How do I level the refrigerator if one side is lower than the other?

Open the freezer drawer and remove the lower basket, then remove the cover leg front by unscrewing two Phillips screws and lifting the bottom out. Insert a flat-blade screwdriver into the notch on the control lever and turn it counterclockwise to raise that side, or clockwise to lower it. Both control levers must be touching the floor at all times to prevent tipping and possible personal injury or property damage. (Page 8)
