The wet sharpener may have to be turned to a more
convenient operating position.
Check that support arm is parallel to wheel surface.
Generally, you will achieve the best result by grinding
against
the wheel. See Figure 9-2.
Figure 9-2 (optional straight edge jig shown)
Move the tool left/right to ensure even wear across the
wheel.
Narrow or convex cutting edges require less pressure.
Use both hands to stabilize the tool/jig during the
sharpening process.
9.3 Tool honing
See Figure 9-3.
Honing is used to remove burrs from the sharpening
process, and to develop a very fine edge on a tool.
It is recommended to rub a very light application of
machine tool oil onto the honing leather before
proceeding.
Apply honing compound to the honing wheel. A piece
of card can be used to spread it evenly on the wheel
as the wheel is rotating on slow speed. If honing
performance begins to diminish, reapply compound.
For quick burr removal, alternately hone both sides of
the cutting edge.
Always hone with wheel rotation. See Figure 9-3.
Do not attempt to hone against the
wheel (A, Figure 9-3); the tool will catch and may
be forced from the hand. Also, the honing wheel
will be damaged.

10.0 User Maintenance
For safety, turn the switch to OFF and remove plug
from the power source outlet before adjusting and
maintaining the wet sharpener. If the power cord is
worn, cut or damaged in any way, have it replaced
immediately.
10.1 Care of grinding wheels
In normal use, grinding wheels may become cracked,
grooved, rounded at the edges, chipped, out of true or
loaded with foreign material.
Cracked wheels should be replaced IMMEDIATELY.
The other conditions can be remedied with a dressing
tool. See sect. 9.1.
Do not store a wet stone in freezing temperatures.
When machine is not in use, remove water tank. The
stone wheel should not sit idle in water for long periods
of time.
Frequently empty the water tank, and refill with fresh
water. Clean out debris or shavings.
10.2 Wheel replacement
Before replacing a grinding wheel, perform a “ring test”
on the replacement wheel as follows. The wheel must
be completely dry.
1. Loop a piece of string through the grinding wheel
hole and suspend the wheel by holding up the
string.
2. Tap the wheel with a piece of scrap wood or a
wooden dowel.
3. A good wheel will “ring”; a defective wheel will
“thud”. Discard any wheel that does not "ring".
