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.
