10. Operation

ATTENTION!
Remove the mains plug before any maintenance,
modification and assembly work.
10.1 Grinding direction (Fig. 4 + 5)
This primarily depends on whether you wish to work
with or against the grinding direction.
If you wish to remove large quantities of steel quickly
(e.g. from very old, rusty tools) or if you want to grind
coarse tools such as axes, it is advisable to work
against the grinding direction.
If you wish to grind more accurately, we recommend
working with the grinding direction. This applies, for
example, when grinding tools and blades.
Please note that the grinding process is slowed down
when you work with the direction of rotation. Please
check before each operation that the surface of the
grindstone is flat. To do this, lower the workpiece sup-
port onto the stone and turn it manually through 360°.
If necessary, break off uneven material with a stone
cutter.
10.2 Water tank (Fig. 7)
• Fill the water tank with water up to the recess. The
grindstone absorbs water; top up water if neces-
sary. Do not perform grinding without water. Since
the diameter of the grindstone decreases with the
number of grinding operations, the grindstone (12)
will no longer touch the water in the water tank (8).
The grindstone can no longer absorb water. If nec-
essary, the water tank (8) must be placed in the
upper holder for the water tank (16).
• When the grinding process is complete, lower the
water tank to prevent the grindstone from remain-
ing in the water for an extended period of time.
• Empty the water tank regularly. Otherwise steel
particles and grinding dust will accumulate in the
reservoir and compact.
• Expert tip: Such accumulations can be avoided by
placing a magnet in the water.
10.3 Angle gauge (Fig. 8)
Measure the angle of the workpiece by comparing
the cutting edge with the notches. Then set the de-
termined angle on the device by changing the height
of the workpiece support. To do so, perform the fol-
lowing steps:
• First clamp the tool in the device and place the de-
vice on the workpiece support
• Then hold the protractor with the desired angle to
the tool tip.
• Now adjust the height of the workpiece support
so that the front end of the protractor lies directly
against the grindstone. Please make sure that the
protractor is always aligned with the tool tip.

• Note: The values indicated on the protractor are
only guidelines. You can naturally change these
values according to your requirements.
10.4 Grinding (Fig. 9) with the fixture for chisel
Since the grindstone rotates only slowly, it is possi-
ble to detect movement in a lateral direction. This is
normal and has no negative influence on the grinding
result.
Expert tip: New tools still show traces of the produc-
tion process. You can significantly extend the service
life of your tools if you grind them on both sides of
the cutting edge before the first use. Simply grind the
back in freehand mode on the vertical of the grind-
stone and the front as follows:
• After you have adjusted the angle, insert the tool
mounted in the device into the universal holder,
switch on the engine and start the grinding process.
• Press the tool evenly onto the grindstone near the
cutting edge and move it laterally across the stone.
• Please make sure that at least half of the cutting
edge width is always in contact with the grindstone
to avoid damage to the stone.
• To achieve finer grinding results, prepare the stone
with a stone preparer. This increases the grain size
from 250 to approx. 1000.
10.5 Honing (Fig. 10)
Never sharpen against the direction of the leath-
er honing wheel! Otherwise the tool will cut into
the leather!
• Impregnate the leather honing wheel with machine
oil.
• Then apply the grinding paste to the leather honing
wheel.
• Switch on the device and spread the grinding paste
by pressing the workpiece onto the wheel with cir-
cular movements.
• These preparations are sufficient for five to ten
tools.
• Then start again with a new layer of machine oil,
followed by grinding paste. These measures in-
crease the service life of the leather and the quality
of your tools.
• Expert tip: You can hone in freehand mode. For a
more accurate result, remove the tool with the aid
of the appropriate fixture.
10.6 Grinding with the fixture for axes (Fig. 8)
For axes with a length of up to 170 mm. Larger axes
are ground without using a grinding support on the
tool support.
• The fixture consists of a wedge-shaped support into
which the axe is clamped when grinding against the
direction of the cutting edge.
• If necessary, the leather honing wheel can be re-
moved to create more space for the handle.
• Honing: Always sharpen with the direction of
rotation.
