It’s because your door closer has a hold open, look on the instructions of there are any adjustments on the arm, otherwise your closer would be internal hold open and the only way to make the closer hold open further is the remount the door closer body and shoe closer to the hinge.

Tension ? What UTTER Bollocks. Those two screws (there) at 5:58 do absolutely NOTHING for spring tension. All they "DO" - is alter the needle-nozzle openings in the oil-ways, to allow a quicker or SLOWER movement of oil from the pistons inside the unit - to enable the user to choose the speed the oil is allowed to PASS these two adjuster screws, so that you either have a SLOW door sweep (closing) action &/or a door LATCHING speed. They do absolutely nothing other than open or close off, an oilway.

Sorry, the arm should not look that way and that product is ultra cheap rubish. If you want a door closer, buy a Tjss, Geze or Dorma and let it install by a pro. One leg of the arm - depends on the brand and product - ALWAYS stands in a 90 degree angle to the door / frame. Otherwise the closer don‘t work how he should because the adjustements don‘t react on the same point. Better: don‘t install it self. There are too many models for too many specific door situations. (Mounted on the side against the hinches, mounted on wide or thick or both doors, mounted in the steelframe.....) A course for pro‘s at one of the market leaders takes a full day. For a not pro, it is not possible, to find the right closer type for a specific door.
