Q3 Attention when you use


Never remove the push rod off the tool in any case, otherwise it will cause failure of spheres locating which makes the gun fail to work.

In case of that residual material left on the push rod, please clean it up thoroughly before pulling the rod to the backward position. The purpose is to prevent the material from entering the inner mechanism and keeping the tool in good condition.
