[Usage]]:
1. Insert the air nozzle at the top of the rubber 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. Continue to tighten the air nozzle. At this time, the air will no longer leak out.
2. Take out the power cord battery clip (without cigarette lighter plug) and directly clip it to the positive and negative level 2 of the battery. Do not touch the line and short circuit. Turn on the switch to inflate. (The power of the double cylinder air pump is large, and the power cannot be directly plugged into the cigarette lighter through the converter, which is easy to burn out the car cigarette lighter and the line)
3. When inflating, the pointer of the instrument increases with the saturation degree of the tire. When the pointer reaches the appropriate tire pressure (generally, the tire pressure of the car tire is 223kpa = 35PSI ), take out the plug and air nozzle, and then finish the work.
4. Please use the professional ball needle and plastic nozzle provided by this machine to connect with the air nozzle to inflate the ball and other required air equipment.

[Precautions]]:
1. Do not inflate tires on large and overweight vehicles, such as trucks, trucks, box-type containerized vehicles, etc;
2. When using, please start the car engine to enhance the power, without consuming the power of the car battery;
3. This machine is limited to DC (DC12V10A) power supply, and household high voltage AC (AC220V) power supply is not allowed;
4. When inflating, please stop for 10 minutes after working continuously for 10 minutes for cooling to prevent damage to the air pump and accessories and prolong the service life of the motor. When rubber raft is inflated, it can work continuously for 30 minutes;
5. Generally, when the tire is inflated, it can reach the normal tire pressure of 30PSI in about 3-5 minutes, while the large tire will take a little longer; For example, when the inflation starts, the pointer of the instrument quickly rises to 50-100psi, it means that the air is blocked and the air does not enter the tire. At this time, the air nozzle connector should be pulled out immediately and operated again, otherwise the motor and instrument will be easily 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. After the machine is used, the air nozzle wrench must be straight to avoid fatigue of rubber elasticity inside;
8. Fuse is installed in the plug of this air pump. If the air pump does not start, please open the plug to check and replace it (fuse is 15A);
9. This machine should avoid moisture, heavy fall and sand intrusion, and avoid children playing with it to avoid damage;
10. The pressure required for each tire is different. Please refer to the mark on the side of the car tire or ask the car manufacturer.
