Changing the dry grinding wheel...
Check that the spark guard and the tool rest are not touching the grindstone. Reconnect the
grinder to the mains supply, give the grinder a 'short burst', by switching it on and off
quickly. Check the grinder is not subject to any undue vibration. If the grinder does vibrate,
strip it down again and check that the bush (if fitted) is correctly positioned and is the
correct size for the stone and the spindle. Check the bore of the stone is correct. If these all
seem correct, refit and carry out the 'quick burst' procedure again. If the machine is still
vibrating, discard the stone and replace with another one. Run up to speed normally. Leave
the machine running for at least one minute before carrying out any work. Apply a
workpiece and check that the spark guard is correctly positioned and that the tool rest is
securely fixed.

Changing the wet grinding wheel...
1. Remove the rubber stabilising foot (See fig 3).
2. Drain the water from the trough.
3. Release the four screws that secures the tool jig cast iron support to the gearbox and put
carefully aside (See figs 15 & 16).
4. Release the remaining screws that secures the trough to the gearbox (See figs 17 & 18).
5. Remove the trough and stand the grinder upright (See figs 19 & 20).
6. Undo the nut, (fig 21) and remove the wheel flange (fig 22) and the stone (fig 23).
NOTE.
Take care removing the flange or the stone from the flange as the flanges form the
bushing to size the grindstone bore to the gearbox shaft (See fig 23).
