5. Operating Instructions: Jump Starting a Vehicle
Follow these steps carefully to safely jump start a vehicle:
- Prepare the Vehicle: Ensure the vehicle's ignition is off and all accessories (lights, radio, etc.) are turned off. Engage the parking brake.
- Connect Positive Clamp: Connect the red (positive, +) clamp of the JNC660 to the positive terminal of the vehicle's discharged battery. Ensure a solid connection.
- Connect Negative Clamp: Connect the black (negative, -) clamp of the JNC660 to a clean, unpainted metal part of the vehicle's chassis or engine block, away from the battery and fuel lines. Do NOT connect directly to the negative terminal of the discharged battery unless specified by the vehicle manufacturer.
- Start the Vehicle: Once both clamps are securely connected, attempt to start the vehicle. Crank the engine for no more than 5-6 seconds. If the vehicle does not start, wait at least 3 minutes before attempting again.
- Disconnect Clamps: Once the vehicle starts, disconnect the black (negative) clamp first, then disconnect the red (positive) clamp.
- Recharge the JNC660: Immediately recharge your JNC660 after each use to ensure it's ready for the next emergency.
Caution: Do not allow the red and black clamps to touch each other once connected to the JNC660. This can cause sparks and damage the unit.
