【Product Description】:
1, This machine is suitable for all 12V car tires, especially for 4x4, midibus, trucks with a capacity of less than 2 tons, and high-end sedans, etc., with large air volume and fast air filling.
2, also suitable for motorcycles, bicycles, ball games, inflatable toys, beach floats, etc.
3, on highways, in the wilderness or early in the morning on the way to work, a sudden flat tire or puncture can be more effective for emergency use.
4, Maintaining the correct tire pressure for your car can ensure safety on the road and save on gas. Always carry a spare tire with you just in case, as it can be very useful in an emergency.
5, equipped with a complete set of air nozzles, which can be used to inflate tires, rubber boats, air mattresses, inflatable toys, ball-type inflatables, and other various applications.

【Usage Method】：
1. Insert the air nozzle at the end of the rubber hose directly into the tire valve, and when you hear the sound of air escaping from the tire, it indicates that the air is flowing. Continue to tighten the air nozzle, and at this point, the air will no longer escape.
2. Remove the battery clamp (without the cigarette lighter plug) and directly clamp it to the positive and negative terminals of the battery. Avoid short-circuiting by touching the wires. Turn on the switch, and the air can be inflated. (The dual cylinder air pump has a large power, so it cannot be directly plugged into the cigarette lighter through the converter, which may easily damage the car's cigarette lighter and wiring.)
3. When inflated, the instrument pointer rises with the saturation level of the tire. When the pointer reaches the appropriate tire pressure (generally for passenger car tires, the pressure is 223kpa = 35PSI), remove the plug and air nozzle, and the job is complete.
4. Please connect the professional ball needle and plastic nozzle provided with this machine to the air nozzle, to inflate sports balls and other equipment that require air.

【注意事项】：
1. Not for use in the air pressure of large and overweight vehicle tires, such as trucks, large trucks, and box-type semi-trailers, etc.
2. When using, please start the car engine to enhance power supply, without consuming the car battery power;
3. This machine is limited to use a direct current (DC12V10A) power supply and cannot be used with household high-voltage AC (AC220V) power;
4. When inflated, please stop the machine for 10 minutes after continuous operation for 10 minutes to cool down to prevent damage to the air pump and accessories, and to extend the life of the motor. For inflatable rubber boats, you can operate continuously for 30 minutes.
5. When inflating a general tire, it usually takes about 3-5 minutes to reach a normal tire pressure of 30PSI, and larger tires will take longer. If the gauge's needle rapidly rises to 50-100PSI when you start to inflate, it indicates that the air is blocked and is not entering the tire. In this case, you need to immediately disconnect the air nozzle and restart the operation, otherwise the motor and the gauge are prone to damage.
6. Do not leave the machine when using it, and always pay attention to the tire pressure, which should not be too saturated.
7. After using this machine, the air nozzle wrench must be straightened to prevent the rubber inside from fatigue.
8. This air pump has an integrated fuse in the plug. If the air pump does not start, please open the plug to check and replace the fuse (the fuse is 15A).
9. This machine should be avoided from moisture, heavy falls, and sand and mud intrusion. It should not be played by children to prevent damage;
10. The pressure required for each type of tire is different. Please refer to the markings on the side of your car tires or consult the car manufacturer.
