I have collected this information for many years and have found the information they contain to be priceless in using and setting up the machines properly. I believe this manual will be a valuable resource of knowledge that will provide a lot of helpful information that is often hard to find. My manuals are not photocopies. I maintain a high standard of quality in my reproductions. Most of the manuals I reproduce look better than their originals. I have professionally digitally edited every page, and removed stains, wrinkles and handwriting. All of the manuals are printed on thick white paper to withstand shop wear and tear; they are then comb bound with heavy cover pages so they lie flat on the workbench.
