Site Considerations Children and visitors may be seriously injured if unsupervised. Lock all entrances to the shop when you are away. DO NOT allow unsupervised children or visitors in your shop at any time! Bench Load Refer to the Machine Data Sheet for the weight and footprint specifications of your machine. Some workbenches may require additional reinforcement to support both the machine and the workpiece.
PAGE 17
Tool Rest and Eye Shield The strongest mounting option is a "Through Mount" where holes are drilled all the way through the workbench, and hex bolts, washers, and hex nuts are used to secure the grinder to the workbench. The tool rest supports the workpiece during grinding. Certain types of grinding may require jigs or accessories to assure the proper angle of the workpiece against the wheel. �� Figure 7.

Wheel Care Wheel Selection Your safety when grinding depends, in 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. The Model H8148 only accepts Type 1 wheels with a 1⁄ 2" bore. The Model H8149 only accepts Type 1 wheels with a 5 ⁄ 8" bore. The Model H8150 only accepts Type 1 wheels with a 1" bore.

Wheel Inspection Do not assume that a wheel is in sound condition just because it is new—often damage can occur in shipping, with age, or with exposure to moisture. Inspect every wheel for damage. First, do a Visual Inspection. Look for any cracks, chips, nicks or dents in the surface of the wheel. If you see any of these, DO NOT use the wheel. Second, do a Ring Test. This test will give you an indication of any internal damage that may not be obvious during a visual inspection. To perform a Ring Test: 1.

4. Remove the outer wheel flange and the paper disc. Pull the wheel free from the arbor, but leave the paper disc and a wheel flange on the other side of the wheel. NEVER assemble a grinding wheel on the arbor without paper or fiber discs between the wheel and the flange. Omitting the discs can put uneven stress on the wheel, causing it to crack and possibly fly apart. ALWAYS “ring test” a wheel before assembly to make certain it has no cracks or flaws. 5.
