Operating Instructions
1. Jump Starting a Vehicle
- Ensure the VTOMAN X3 is sufficiently charged (at least 50% recommended).
- Connect the smart jumper cable to the jump start port on the VTOMAN X3.
- Attach the red clamp (+) to the positive terminal of the vehicle's battery.
- Attach the black clamp (-) to the negative terminal of the vehicle's battery.
- Once connected correctly, the smart jumper cable's indicator light will turn green. If it's red or beeping, check connections for proper polarity.
- Start the vehicle's engine.
- Once the engine starts, immediately remove the jumper cables from the vehicle battery, then disconnect from the VTOMAN X3.
The VTOMAN X3 can jump start 12V vehicles with up to 8.5L gas or 6.0L diesel engines, even in extreme temperatures (-50°F to 150°F). It also features a BOOST function for completely drained batteries.

2. Using the Air Compressor (Tire Inflator)
- Connect the pump tube to the air compressor port on the VTOMAN X3.
- Attach the other end of the pump tube to the tire valve. Ensure a secure connection.
- Press the power button to turn on the device. The digital display will show the current tire pressure.
- Use the mode button to select the desired inflation mode (SUV, Car, Bicycle, Ball, or Customizable).
- Adjust the target pressure using the '+' and '-' buttons. The display allows switching between BAR, PSI, and KPA units.
- Press the start button to begin inflation. The compressor will automatically stop once the preset pressure is reached.
- Disconnect the pump tube from the tire valve and the device.
The VTOMAN X3 features a maximum pressure of 150 PSI and an airflow of 35 L/min, capable of inflating a standard flat tire (205/55R16) from 25 PSI to 36 PSI in approximately 1 minute.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not turn on. | Battery is completely drained. | Charge the device fully before use. |
| Vehicle does not jump start. | Incorrect clamp connection (reverse polarity). Vehicle battery is severely drained (below 2V). VTOMAN X3 battery is too low. | Ensure clamps are connected to correct terminals (red to +, black to -). The smart cable will indicate errors. Use the BOOST function if available, or try charging the vehicle battery for a few minutes before attempting to jump start. Recharge the VTOMAN X3. |
| Air compressor stops or overheats. | Continuous operation for too long. | Allow the compressor to cool down for several minutes before resuming operation. |
| Tire not inflating. | Pump tube not securely connected. Target pressure set too low. | Ensure the pump tube is tightly screwed onto the tire valve. Adjust the target pressure to the desired PSI/BAR/KPA. |
