5. Operating Instructions
Jump Starting a Vehicle
- Ensure the jump starter has sufficient charge (above 50% recommended).
- Connect the red (+) clamp to the positive (+) terminal of the vehicle's battery.
- Connect the black (-) clamp to the negative (-) terminal of the vehicle's battery.
- Observe the LED intelligent display on the smart clamps. It should show a stable voltage. If any error indicators appear, refer to the Troubleshooting section.
- Start your vehicle's engine. If it doesn't start immediately, wait 30 seconds before trying again. Do not attempt more than 3 consecutive starts.
- Once the engine starts, immediately remove the smart clamps from the vehicle battery, first the black (-) clamp, then the red (+) clamp.
- Disconnect the smart clamps from the jump starter.
Important: Do not leave the clamps connected to the vehicle battery for extended periods after starting the engine.
