5. Operating Instructions: Jump Starting a Vehicle
The GOOLOO GP3000 is designed to safely jump start vehicles with up to 9.0L gasoline engines and 7.0L diesel engines.
Safety Precautions:
- Ensure the jump starter is adequately charged before use.
- Always connect the clamps to the correct battery terminals (red to positive, black to negative). The SUPERSAFE technology automatically detects reverse polarity to prevent damage.
- Do not crank the engine for more than 3 seconds per attempt. Wait at least 30 seconds between attempts.
- Do not leave the jump starter connected to the vehicle battery after the vehicle has started.
Jump Starting Steps:
- Connect Jumper Cables: Insert the blue plug of the heavy-duty jumper cables into the jumper cable port on the GOOLOO GP3000.
- Connect to Vehicle Battery: 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.
- Check Indicator: The indicator light on the smart jumper cable will show green if the connection is correct and the battery voltage is sufficient for a normal start. If the battery voltage is very low or there is no battery, the indicator might not show green immediately.
- Start Vehicle: Once the green light is solid (or if using BOOST mode, see below), start your vehicle.
- Remove Cables: After the vehicle starts, immediately remove the black (-) clamp from the vehicle battery, then the red (+) clamp, and finally disconnect the jumper cables from the jump starter.
Using the "BOOST" Function (for very low/dead batteries):
If your vehicle's battery voltage is extremely low (below 8V) or completely dead, the smart jumper cable might not show a green light. In this case, you can use the "BOOST" function:
- Connect the jumper cables to the jump starter and then to the vehicle battery as described above.
- Press and hold the "BOOST" button on the smart jumper cable for 3 seconds. The indicator light will turn solid green.
- Start your vehicle within 30 seconds.
- Once the vehicle starts, immediately remove the clamps in reverse order.
