Or, you can secure it directly into the workbench with lag screws and flat washers. (Mounting hardware is not provided due to the many possible set ups and workbench thicknesses.) 3. Stand away from the line of rotation of the wheel, turn the grinder ON, and allow it to run for one minute. —The grinder should run smoothly. • You'll need room for potentially large workpieces. When locating your grinder, remember: —If there is an obvious problem with the way the grinder is running, turn it OFF immediately and troubleshoot the problem, using the troubleshooting table on Page 17. DO NOT operate the grinder until it is fixed. • Grinding spreads dust in the immediate vicinity of the grinder. • Grinding creates flying sparks that MUST be out of reach of any flammables. • You'll need a lot of light around the grinding wheel. -12- H7758/H7759 8" & 10" Bench Grinders SECTION 4: OPERATIONS Operation Safety Awarning Damage to your eyes, lungs, and ears could result from using this machine without proper protective gear.

In addition to the safety instructions in this manual, the most important safety consideration is to use common sense at all times. What may be okay in one situation, may not be safe in another. Here are some tips to keep in mind while grinding: • Make sure all guards are in place. • Remember that grinding often produces sparks. DO NOT allow anyone to stand in the path of the sparks. DO NOT grind near flammable materials. • Maintain proper care of your wheels. Read the Wheel Care instructions for ideas on how to do this. • Wear the proper protective clothing. Particles flying off of a grinding wheel will be traveling very fast—prepare for this. Wear safety glasses/face shield, a dust mask, earplugs, a leather apron, and heavy leather boots. • Grasp the workpiece firmly and properly support it on the tool rest during grinding. Maintain even pressure and control of the workpiece when grinding. • Concentrate on the task at hand. STOP grinding if other people are distracting you or your mind is on something else. • DO NOT grind on the side of the wheel. The wheels provided with the Model H7758/ H7759 are not designed for side grinding. H7758/H7759 8" & 10" Bench Grinders -13- Wheel Care Wheel Selection Your safety when grinding depends, on a large part, on the condition of the wheel during grinding. A wheel in poor condition presents the possibility of breaking apart during rotation and injuring the operator and possibly causing property damage. Here are some tips to help you avoid breaking the wheel: • Always transport, store and handle wheels with care. Wheels may be damaged if they are dropped or if heavy objects are stacked on them. • Select the right grinding wheel for the job. DO NOT grind material inappropriate for the wheel type. • Select the right wheel for the machine. A machine that rotates at a higher RPM than the wheel is rated for may cause the wheel to fly apart. • Mount the wheels properly. (See the Wheel Replacement instructions on Page 15 for guidance.) Never use a wheel with the wrong arbor size for the grinder. • Do not abuse the wheel by jamming the work into the grinding wheel with excessive force. • Learn how to use the grinder and the grinding wheels properly. Ask a trusted person with experience or consult with your local library to learn more. • Always spin water/coolant out of the wheel before turning the grinder OFF. This may take 5-10 minutes. (If moisture is left on the wheel, the wheel may warp.) • Do not store wheels in damp or wet locations. • Grinding on side of the wheel may cause wheel damage. • Replace wheels when the diameter becomes 2" smaller than its original size. The Model H7758 only accepts Type 1 wheels with a %" bore. The Model H7759 only accepts Type 1 wheels with a IVi" bore. Aluminum oxide and silicon carbide wheels are marked in a somewhat uniform manner by all the major manufacturers. Understanding these markings will help you understand the capabilities of various wheels. Always refer to the manufacturer’s grinding recommendations when selecting a wheel for your project. The basic format for wheel numbering is: Prefix Abrasive Type Grit Size Grade Bond Type 1 A 60 L V The Prefix is the manufacturer’s designation for a particular wheel type (eg, Type 1 wheels). ...
