8. Working Instructions

Direction of Grinding (Fig. 1, Fig. 2)
It mainly depends on your requirements whether you
want to work with or against the direction of grinding.
If you want to quickly remove large quantities of steel
(e.g. from very old, rusty tools) or if you want to grind
coarse tools, such as axes, it is recommended to work
against the direction of grinding. If you want to grind
more precisely, we recommend to work with the direc-
tion of grinding. This applies, for example, to carving
tools and knives. Please note that the grinding process
is slowed down if you work with the direction of rota-
tion.
Please check before each operation whether the sur-
face of the grinding stone is even. To do so, lower the
universal support onto the stone and turn it manually
by 360°. If required, trim uneven material using the 250
trimming device.
Upon the time of delivery, the TiGer provides of even
surfaces.
Water Reservoir (Fig. 3, Fig.4 )
Fill the water reservoir with water up to the marking.
The grinding stone becomes saturated with water. Re-
fill water, if required. Do not grind without water.
Once the grinding process is completed, lower the wa-
ter reservoir to prevent the grinding stone from being in
the water for an extended period of time.
Empty the water reservoir regularly. Otherwise, parti-
cles of steel and trimmed stone will accumulate and
compress in the reservoir.
Expert tip: Such precipitations can be avoided if you
place a magnet into the water.
Speed controller (Fig. 5)
The speed of the grindstone and of the leather disc
can be controlled steplessly using the speed controller.
The speed depends on the required result. For grind-
ing, a speed in the lower range is more suitable. For
stripping with the leather disc, a higher speed is more
suitable.
At high speeds, there is a risk of splashing.
Lower the water container when working with the
leather disc at high speeds.
In order to maintain an even grinding speed with a de-
creasing grindstone diameter, the speed can be ad-
justed steplessly with the speed controller.

Angle Measurer (Fig. 6)
Measure the angle of the grinding bezel by compar-
ing the cutting edge to the notches. Then, you set the
determined angle at the device by changing the height
of the universal support. To do so, perform the follow-
ing steps:
First, clamp the tool into the device and insert the de-
vice on the universal support.
Then, hold the angle measurer with the desired an-
gle at the tool tip. Now, adjust the height of the univer-
sal support in such a manner that the front end of the
angle measurer straightly borders the grinding stone.
Please make sure that the angle measurer is always in
alignment with the tool tip.
Note: The values indicated on the angle measurer
are only standard values. Of course, you can change
these values according to your requirements.
Grinding (Fig. 7)
Since the grindstone rotates only slowly, a movement
can be seen in the lateral direction. This is normal and
does not exert any negative influence on the grinding
result.
Expert tip: New tools still show traces of the production
process. You can substantially increase the lifetime of
your tools if you grind them on both sides of the cutting
edge before the first application. You simply grind the
back side in the free­handed mode on the vertical of
the grinding stone, and the front side as follows.
After you have set the angle, insert the tool mounted in
the device on the universal support, turn on the motor,
and start the grinding process. Press the tool evenly
onto the grinding stone near the cutting edge, and
move it crosswise across the stone.
Please make sure that at least half the width of the cut-
ting edge comes into contact with the grinding stone at
any time to avoid damages of the stone.
To achieve finer grinding results, prepare the stone
using the Stone preparer. Thereby you increase the
graining from 250 to approximately 1000. The SP is
available as an accessory from your scheppach dealer.
The height of the Universal Support can be set exactly
with the knurled nut attached to the Universal Support.
Sharpening (Fig. 8)
Never sharpen against the direction of grinding! Other-
wise, the tool will cut into the leather!
Impregnate the leather disc using weak machine oil.
Then apply abrasive paste on the leather disc. Turn
on the device, and distribute the abrasive paste by
pressing the ground tool with circular movements on
the wheel.
These preparations are sufficient for five to ten tools.
Then, you start again with a new layer of machine oil,
followed by new abrasive paste. These measures in-
crease the lifetime of the leather and the quality of your
tools.
Expert tip: You can work in the free­handed mode for
the trimming itself. You achieve a more precise result if
you keep the tool in the device in the position in which
you ground the tool.
