Bought a new double cylinder portable air pump, used once, didn't use my car 2.5 normal tire pressure, just when the plug is around 2, and then open the pump quickly to 2.5, turn off the machine down to 2.2, and then tried down to 3, and then down 2.5, does this thing have a problem? How should I use it?
Two. Attention of portable gasoline pump1, and then use, please start the car engine, to enhance the power, do not consume the car battery power.2 、 this machine is limited to DC (DC12V, 20A) power supply and can not use domestic high voltage power supply,3, when charging, please continue to work for 10 minutes for cooling rest, can extend the life of the motor. When the rubber boat is inflated, it can work continuously for 30 minutes.4, the average tire in the inflatable, in about 3 minutes, can reach 220KPA normal tire pressure. Big tires will be longer. If the instrument begins to inflate, the instrument indicator rises rapidly, indicating that the air has not been filled into the tyre. It must stop working and re operate, otherwise the instrument and motor will be damaged.6, when using, people do not leave the body, pay attention to the tire pressure at any time, not too saturated.7, the car cigarette lighter, such as unclean and non conductive, or fuse blowing, the machine can not function properly, please ensure that cigarette lighter electrical conductivity.
3. Turn on the motor and start charging;4, inflatable, instrument pointer began to rise with the pressure, the big pointer to the appropriate tire pressure when the car (general car tire pressure is 30-40PSI), turn off the inflator switch, remove the plug and gas nozzle.5, please use the machine equipped with professional ball needle, mouth and air mouth connected, for ball games, and other gas equipment inflatable.
I. usage of portable tire inflator pumps1, the rubber hose top valve directly inserted in the tire valve, hear the tire deflated sound, that the air has been circulating, tighten the steam knob.2, remove the power clip, red clip the battery positive, black clip battery negative, or insert directly into the cigar lighter to electrify;
