How do I level my Kenmore dryer during installation?

Check the levelness of the dryer by placing a level on top of the dryer, first side-to-side, then front-to-back. If the dryer is not level, prop it up using two stacked cardboard corner posts and use a wrench to adjust the legs up or down. It may be necessary to level the dryer again after it is moved into its final position. (Page 13)
