Not strictly a home repair question but I have nowhere else to go.
Where can I find an exploded diagram of how thse things work: backswing, speed of closure and so forth?
The closer here has one visible adjustment for speed in the end of the cylinder.
Also at the end of the cylinder are 3 equal spaced indents which look like sockets for some custom tool.
I know how the screw works to adjust the speed.
1.) How is the back swing adjusted?2.) Are there separate adjustments at each end of the cylinder? The cylinder has those 3 indents at both ends.
any leads to manuals pdfs on such devices would help.
I'm going to make a simple makeshift tool of a stick of wood and 3 screws from a tracing of the end of the cylinder. But I still need to know what to do with it.
