Working Instructions - Scheppach TIGER 2500 Bedienungsanleitung

Regularly check the electrical connection lines for dam-
ages. Please make sure that the connection lines are
disconnected from the mains supply during the check.
Electrical connection lines must meet the applicable VDE
and DIN regulations and the provisions of the local power
supply company. Only use connection lines labeled with
H07RN. The labeling of the connection cable with the
type specification is required.
A.C. Motor
• The supply voltage must be 220÷240 V/50 Hz.
• Extension lines up to a length of 25 m must have a
minimum cross section of 1.5 mm², lines with a length
exceeding 25 m must have a minimum cross section
of 2.5 mm².
• The mains connection is protected with a maximum of
16 A.
Connections and repairs of the electrical equipment may
only be performed by an electrician.
If you have further questions, please specify the follow-
ing:
• Motor manufacturer and type
• Kind of current of the motor
• Data from the machine type plate
• Data of the electric control
If you return the motor, always return the complete
drive unit with the electric control.

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 direction 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 rotation.
Please check before each operation whether the surface
of the grinding stone is even. To do so, lower the univer-
sal 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 sur-
faces.
Water Reservoir (Fig. 3, Fig. 4)
Fill the water reservoir with water up to the marking. The
grinding stone becomes saturated with water. Refill wa-
ter, if required. Do not grind without water.
Once the grinding process is completed, lower the water
reservoir to prevent the grinding stone from being in the
water for an extended period of time.
Empty the water reservoir regularly. Otherwise, particles
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.

Angle Measurer (Fig. 5)
Measure the angle of the grinding bezel by comparing
the cutting edge to the notches. Then, you set the deter-
mined angle at the device by changing the height of the
universal support. To do so, perform the following steps:
First, clamp the tool into the device and insert the device
on the universal support.
Then, hold the angle measurer with the desired angle at
the tool tip. Now, adjust the height of the universal sup-
port 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. 6)
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 free-handed 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 cutting 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.
Sharpening (Fig. 7)
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, fol-
lowed by new abrasive paste. These measures increase
the lifetime of the leather and the quality of your tools.
Expert tip: You can work in the free-handed 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.
