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

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