When connecting the nozzle head of the pump and the nozzle of the tire, it must be inserted vertically from above. If it is inserted at an angle, it may cause damage to the nozzle, especially the French valve.

Remove the nozzle head correctly

When the nozzle head is to be removed after inflation, it is best to use both hands to assist with one hand and push with one hand at the same time. This will not only easily remove the nozzle head, but also avoid the damage of the nozzle valve due to the angle skew when removing the nozzle head.
