5. Operating Instructions
Once the inflator is set up, proceed with inflation:
- Set Desired Pressure: The digital display will show the current tire pressure. Use the '+' and '-' buttons to set your desired target pressure. You can switch between units (PSI, BAR, KPA, KG/CM²) using the 'M' button. Refer to your vehicle's manual or tire sidewall for recommended pressure.
- Start Inflation: Flip the power switch to the 'ON' position. The compressor will begin inflating.
- Automatic Shut-Off: The inflator will automatically stop once the preset pressure is reached.
- Disconnect: Turn off the power switch, then disconnect the 12V power plug and unscrew the air hose from the tire valve.
Using the LED Light:
The inflator is equipped with an LED light for use in low-light conditions or emergencies.
- White Light: Provides illumination for working in the dark.
- Red Warning Light: Can be activated for emergency signaling.

6. Maintenance
Proper maintenance ensures the longevity and reliable operation of your tire inflator.
- Cleaning: Wipe the exterior of the inflator with a damp cloth. Do not use harsh chemicals or immerse the unit in water.
- Storage: Store the inflator in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure the power cord and air hose are neatly coiled to prevent damage.
- Fuse Check: If the unit fails to power on, check the 12V DC power outlet fuse in your vehicle and the fuse located within the inflator's power plug. Replace with a fuse of the same rating if necessary.
7. Troubleshooting
If you encounter issues with your TOPDC TD-S30L, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Inflator does not turn on. | No power from 12V outlet; Blown fuse in vehicle or inflator plug; Loose connection. | Ensure vehicle engine is running. Check vehicle's 12V outlet fuse. Check and replace the fuse in the inflator's power plug if blown. Ensure the plug is fully inserted. |
| Slow inflation or low pressure. | Air leakage; Partially blocked air hose/nozzle; Low vehicle battery voltage. | Ensure air hose is tightly screwed onto the tire valve. Check for kinks or blockages in the hose. Ensure vehicle engine is running to provide adequate power. |
| Inflator stops before reaching preset pressure. | Overheating protection activated. | Allow the inflator to cool down for 10-15 minutes before resuming operation. Avoid continuous use for extended periods. |
| Inaccurate pressure reading. | Loose connection to tire valve; Sensor issue. | Ensure the air hose is securely connected to the tire valve. Compare reading with a known accurate tire gauge. |
