The machine has variable speed 100-
200 RPM to adapt to various
sharpening and honing purposes.
With the variable speed control knob

As the diameter of the stone wheel
reduces during use the variable speed
allows compensating for it.

6.1 Stone wheel dressing

The supplied dual surface stone grader
(Q) dresses the stone wheel for fine or
coarse sharpening.
Fig 5
Start the machine.
Move the stone grader left/right for
even dressing of the stone.
Applying the 2 surfaces of the stone-
grader changes the stone-wheel from
coarse to fine and back again.
Use the stone grader to sharpen the
grit of the stone whenever needed.

6.2 Tool grinding

Tools to be sharpened must be held in
the appropriate fixture and be guided
firmly so it can not move or fly off
during the sharpening process.
Never perform any operation
freehand.
In most cases you will achieve the best
result if you grind against the wheel
(Fig 6).
The wet sharpener may have to be
turned around to get to a convenient
operating position.

Move the tool left/right as you grind
for even wear of the stone.

For a quick burr removal, alternately
hone both sides of the cutting edge.
Always hone with the wheel (Fig 7).
The wet sharpener may have to be
turned around to get to a convenient
operating position.
Attention:
Never attempt to hone a tool against
the rotation, the tool will be thrown
away and the honing wheel be
damaged.
