AIR COMPRESSOR (please read the manual before using the air pump) Instructions for use: 1. Put the cigarette plug of the air pump into DC12V socket in the car. 2. Then screw the air nozzle onto the tyre valve tightly, otherwise the air will not flow into the tyre. 3. When inflating the tyre, please pay attention to the pointer of the gauge which can rise up as the pressure inside the tyre rises. Normally, two or three minutes are enough to make tyre reach rated air pressure 206Kpa, (0.206Mpa), the time of infl ation for a small truck may be a little longer. 4. While reaching rated air pressure, turn off the switch, take off nozzles and plug and the inflation is complete.
