Changing a grinding wheel
Nut
Plate flange
Loosen the nut holding the grinding wheel to the shaft. Carefully remove the left handed nut, the
plate flange and the soft washer that is clamping the grindstone in place. (See figs 8 & 9) Then,
very carefully remove the grindstone from the shaft, take care that no damage or distortion is
done to the bush (if one is fitted). (See fig 10) Now is a good time to clean out the interior of the
wheel guard, removing any loose or compacted material that may have accumulated. Carefully
inspect the new grinding wheel before it is fitted, check that there are no cracks, and there is no
damage to either the front face or the edges. If required, fit the bush to the grindstone. Carefully
mount the grindstone onto the shaft, reposition the soft washer and the wheel flange, replace the
holding nut and tighten carefully.
Do Not Overtighten.
Refit the outside shell of the wheel guard
and secure with its nuts and bolts. Refit the tool rest, positioning as in “Setting up the grinder”.
Fasten securely.

carefully aside. (See figs 6 & 7)
