To quickly assess the difficulty of the text, read a short excerpt:
If excessively hot, use a small quantity of fine plum- bago mixed with oil, and cool off with cold water or ice. When the machine is stopped, remove the pillow block, and clean and scrape the bearing. The commutator must always present a clean, polished surface free from scratches. If accidentally scratched, the commutator can be polished with very fine sandpaper, moistened with a drop of oil. Never use emery paper or cloth. The commutator is in its best condition when it presents a rather dark... glazed surface. The commutator must never be allowed to have flat spots; always keep its circumference perfectly true. Do not attempt to oil or fit while running with current on, or brushes in operation. The brushes must always be firmly fastened in the holders, and must be so adjusted, when the armature is not running, that they rest on the commutator at exactly diametrically opposite points; the bevel end of the brush must conform accurately to the curve of the cummutator. The brush-holder should be occasionally moved laterly to allow brushes to wear the com- mutator evenly.
