- Connect the Cables:
- Plug the smart jumper cable connector firmly into the jump start port on the GREPRO unit.
- Connect the RED clamp to the POSITIVE (+) terminal of the dead vehicle battery.
- Connect the BLACK clamp to a clean, unpainted metal part of the vehicle's engine block or chassis (a ground point), away from the battery and fuel lines.
- Initiate Jump Start:
- Ensure the cable connections are secure and correct.
- Press the BOOST button on the smart jumper cable handle.
- The cable's indicator should light up, confirming it is ready.
- Start the Vehicle: Get into the vehicle and attempt to start the engine as normal. It should start within a few seconds.
- Disconnect the Cables: Once the vehicle is running:
- Press the BOOST button again to turn off the cable.
- Remove the BLACK clamp from the vehicle's ground point.
- Remove the RED clamp from the battery's positive terminal.
- Unplug the cable from the GREPRO unit.
- Allow the vehicle to run to recharge its own battery. Recharge the GREPRO jump starter at your earliest convenience.
