Features: This machine is suitable for inflating cars, bicycle tires, balls, rubber boats, etc., and has a wide range of applications. With this product, car tires can maintain the correct tire pressure at any time, save gasoline, protect tires, and ensure driving safety. 2. Purpose: Insert the nozzle on the top of the rubber tube directly into the tire valve. When you hear the sound of a flat tire, it means that the air has circulated. The nozzle wrench can be pressed 90 degrees inward without air leakage. Take out the plug and place it directly on the car cigarette ignition to inflate it. When inflating, the gauge pointer rises as the tire saturates. When the pointer reaches the proper tire pressure (car tire pressure is 223kpa=35PSI), pull out the plug and nozzle, and the work is complete. Please use the professional ball needle and plastic nozzle equipped with this machine to connect with the air nozzle. Package Includes: 1 x Car Air Pump 3 x Air Nozzle
