If you have gotten home and now can't remember how to turn your screws. Don't worry, take a good look at your appliance. Each screw has an arrow pointing the direction you need to turn the key. Place your key in the hole closest to the tail end of the arrow and move the key like a lever toward the point of the arrow, once you have made a complete turn slide the key out and try your appliance back in.
If you have more than one screw pay attention to the screws as you turn them so you only turn each screw once.
