Product 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 7-10, that is, about 100PSI (instantaneous pressure)
