This is a reproduction, not a photocopy, of an original Harig 612 & 618 Automatic Surface Grinder Instructions and Parts Manual. There is no difference between the regular Harig Automatic and the Harig Automatic II. This manual will cover either surface grinder. We also have the manual for the Harig Autostep III.
This manual contains information on lubrication, maintenance, adjustments, operations, and controls. It also contains clear easy to read cross-sectional diagrams of all the parts of the machine. Please read contents below.

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.
