2.1 Machine installation
For the transport and delivery the machine is equipped with two casters at the front and two
steering rollers with a locking brake each at the back.
For a safe transport the brakes have to be
unlocked. The operator moves the machine
in the desired direction by pushing and
steering it from the back with the hands holding
on to back with the hands holding on to
the top.
No persons or objekts should be near or in
front of the machine during transport.
During the installation and transport of the machine see to it that the floor can withstand a
load of 400 Kg/m². The machine has to be positioned in such a way that a passable safety path
of one meter in width is all around the machine.
No objects, which could change the centre of gravity or the total weight should be lying on the
machine during transport.
The two locking brakes have to be
engaged once the desired process
location has been reached.
Check the structure and the slope of the
floor in order to guarantee a save position
of the machine.
The machine has to be positioned in such a way, that there is an unrestricted ceiling height of at
least 2,30 m so that the operator has an unrestricted working area above the machine.
2.2 Connection of the machine
Before connecting the machine to the mains, make sure that the power outlet is dimensioned
according to the machine datas. The High-Tech-Cutter SR1 and SR1 turbo is standard equipped
with a connected load of 400 V / 50 Hz / 16 A / 1,5 kW.

8
These values can vary, so take the values from
the data plate, positioned at the back of the
machine, before finally connecting the machine.
After an electrician has fitted a suitable power
plug to the power lead, the machine can be supplied
with power by connecting the lead to the power
point.
Turn the main switch from ”0” to ”1” to turn on
the machine.
Should it be impossible to start the machine
despite locking all safety devices, then the
rotang field has to be changed by an electrician
by changing over the two black leads inside
the power plug.
2.3 Commissioning of the machine
The operating manual has to be read and understood before commissioning the machine.
This is followed by cleaning and disinfecting of the machine according to the cleaning
instructions.
All accessories have to be checked for visible damage – a possible cause of the transport –
during the cleaning process. The same applies for the entire machine, especially the safety
devices
Switch ON the machine by turning the main
switch to „1“. Open the tool box.
Now clean and disinfect the entire tool box
according to the cleaning instruction.
Now clean and disinfect all HighTech-cutters and
hang them into the tool box.
Now the main switch has to be turned to ”0” so that the Rühle technician can activate the six
Self-lubricating systems inside the machine.
After turning the machine on the main switch on again, the first test-run can be carried out,
by selecting the desired cutting program and inserting the relevant Multi-cutter into the machine.

3. Operating instructions
3.1 Switching on the machine
To start the machine......
......the main switch has to be turned to position ”1”
......a trolley with a box has to be pushed under the cutting area door.
........the discharge funnel has to be installed inside the cutting area door.
......with a Multi-cutter installed, the shaft slider and the
cutting area door have to be closed.
......The ”ON” key on the operating panel has to be
activated.
Now the machine can be started, provided, that the Multi-cutter, prescribed in the
cutting program, has been inserted.
3.2 Cutting preperation
The machine has to be adjusted to the product prior to the cutting process.
The adjustment consist of inserting the correct multi grid combination, choosing
The right cutting length (forward feed length) and the best pre-compacting
Pressure. Pre-compacting has the funktion to press the product into a compact
Block inside the process chamber before the actual cutting process. Each product
Can only sustain a certain amount of pressure without beeing damaged.
Cutting Length:
With the forward feed adjusting lever it is
possible to choose cutting lengths between
1 mm and 30 mm.
To adjust the length the lever has to be
pulled away from the machine and turned
to the desired position.
Releasing the lever lets it slide back on to the
machine again.

10
Pre-compacting:
A simple rotary motion brings the
pre-compacting adjusting lever to the
desired position
from 0
( no compacting Presure )
to 10
( highest compacting pressure )
3.3 Cut adjustments
To vary pre-set cutting parameters it requires a great deal of cutting experience as well as a sound
knowledge of the machine in order to achieve the best cutting result without the machine suffering
any damage.
That’s why a variation of pre-set cutting parameters should only be changed after a written
confirmation by the Rühle GmbH. The best product adjustment is achieved with the help of a
Rühle service technician.
There is a choice of different adjustment variables for each product, taking different cut-sizes and
different cut goods into consideration.
It has to be considered however, that only those produkt parameter combinations can be used, for
which the HighTech-cutter has been supplied.

3.4 The Multi-cutter
The Multi-cutter determines two out of the three dimensions of the cube or stripe.
The size of the cutting dimension is in mm, which means that the distance between two adjacent
knives is x mm.
The following cut-sizes are available for the High-Tech-Cutter:
5 mm x 5 mm, 6 mm x 6 mm, 8 mm x 8mm, 10 mm x 10 mm, 12 mm x 12 mm, 16 mm x 16 mm
20 mm x 20 mm, 24 mm x 24 mm, 30 mm x 30 mm, 32 mm x 32 mm, 40 mm x 40 mm,
60 mm x 60 mm.
Because the two dimensions are determined by the composition of two Multiplex-cutter-halves, it is
possible to achieve all sorts of combinations like 6 mm x 60 mm.
A Multi-cutter consists of:
A HighTech-cutter frame on which all
HighTech-cutter parts are mounted and the
frame itself is attached to the machine.
The Multiplex-cutter-half Top is marked with
O (Over) and, as the second cutting stage,
moves one plane of knives.
The Multiplex-cutter-half Bottom is marked
with U (Under) and, as the first cutting stage,
moves one plane of knives.
Product stabilizers which keep the product in
place while the knives are cutting
A Multi-cutter doesn’t always have to be composed of all the single parts. If, for example long
stripes are required, the Multiplex cutter Bottom is not needed and therefore the stabilizers are not
mounted either.
In case of a very hard product like smoked ham or cheese there is no need for the stabilizers as
well.
The two Multiplex-cutter-halves are in all cases mounted in such a way, that the Multiplex cutter half
bottom represents the bigger cut size and the Multiplex-cutter-half Top the smaller one.

17
3.4.1 HighTech-cutter selection
This operating manual contains the correct grid selection for SR 1 and SR 1 turbo.
For the selection of the HighTech-cutter frame the following applies: Always select the frame
with the smallest number of slits. This results in the best cut.
Of course it is possible to take a HighTech-cutter frame with lots of slits.
Because a soft product is processed in this example and a Multiplex-cutter-half bottom is used, it is
possible to use product stabilizers.
3.4.2 HighTech-cutter assembly
The operator assembling the Multi-cutter has to wear protective gloves against cuts and stabs.
A.At first all necessary Multi-cutter parts have to
be put on a table with a non slippery surface.
Only use as many product stabilizers as
determined by the Multiplex-cutter-half bottom.
Is there provision for only one knife, only put one
knife on the table, never more.
Check the knives for damage and bluntness
without touching them with the hands.
Only if all parts don‘t show any signs of wear and
tear it ist allowed to assemble the Multi-cutter.
B.Put the bottom Multiplex cutter half with the
knife-edge facing down on to the bottom four
rollers of the Multi-cutter frame. Slide the Multiplex
-cutter half along the rollers until all four rollers
have engaged. The hook of the Multiplex
-cutter-half has to be on the right
hand side.

18
C. Now the product stabilizer(s) have to be inserted
into the Multi-cutter frame from the side, on top of
the knives of the bottom Multiplex-cutter-half.
The stabilizers are inserted so far, that they are
not protruding on either side of the Multi-cutter
frame. In case of no Multiplex-cutter-half bottom,
no product stabilizer is inserted.
This applies also, when there is no stabilizer
support in the Multi-cutter frame.
D. Now the Multiplex-cutter-half top is put on to the top
four rollers of the Multi-cutter frame. Slide the
Multiplex-cutter-half along the rollers, until all four
rollers have engaged.
Take note that the Multiplex-cutter-half marked with
”U” lies behind the Multiplex-cutter-half marked
with ”O”.
To dismantle the Multi-cutter after a cutting process,
it is necessary to follow the steps described under
A – D in reverse order.
The handle on the Multi-cutter allows the operator to
lift it slowly with one hand in order to attach the
Multi-cutter to the machine.
!
!

19
3.4.3 HighTech-cutter installation
Only install the Multi-cutter, which is nominated in the desired cutting program. The operator has to
wear protective gloves against cuts and stabs while working in the cutting area.
A. Open the processing shaft and remove
the shaft slider by sliding it diagonally
out of the guides on the side.
B. Turn the blade away from the cutting area,
so that the tip of the blade points to the floor.
C. Before sliding the Multi-cutter into the Multi-
cutter fastener, it has to be inserted into the sector
of the sheet metal as high up as possible.
Now the Multi-cutter can be inserted into the
fastener.
D. Turn the blade on the knife shaft twice by 360°.
If this can be done without any problems, the
process shaft and the cutting area door can be
closed again.
If it is not possible to turn the blade two
revolutions or to lock the shaft, it has to be
checked if the drive bolts have engaged properly in the drive hooks of the Multiplex-
cutter half.
After checking and rectifying the problem, the
blade again has to be turned twice by 360°.

20
3.4.4 HighTech-cutter maintenance
In the end a cutting machine always depends on sharp knives, because they keep the wear and
tear to a minimum and create a beautiful cut. For this reason, the Multiplex cutter halves and the
knives should be sharpened with a suitible tool every 50
operating hours. Please use special protective gloves
against cuts and stabs for this process!
Preferably use Rühle’s knife sharpener and it will only take
2 minutes to resharpen a complete Multiplex-cutter half.
For this purpose, the Multiplex-cutter half is positioned on a
non slippery table in such a way, that the knife edges face
the operator. First slide the knife sharpener along one side
of the knife and then on the opposite side.
Never exert too much pressure – this could result in an even blunter knife. Again use special
protective gloves against cuts and stabs.
The Rühle knife sharpener is well balanced and has as
one of its components Vidia steel. The construction of
the sharpener allows you to work even under very
cramped conditions without any problems. There is a
special hanger provided in the tool box to store the Rühle
knife sharpener.
3.5 The sectioning blade
All the time, when handling the sectioning blade, protective
gloves against cuts and stabs have to be worn.
For the sectioning blade too, the principle of the sharp
knife and the beautiful cut applies.
To install the sectiopning blade it has to be put on the
blade shaft in the cutting area first.
Now turn the sectioning blade around the stationary blade
shaft until it engages and can only be turned together with
the blade shaft.
Hold the sectioning blade in this position and at the same time
screw the wing nut counterclockwise onto the blade shaft, until
it touches the blade.
