Usage: 1. Take out the cigarette lighter plug and plug it directly into the car cigarette lighter. Start the car and turn on the air pump switch. After the air pump starts, insert the air nozzle at the top of the inflatable hose directly into the tire valve. When you hear the sound of air leaking from the tire, it means that the air has been circulated. You can tighten the air nozzle to inflate it. At this time, the air will no longer leak out. 2. When inflating, the pointer of the instrument increases with the saturation degree of the tire. When the pointer reaches the appropriate tire pressure (the tire pressure of the general car tire is 2.0KG/CM-2.6KG/CM), take out the plug and gas nozzle, that is, finish the work.

Please connect (tighten) with the professional ball needle and nozzle provided by this machine to inflate the ball and other inflatable equipment.

If you want to test the arrival, you can first release half of the tire pressure, or start the air pump first, then slowly get the tire and screw it to the air nozzle!

Precautions and usage:
1. When you use it, please start the car engine first to enhance the power without consuming the power of the car battery.
2. This machine is limited to DC (DC12V 20A) power supply. Household high-voltage power supply is not allowed. If household high-voltage power supply is used, transformer is required.
3. When inflating, please work continuously for 10 minutes for cooling rest, which can prolong the service life of the motor. Rubber raft when inflated, it can work continuously for 30 minutes
4. Generally, when the tire is inflated, it can reach 220KPA normal tire pressure in about 3 minutes. Big tires will take a little longer. For example, when inflation starts, the pointer of the instrument rises rapidly, which means that the air is not filled into the tire and must stop working and operate again. Otherwise, the instrument and motor will be damaged.
6. When using, people should not leave the body, pay attention to tire pressure at any time, and should not be too saturated.
7. If the car cigarette lighter is not clean and conductive, or fuse blown, the machine cannot operate normally, please make sure that the cigarette lighter is conductive well.
8. This machine should avoid moisture, heavy fall and sand intrusion, and avoid children playing with it to avoid damage.
9. The starting current of the machine is very large. Do not turn on the power switch when the tire is connected. Otherwise, the fuse of the car may be burnt out due to excessive starting current. The correct operation is to turn on the power first, and then connect the tire to inflate after the air pump starts to work normally. If you need to restart after turning off the power supply during operation, you should also unscrew the air nozzle and start it again, otherwise it may burn out the fuse of the car.
Note: Some air pumps are barometer nominal 300PSI, just to attract attention. Actually, it is impossible to reach such a high pressure (20 atmospheric pressure). Generally, the tire pressure is about 2.3 pressures, about 35PSI, generally, the maximum air pressure that the air pump can reach is 7 to 10, that is, about 100PSI.
Usage:
1. Insert the top valve of the rubber hose directly into the tire valve. When the tire is exhausted, it means that the air has been circulated. Tighten the steam filling knob..
2. Take out the power clip, clamp the positive electrode of the battery in red, clamp the negative electrode of the battery in black, or insert cigarette lighter directly to power on;
3. Turn on the motor to start inflation;
4. When inflating, the gauge pointer starts to rise with the air pressure. When the large pointer reaches the appropriate tire pressure of the car (generally, the tire pressure of the 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 provided by this machine to connect with the air nozzle to inflate the ball and other required air equipment.
