How do I remove the loaf from the pan after baking?

How do I remove the loaf from the pan after baking? The first two inches from the bottom seems to stick to the pan. I usually place all the ingredients in the pan in the evening and set it to be baked in the morning. Is this the problem? I have to tap it very hard on a surface to loosen the loaf. I am afraid to use any oil or shortening on the pan. It is a West Bend breadmaker model # 41040.
