Locate the adjustment screw on the end of the screen door closer. It is an inset screw on the side of the closer nearest the hinges on the door. This is the bypass valve portion of the closer.
Open the door fully and prop it open with a broom or hold it open with one hand. Opening the door gives more room to reach the door closer for adjustments.
Place a Phillips screwdriver in the inset and turn the screw in the bypass valve 180 degrees clockwise. The clockwise adjustment will allow the door to close more softly and slowly.
Release the door and observe the closing action. If it is now closing too slowly and not fully catching in the latch, it will need adjusting in the other direction.
Turn the adjustment screw 90 degrees counterclockwise to increase the door-closing speed and force. Release the door again and observe its actions.
Turn the adjustment screw in either direction 45 degrees to make smaller incremental adjustments at a time until the door operates properly by closing fully, latching and not banging on the latch.
