4. PRODUCT DESCRIPTION
The fixture described in this manual is a cutting unit model SW12S which can be assembled
on automatic machines (e.g. spreaders, computerized cutting) by means of proper holes
located in the motor support.
SW12S can operate continuously and it can cut at various widths by means of multiple installation.
By cutting with the blade and the counterblade always in contact and thanks to the steel
upper quality of the blade supplied, SW12S guarantees the clean separation without frayings
of the two borders of the cut material. Moreover, the 220 Volt single-phase motor guarantees
a blade peripheral speed of 280 m/min allowing great cutting performances in terms of
traversing speed/speed of travel.
The 120 mm blade diameter and the power motor (180 Watt) of the cutting unit make it ideally
suited for small radius cut profiles on materials with thickness up to 5 cm. A sharpener assembled
on the cutting unit head allows sharpening the blade at any moment without disassembling it.
After carrying out this operation, it is possible to start cutting again. A high power motor,
perfectly balanced, with a high number of revolutions and totally free of maintenance, reduces
the vibrations to the minimum, so that the cutting unit SW12S complies with Italian Legislative
Decree No. 187 dated 19/8/2005, which adopts European Directive No. 2002/44/CE concerning
the risks deriving from mechanical vibrations. The mechanical parts are made of high resistance
steel, bronze and aluminium and require lubrication after several working hours.

6. NOISE LEVEL
It is advisable for cutting unit SW12S’s owners to verify the compliance with the standard
concerning safety of workers: Italian legislative decree N.277 ITEM IV (DATED 15-08-91).
The maximum acoustic pressure level emitted by cutting unit SW12S is about 60 dB (A).
Noise tests have been carried out in compliance with Standard ISO 11202 (1995). The
device noise levels, measured at different distances (without any sound wave filtering system),
vary in the extent of few db (A).
Cutting unit SW12S has been designed, manufactured and assembled to cut every kind of
fabrics or materials, with the exception of metal, plastic or wood, by means of rotary poligonal
blades.
This equipment must not work:
- in areas prone to explosions;
- in presence of fine dust or corrosive gases;
- on wet or damp materials;
- to cut plastic, metal and wooden materials.

8. USE WARNINGS
We recommend following the indications below in order to work in safety conditions.
•All the operations must be carried out complying strictly with the safety rules of the
country where the device is to be installed.
•It is STRICTLY FORBIDDEN to smoke during the installation or adjustment operations
of the cutting unit.
•The Customer undertakes to comply with and make his staff observe all the rules
and regulations in force concerning safety, prevention of accidents and health in the
work place.
Therefore, the Customer assumes the responsibility to strictly follow all the rules and
regulations in force, as well as the special provisions in force in sport and public
installations the Customer declares to know after receiving all the relative necessary
information.
•The cutting unit also works without its safety protective device. This protective device
must NEVER be removed.
•Always check the resistance of the material to be cut and the kind of blade which is
being used.
•The Customer shall equip his own personnel with all the individual safety protections for
the execution of the works, as well as with the ones which might be prescribed by the
Manufacturer due to specific danger conditions of the plant or of the area where the
personnel must work.
•Always pay attention to the electric cable position to prevent it from being cut or
damaged by the blade.
•It is allowed to assemble cutting unit SW12S on machines O.E.M. on condition that their
original structure is not modified. Otherwise, the intervention must be certified by Rasor®.
Firstly make sure that the lines and electric systems of the machine, on which the SW12S will
be installed, are able to supply the cutting unit with power correctly, in compliance with the
safety rules (for the feature required see par. 5).
We suggest installing a magnetothermic safety device before the cutting unit and check
that the ground circuit is effective. Before working on the feeding cable, unplug the unit.
Check that electric connections and protections correspond to the
driving force and to the plate data values (voltage and current),
required by the different electric circuits. Possible faulty ground
connections make the working conditions unsafe. Possible damages
are not charged to Rasor®. By referring to the EC 11-27/1 standard all
the works carried out by means of electric current must be performed
by a staff, who has been provided with all the devices required by
the above-mentioned standard. For the works carried out under
voltage, it is necessary that the employer certifies the suitability,
against formative processes. As the cutting unit SW12S is supplied
without plug, the user must use a plug homologated in the country
in which the cutting unit is used. In the European Countries a Shuko plug
is required (see picture 3). Never change the lenght of the cable supplied.
The cutting unit SW12S is a class II electric device; therefore, it does not
need earthing.

11. INSTALLATION AND USE
Even though the cutting unit is safe, operators must pay attention to preserve their and
other people’s safety.

At the end of the working operations, the motor could be very hot.

The cutting blade can work even if the protective device is disassembled.
To install and use the cutting unit manually, proceed as follows:
1) Fix the cutting unit on level squares or angles by means of four 5MA screws, by inserting
them in the four holes located in the motor lower cover (see pictures 4 and 5).
NOTE
The cutting unit can be installed in any position/angle: vertically, laterally and it can be turned
upside down. It is not necessary that the aluminium base touch the machine table.
1) Lay the material to be cut;
2) Plug the cutting unit into the electrical outlet (see picture 6);
3) Put the material on the cutting foot (see picture 7);
4) Adjust the front mobile protection according to the thickness of the material to be
cut (see picture 7);
5) Enable the switch; once it has been enabled, it lights up with a green light (see picture 8).
NOTE
Cutting unit SW12S can work in a fixed position (the material moves) or it can move forward
while the material is kept in the same position. Make sure the material to be cut is properly
stretched, preventing it from curling.

WARNING
Never use the two bolts which fix the motor to the cutting part to fasten cutting unit SW12S.
This operation may cause the motor shaft to break. In this case, warranty is not valid.

12. BLADE SHARPENING
13. LUBRICATION
Every 3-4 working hours, it is necessary to lubricate
the pair of gears. To carry out this operation, remove
protective plug “A” located on the motor support of
the cutting unit and fill it with lubricating grease Rasor.
Screw plug “A” again few turns. Screw plug “A” some
turns every 3-4 working hours (see picture 11).
The blade must never be dirty with grease or oil.
WARNING
After many hours of a continuative use of the cutting
unit, or if it would not be able to cut anymore, it is
necessary to sharp the blade.
To carry out this operation, start the blade and press
sharpener “2” located on it for 3-4 seconds (by
pressing push button “1”, as shown in picture 9).
Repeat the operation 2-3 times.
If the sharpening operation is not effective, check the
wear of emery grinding wheel “3” (see picture 10).
If emery grinding wheel “3” is too worn or dirty,
replace it.
14. MOTOR BRUSH REPLACEMENT
Worn motor brushes could create a cutting unit malfunction (no starting, intermittent start,
etc.), therefore it should be better to verify their wear periodically.
Open the motor cover by unscrewing 4 screws “4” on the cutting unit head (see picture
12). Remove the metal contacts that close the brushes with a slotted screwdriver (see
picture 13). Remove the brushes and check their wear: if the graphite has a length shorter
than 15 mm or it is uneven, replace it (see picture 14).
Close the metal contacts again by making sure that they adhere well to the metal part of the
brush. Finally close the motor cover again.
