Steps for usage

Question 1,
Why the tire pressure stop at 2.4 Bar (35psi) ?  My car need 2.8 bar or 3.2 bar.
B31A tire inflator have pre-set tire pressure function, the default preset pressure is 2.4 Bar.

When the pressure reach 2.4bar,it will auto-stop inflation. 

We can change the preset pressure as below step,
1.To set the target pressure, press and hold the “+”or “-” button until the LCD flashes. 
2.Continue to press “+”or”-” buttons until your target pressure is reached. 
3.The LCD will continue to flash for a few seconds and then stop automatically. 
4.This means your pressure has been set OK now. 
Question 2,
Why the tire inflation speed is not so fast?
When the compressor working, it needs 100W (12V 8A) power supply.
We suggest to start the engine of your car before you inflate the tire.
1. This will ensure that there is enough power supply.
2. This will faster the speed of tire inflation.
3. Protect your car battery.
Especially in winter,the activity of car battery decreased,the battery can not provide enough power for tire inflation.
