Thank you so much for explaining it so easy. I watched the company instruction video first but no words there, so it was not enough. Now I can fix the main entrance door in our building, and thanks to you, now I know where to tighten exactly.

In the hallway of my mother's apartment building there is a door with such a door closer. They are terribly hard to open, they are very heavy. Can it be changed? She is an older woman and she has a problem.
