Remove the cigarette plug and insert it directly into the cigarette lighter in your car until the pump starts. The nozzle on the top of the inflatable hose is directly inserted into the tire valve. The air is discharged from the nozzle into the tyre tire indicating that the air is flowing, and the small-wrench is tightened 90 degrees inward. When inflated, there is no air leak. When inflated, the hand pointer of the instrument increases with the saturation of the tire. When the pointer reaches the proper tire pressure, remove the plug and nozzle .
