Check that the spark guards and the tool rests 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 carryout 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.
If necessary dress the new stone lightly to ensure a 'good face' and good concentricity.
