Adjust the spark guard until it is
just clear of the grindstone
Position the eye shield on its pivot bolt, (if necessary, 'nip' the clamping bolt of the eye
shield clamp so that the eye shield remains in place).
If there is any tendency for the grinder to move, tip or tilt while it is being operated, it should
be bolted down; either to the bench or to a specific stand or base board.
It is a good idea to dress new grindstones before use, to remove any possible irregularities,
and ensure the stones are running concentrically.
Carry out a final check e.g. start the machine, check it runs smoothly. Check that the spark
guard is adjusted down to the stone, check the gap between the tool rest and the stone is
correct, check the stone is not badly deformed (rounded edges, grooved face, etc; unless
you have specifically shaped the stone to these profiles)check the eye shield is correctly
positioned. Have a cooling pot to hand if you need it, and remember safety goggles are a
good investment. (you are only issued with 1 pair of eyes).
Finally, fill the water trough with clean water to a level about 15-20 mm below the lower lip of
the trough.
NOTE.
The Wetstone will shed the grinding waste and dust into the water; the heavy waste
is not a problem as it will sink to the bottom of the trough, the dust and 'light stuff' will form
a film on the surface of the water and can be dragged up and lay on the stone. A sufficiently
heavy layer can be 'glazed' onto the stone by the grinding action, which reduces its cutting
efficiency. The 'heavy' waste which sinks to the bottom of the trough, can also start to rust,
due to the oxygenated nature of the water, (air trapped in the surface water on the stone,
being passed through the trough as it rotates). Clean the trough and refill with clean water
frequently.

Leave a gap of approximately
one and a half millimetres
between the grindstone
and the rest
