How to use electric air pump
1. How to use the portable tire inflator
1. Insert the top valve of the rubber hose directly into the tire valve. When you hear the tire flattening sound, it means that the air has circulated. Tighten the steam charging knob.
2. Take out the power supply clamp, clamp the positive pole of the battery in red, and clamp the negative pole of the battery in black, or directly insert the cigarette lighter to power on;
3. Turn on the motor and start to inflate;
4. When inflating, the indicator pointer begins to rise with the air pressure, and when the large pointer reaches the appropriate tire pressure of the car (generally, the tire pressure of a car is 30-40PSI), turn off the inflator switch and take out the plug and air nozzle.
5. Please use the professional ball needle and nozzle of this machine to connect with the air nozzle to inflate the ball and other air-demanding equipment.
2. Precautions for portable car air pump
1. When it is used, please start the car engine first to increase the power and not consume the battery power of the car.
2. This machine is limited to DC (DC12V 20A) power supply, and household high-voltage power supply is not allowed.
3. When inflating, please cool down and rest for 10 minutes of continuous work to extend the life of the motor. When the rubber boat is inflated, it can work continuously for 30 minutes.
4. Normal tire pressure can reach 220KPA in about 3 minutes when inflated. Big tires will take a little longer. For example, when the inflation starts, the pointer of the instrument rises rapidly, which means that the air has not been filled into the tire. You must stop working and re-operate, otherwise the instrument and motor will be damaged.
6. When using, don't leave the body, pay attention to the tire pressure at any time, and don't oversaturate it.
7. If the car cigarette lighter is not clean and does not conduct electricity, or the fuse is blown, the machine cannot operate normally, please ensure that the cigarette lighter conducts well.
8. The machine should be protected from dampness, heavy falls and sand and mud intrusion, and children should be prevented from playing with it to avoid damage.
9. The starting current of this machine is very large, please do not turn on the power switch when the tire is connected, otherwise the car fuse may be burnt out due to the excessive starting current. The correct operation is to turn on the power first, and then connect the tires to inflate after the air pump starts to work normally. If you need to restart the machine after turning off the power during operation, you should also unscrew the gas nozzle and restart the machine, otherwise the car's fuse may be burned.
