Start with no more than 1/8 of a turn. Turn the adjustment screw clockwise to slow the door closer down, counter-clockwise to speed it up, then get down off the ladder and observe the effect. Open the door and watch it close. If it closes right the first time, check it 10 more times.
How do you lubricate a hydraulic door closer?
Hinges and door closers should get a few drops of penetrating oil at the top so it runs down into the wearing surface between the pin and the housing. Lock mechanisms that need lubricant should get a shot of dry graphite from a spout-type bottle.
Can door closers be repaired?
If the problem is a damaged arm or adjusting screw which can be repaired, then do that. If the door closer does not respond to therapy (the appropriate adjustments), it is likely internally damage and needs to be replaced.
How long do door closers last?

Why does my screen door not close all the way?
Screen doors fail to close properly when their hinges become imbalanced as a result of your home shifting or if the door frame has swelled or become loose. Swelling paint also can be a factor. The longer you go without correcting the situation, the greater the potential for permanent damage to the door or frame.
