Setting advice
Tip: Open the door fully and tighten both adjusting screws on the door closer.
If this is done correctly, the door will stay open and not close.
Then slowly turn the appropriate adjustment screw so that the door closes quietly.
This determines the overall closing speed.
If the door does not close completely, slowly turn the other adjusting screw to adjust the speed at which the door closes.
This way you can adjust the entire closing speed to your own preference.
