4. Do not hold the work piece against the stone in a sharp angle against the
rotating direction of the stone. A kickback may result.

change in the material properties of the work piece. Therefore, allow the
work piece to cool down during work.

Replacing the Grinding Stones

1. To replace the stone, loosen
the three cross-head screws of
the outer side of the hood and
remove the outer part.
2. Now loosen the main retaining
nut of the stone with a suitable
open end or ring spanner. The
treads on the left hand side are
left hand treats; the nut is
loosened by turning clockwise.
3. Be careful not to confuse the nuts when putting them down. Hold the
stone in place to keep shaft and stone from turning and be able to loosen
the nut.
4. After the nut has been removed, the outer flange and the grinding stone
with the paper liners can be pulled off the shaft.
5. Before mounting, check the stone for damages visually and acoustically.
Visually check for cracks. After the visual check, gently percuss the stone
with a hard object. The sound must be clear and sound alike in all parts of
the stone. If the sound is dull, the stone is probably cracked and should
not be used.
Do not use a cracked stone, it is not able to withstand the loads of use
and may suddenly break up during use.
