- Connect Clamps to Vehicle Battery:
- 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.
- Initiate Jump Start: Once connected correctly, the jump starter is ready. If the vehicle battery is extremely low (below 0V), press the "BOOST" button on the jump starter to force a restart.
- Start the Vehicle: Turn the vehicle's ignition key to start the engine. If the engine does not start immediately, wait 30 seconds before attempting again. Do not crank for more than 3 seconds per attempt.
- Disconnect Clamps: Once the vehicle starts, immediately disconnect the black (-) clamp from the vehicle battery, followed by the red (+) clamp. Then, disconnect the jumper cable plug from the jump starter unit.
Allow the vehicle's engine to run for a few minutes to recharge its battery.
