How to use the car tire air pump?

Too low or too high tire pressure will affect the normal use of the car. Therefore, once the tire pressure is found to be insufficient, it is necessary to inflate the tire as soon as possible, but I just don't know how to operate it. Here's how to use the tire inflator.

First, turn on the power switch. At this time, the LED light will light up, and the air pump of the vehicle will be in standby state.

Then, press the addition and subtraction keys to preset the normal range of tire pressure. After adjustment, the value set by the user will appear on the display screen.

Then, fix the inflation valve of the vehicle, then pull out the inflation tube, install the top chuck on the inflation valve, and press down the chuck fixing bolt.

Finally, turn on the inflation switch, and the air pump begins to inflate the tire. During inflation, if the tire pressure is within the normal range, you can press the stop button.

It should be noted that the car should be kept still for a period of time before the tire is inflated, and then inflated after the tire is completely cooled, otherwise the tire will heat up when driving, and the air pressure in the tire will also increase, so inflation at this time will affect the inflation accuracy.
