How do you adjust door closer 320g?

To adjust a 320G door closer, first locate the adjustment screws, usually found on the body of the closer. For closing speed, turn the larger screw; clockwise slows the closing speed, while counterclockwise speeds it up. To adjust the latching speed, use the smaller screw, following the same direction guidelines. Always make small adjustments and test the door's operation after each change to achieve the desired performance.
