3.5 Grinding stone dressing
A diamond dresser is supplied, tted to the grinding head.
The grinding stone should be dressed periodically, by
adjusting the dresser towards the stone with the secondary
control knob that draws the dresser onto the stone. Then rotate
the control knob back and forth making a few light passes of
the dresser, to ensure that the stone does not become “loaded”
(clogged). New stones should ALWAYS be dressed!
There is no necessity to alter the set up to do this. The cut
can simply be taken off with the single point feed handwheel
and the stone can be dressed mid way through a grind, if
necessary.
Ensure that adequate eye / breathing protection is used.

3.6 Grinding stone replacement
Isolate the electrical supply. Rotate the mounting bar so that the top face (magnets) face
the operator. Wind the grinding head back to it’s rear-most position (nearest the operator)
Insert a 6mm hex key into the socket at the rear of the motor and undo the grindstone nut
with the box spanner provided.
Before tting a replacement stone, the new stone should be carefully examined for
damage. It should be held loosely and “rung” by tapping gently with a non-metallic object
such as a screwdriver handle. A sound stone will make a clear ringing noise. Reject a
stone that sounds “dead”. Ensure that there is no loose grit/debris between the stone and
the mounting anges.
