The possible causes are:
• Drag marks if connection lines are led through win-
dow or door clearances.
• Kinks due to improper attachment or routing of the
connection line.
• Cuts caused by running over the connection line.
• Insulation damages caused by pulling the connec-
tion line out of the wall socket.
• Fissures caused by the aging of the insulation.
Such defective electrical connection lines must not
be used and are, due to the insulation damages,
life threatening!
Regularly check the electrical connection lines for
damages. 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 provi-
sions of the local power supply company. Only use
connection lines labeled with H07RN. The labeling
oftheconnectioncablewiththetypespecificationis
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 fol-
lowing:
• 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 com-
plete drive unit with the electric control.
9. Working Instructions
Direction of Grinding (Fig. 1 + 2)
It mainly depends on your requirements whether you
want to work with or against the direction of grind-
ing. 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 grind-
ing process is slowed down if you work with the direc-
tion of rotation.

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 + 4)
Fill the water reservoir with water up to the marking.
The grinding stone becomes saturated with water.
Refillwater,ifrequired.Donotgrindwithoutwater.
Once the grinding process is completed, lower the
water reservoir to prevent the grinding stone from be-
ing in the water for an extended period of time.
Empty the water reservoir regularly. Otherwise, par-
ticles 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 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 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
support in such a manner that the front end of the an-
gle measurer straightly borders the grinding stone.
Please make sure that the angle measurer is al-
ways 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)
Since the grindstone rotates only slowly, a move-
ment 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 pro-
duction 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.
