5. Machine operation
Always wear the approved working
outfit.
Use safety goggles at all times.
Never place your hand near the
machining area, grinding stone and
honing wheel while machine is in
operation.
Flying sparks can occur when grinding
dry. They can cause injury and ignite
flammable materials.
Remove defective abrasive wheels
immediately.
Tools are sharp and can lead to heavy
injuries, always handle them with care.
Make certain the switch (I) is in the
OFF-position before connecting the
machine to the power supply.
5.1 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.
5.2 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.
Fig 6
Move the tool left/right as you grind
for even wear of the stone.
Narrow or convex cutting edges
require little pressure only.
5.3 Tool honing
Apply some honing compound (R) to
the leather honing wheel (A).
Fig 7
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.
6. Setup and adjustments
6
Make all adjustments or
maintenance with the
machine unplugged from
the power source.
6.1 Sharpening jig setup
Use the existing angle measuring
device (T) to establish the tools
existing cutting edge.
Fig 8
Clamp the tool in the appropriate jig.
Adjust the support arm (G, Fig 9) and
change the tool clamping position to
get to the wanted grinding angle.
Fig 9
Use the angle measuring device (S) to
inspect the angle in relation to the
stone wheel.
Note:
The stone diameter needs to be set on
the scale (X) to get correct angle
reading.
6.2 Torque adjustment
During heavy machining the friction
drive may slip.
Therefore a torque adjustment has
been installed to the machine.
