Easing the wear on a Hamilton Beach bread machine

Baking 2 pound loaves of wheat bread, I finally discovered a way after years of using a bread machine to ease the wear of its operation. It typically skips gears, making loud noices, because the dough is thick and rough on the kneading appendage. I learned to put the last half cup of wheat flour after its mixing the first four cups of wheat flour with ease about five minutes into its routine.
