In the video, a man is using a red tire pump to inflate a car tire. He starts by turning on the pump and then proceeds to attach the hose to the tire. The man then checks the pressure gauge on the pump to ensure that the tire is being inflated properly. Throughout the video, the man is focused on the task at hand, carefully monitoring the pressure and ensuring that the tire is inflated to the correct level. The video provides a clear demonstration of how to use a tire pump and emphasizes the importance of checking the pressure gauge to avoid over-inflating or under-inflating the tire.
