                   The main unit, American air hose, and air hose attachment port may become hot, but please rest assured that this product is equipped with a safety device that will automatically turn off the power before overheating.

                      English air pressure is not displayed.
                    
                    
                  
                  Due to the structure of the British valve to prevent air leakage, the air pressure will not be displayed just by connecting it.
 With a smart pump, when the air coming out of the air hose enters the tire tube, a pushing force is created by the air pressure inside the tire tube.
 The system works by measuring the air pressure inside the tire that is being pushed back.
 Therefore, measurements can only be taken while air is being injected .
