SECTION 6: MAINTENANCE

Wheel Dressing

After a large number of sharpenings, the surface of the grinding wheel will fill with metal residue and grit. When this happens, the wheel should be cleaned or “dressed” with a diamond-tipped dressing tool.

Grizzly’s Model G3092 Dressing Tool is designed specifically for the Model G2790. For price and ordering information, see the latest Grizzly catalog. The optional dressing tool is designed to attach to the dressing tool holder (#19 in the parts diagram at the end of the man- ual) with the setscrew provided. To dress the Model G2790 grinding wheel:

1.Loosen the table lock lever under the table. Use the handwheel to raise the table.

2.Place the dressing tool holder on the fence above the right side of the grinding wheel and lower the optional diamond cutter through the hole in the holder.

3.Once the diamond-embedded end of the dresser comes in contact with the wheel, tighten the setscrew and move the holder so the diamond tip is just outside of the wheel’s diameter.

4.Turn on the grinder and slowly move the dressing tool across the top face of the stone. Move the dressing tool to the start- ing position, raise the wheel slightly with the handwheel and repeat.

Several light passes with the dressing tool will produce the best results, with the least amount of wear or damage to the wheel or the dressing tool. The fence will keep the dressing tool from reaching the inside edge of the wheel. Eventually, a ridge will form at that point. This will have no effect on the grinder’s operation.

Wheel Removal

After prolonged use, you may find it necessary to replace the grinding wheel. The procedure requires a 5/32" wrench. To change the wheel:

1.Remove the fence assembly.

2.Remove the wheel mounting flange.

3.Remove and discard the damaged or worn out wheel and replace with a new wheel. New wheels for the Model G2790 are avail- able through the Grizzly catalog. Check the latest catalog for ordering and price infor- mation.

4.Re-mount the flange and fence assembly.

Never allow visitors into your shop while assembling, operating, or maintaining tools and machinery. Keep your shop child-safe by locking up securely when not in use, and by providing proper supervision when chil- dren are present.
