Operating Instructions
Jump Starting a Vehicle
- Prepare the Vehicle: Turn off the vehicle's ignition and all accessories (headlights, radio, air conditioning). Engage the parking brake.
- Connect Clamps to Jump Starter: Insert the smart clamp connector firmly into the jump starter's 12V output port. Ensure a secure connection.
- Connect Clamps to Battery:
- Connect the RED (+) positive clamp to the vehicle battery's positive (+) terminal.
- Connect the BLACK (-) negative clamp to the vehicle battery's negative (-) terminal or a solid, unpainted metal part of the vehicle chassis away from the battery.
The smart clamp indicator light will show the connection status. A solid green light indicates a correct connection and readiness to jump-start.
- Start the Vehicle: Once the smart clamp indicator is green, start the vehicle's ignition. If the vehicle does not start immediately, wait 30 seconds before trying again. Do not crank for more than 3 seconds per attempt.
- Disconnect Clamps: Once the vehicle starts, immediately disconnect the BLACK (-) negative clamp first, then the RED (+) positive clamp from the vehicle battery. Finally, disconnect the smart clamp connector from the jump starter.
