Open the attic stairs and climb up so you can see the springs. Find the hook or eye bolt securing one end of the attic spring to the metal stair arm on each side of the stairs.
Turn on the light in the attic or take a flashlight with you. Climb into the attic and sit or stand to one side of the attic stair opening. Ask a helper to close the attic stairs. This will bring the springs to a relaxed position for adjustment.
Rotate the nut securing the hook or eye bolt counterclockwise with a wrench to decrease the spring tension. If it is necessary to increase the tension, turn the nut clockwise. Do not turn the nut clockwise more than three full turns.
Repeat for the spring on the opposite side, turning the nut the same number of turns as the previous nut. Stand to the side of the attic stair opening, and ask your helper to open the stairs.
Climb down and test the opening and closing of the attic stairs. If the stairs still do not operate correctly, consider purchasing and installing a new set of springs.
