How do I use the jump starter to start a vehicle?

Turn off the vehicle ignition and accessories. Plug the Boost Cables Connector into the Clamp Connection Slot on the back of the unit. Connect the red clamp first to the battery's positive terminal, then connect the black clamp to the chassis or a solid metal vehicle component (not directly to the negative terminal). Turn on the ignition and crank the engine in 5-6 second bursts until it starts. Disconnect the negative clamp first, then the positive clamp. (Page 8)
