1. This machine is not suitable for inflated air in large and heavy vehicle tires, such as trucks and large trucks.
2. When using, start the car engine to enhance the power and prevent power loss from the car.
3. This machine is limited to use a direct current (DC) power supply of 12V and 30A. It is not safe to use household 220V power. If you want to use household power, you must add a transformer and ensure the current is correct.
4. For car tire inflation, every 15 minutes, it is best to take a 15-minute break to allow the machine to cool slightly before using it again, which can extend the life of the motor. When inflating an inflatable boat, it can be used continuously for half an hour.
5. For general car tires, it takes about 1-3 minutes to inflate to a normal tire pressure of 36Psi (2.5kg/cm2), which may vary depending on the air pressure inside the tires. Large tires will take longer. If the air pressure starts to rise rapidly within a few seconds after starting the inflation, reaching around 70Psi (approximately 5kg/cm2), it indicates that the air is blocked and is not entering the tires. In this case, you need to immediately turn off the power, remove the air nozzle, and re-operate. Otherwise, the instrument and motor may be damaged.
6. When using this machine, do not leave the body, pay attention to the tire pressure at any time, and the air pressure cannot exceed the tire pressure standards set by the car factory or tire factory.
7. This machine should be avoided from moisture, heavy falls, and sand intrusion.
8. Do not allow children to use, to avoid unnecessary harm.

 Remove the power clamp, distinguish the positive and negative poles of the glass, and directly clamp it onto the car battery.Press the air pump switch,Can be inflated immediately.

When inflated, please start the air pump before connecting it to the tire. The instrument needle will rise with the saturation level of the tire. When the needle reaches the appropriate level, stop inflating.Tire pressure(The tire pressure for a typical sedan is36psi (/2.5kgcm2),Remove the plug and air nozzle,Completion of the work.

  Please use the professional ball needle equipped with this machine to connect the nozzle and air nozzle.,To inflate sports balls and other equipment that requires air.
