Includes regulator + 2 spare cylinders
Compatible with Schrader and Presta style (by replacing the rubber gasket with the nozzle) )
The default setting is compatible with Schrader valves. For Presta ceremony, please replace the washer in the opposite direction.
If the mouth of the gasket is tight, please use pliers and remove it.
You can also use it with the default setting alone, but in such cases, please push the valve deep into it. Otherwise, the inside gasket may be squeezed out.
Note:
Please make sure the valve on the tube is open before use. If the valve on the tube is closed, the pressure inside the head becomes high pressure, and the needle will cut out into the cylinder and prevent use.
