How to use a metal tire pump

How to use a metal tire air pump is as follows:

First, insert the valve nozzle at the top of the rubber hose directly into the valve of the tire. When you hear the sound of the tire deflation, it means that the air has begun to flow. At this time, tighten the inflation knob to ensure a firm connection.

Next, take out the power clip and plug it directly into the cigarette lighter to power it on. Make sure that the power supply is stably connected to ensure the normal operation of the air pump.

Then, turn on the motor, and the air pump starts to work and inflate the tire. During the inflation process, the instrument pointer will move as the air pressure rises.

When the large pointer reaches the appropriate tire pressure for the car, the inflator switch should be turned off immediately to prevent over-inflation. Then, remove the plug and the air nozzle to complete the inflation.

The tire air pump, also known as an inflator, air pump, or car air pump, works by running the internal motor. When the air is pumped out, the valve of the communicating vessel is opened by the atmospheric pressure, and the gas enters the cylinder; when the tire is inflated, the valve is closed by the air pressure in the cylinder, and the gas enters the tire.

Through the above steps, you can easily complete tire inflation and ensure the safety of your car.
