How to preserve the foam if it still remains in the cylinder?

It often happens that all the foam is not used in the work, and it is a pity to throw away an almost full cylinder. How to save it correctly? One condition is necessary that the adjustment screw is tightly closed.

It is necessary to store foam in an upright position. Do not store the cylinder in a hot room or near a heat source. If not all of the foam is used, then you should not unscrew the gun. It serves as a stub.

In this form, it can be stored. And when you want to use it, you simply peel off the foam from the end of the gun nose and remove a little inside. Now you can use it again. After work, put the foam cylinder upright again and it can stand up to a total of 10 months.

What happens if the gun is unscrewed from the cylinder?

If you need to unscrew the pistol, in which the contents still remain, then you need to let the cylinder settle vertically for several hours. Immediately not recommended to shoot. The rest will drain to the bottom, and only compressed gas will remain on top. Before shooting, do not shake.
