How do I adjust the rollers on my refrigerator to ensure proper door closure?

Remove the base grille by grasping it at the bottom and pulling it out. Turn the roller adjusting screws clockwise to raise the refrigerator or counterclockwise to lower it, using an adjustable wrench (3/8" hex head bolt) or pliers. For proper door closure, the bottom front edge of the cabinet should be approximately 5/8" from the floor. To replace the base grille, align the prongs on the back of the grille with the clamps in the cabinet and push forward until the grille snaps into place. (Page 4)
