Description Multifunctional four-in-one inflatable vacuum cleaner: Can be inflated/vacuumed/measured tire pressure/lighting; (Product parameters): Product Voltage: 11.1-12 V Product Pressure: 150PSI Product Configuration: 1 host 1 instruction Chinese and English air nozzle suction nozzle extension tube; (Product Description): 1. This machine is suitable for car tires, especially 4x4, medium buses, trucks under 2 tons, cars and other larger tires, with large air volume and fast inflation. 2. Also suitable for motorcycles, bicycles, ball games, rubber boats, floating beach beds, inflatable toys and so on. 3. On the highway, in the wild or at work in the morning, the tire suddenly leaks or the tire is injected, which can be used to provide first aid. 4. Maintaining proper pressure in car tires can ensure driving safety and save gasoline. 5. Equipped with a complete set of inflatable nozzles that can be used to inflate tires, rubber boats, airbags, inflatable toys, balls and many other purposes. (Instructions): 1. Insert the air nozzle on the top of the rubber inner tube directly into the tire valve. When you hear the sound of air leaking out of the tire, it means that the air was circulating. Continue tightening the air nozzle and the air will no longer leak. 2. Connect the power supply to a 220 V outlet 3. When pumping, the meter hand rises with the saturation of opony.Gdy the hand will reach the appropriate tire pressure (the overall pressure in car tires is 223kpa=35PSI), remove the stopper and air nozzle to complete the work. 4. Use a professional ball needle and plastic nozzle equipped with this device to connect to the air nozzle to inflate the balls and other equipment requiring air. (Precautions): 1. AC products are strictly prohibited before entering the water; 2. It is forbidden to touch children at work. 3. This device is limited to power (AC220V); 4. When pumping, stop for 10 minutes after continuous operation for 10 minutes to prevent damage to the air pump and accessories and prolong the life of the engine. 5. When the overall tire is inflated, it can reach the normal tire pressure of 30PSI in about 3-5 minutes, and the large tire will take a little more; if the meter gauge rises sharply to 50-100PSI, when you start to inflate, it means that the air is blocked, the air does not get into the tire. At this point, you should immediately disconnect the air nozzle connector and restart, 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 not be too saturated; 7. After using the machine, the air nozzle wrench should be straightened to avoid fatigue of rubber elasticity inside; 8. 9. The machine should avoid moisture, heavy fall and sand and mud infestation, and avoid children playing with it to avoid damage; 10. The pressure required for each tire is different, please refer to the label on the side of the car tire or ask the car manufacturer
