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.

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.

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.
