8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not turn on. | Low battery or no charge. | Charge the jump starter fully. |
| Vehicle does not start after connecting. | Incorrect clamp connection, severely dead battery, or vehicle issue. | Ensure clamps are connected correctly (red to +, black to -). Check if the smart clamp indicator is green. If the battery is extremely dead, it might require more attempts or professional assistance. Consult a mechanic if the vehicle still doesn't start. |
| Air compressor not inflating. | Air tube not securely connected, wrong nozzle, or target pressure not set. | Ensure the air tube is tightly screwed in. Verify the correct nozzle is used and securely attached. Set the desired pressure on the display. |
| Smart clamp indicator not green. | Incorrect connection or safety protection activated. | Check all connections. If safety protection is active (e.g., reverse polarity), disconnect and reconnect correctly. |
