, uneven tire wear, and potential for tire overheating and failure.
- Always check your vehicle's owner's manual or the sticker on the driver's side door jamb for the recommended tire pressure.
