4. PRODUCT DESCRIPTION
The fixture described in this manual is a pneumatic cutting unit model FP120M which can be
assembled on automatic machines (e.g. spreaders, computerized cutting). FP120M can operate
continuously and it can cut at various heights by means of multiple installation. Thanks to
the presence of a 1HP pneumatic motor, FP120M is able to cut difficult materials with
thickness up to 50 mm. It is particularly suitable for technical fabrics and composite materials.
By cutting with the blade and the counterblade always in contact and thanks to the steel
upper quality of the blade supplied, FP120M guarantees the clean separation without frayings
of the two borders of the cut material. One special feature of cutting unit FP120M is its ability
to sharpen the blade in each moment without disassembling it by means of a emery grinding
wheel mounted on the cutting unit head. After carrying out this operation, it is possible to
start cutting again. The pneumatic cutting unit is provided with a threaded connection suitable
for most of the air pipelines. A high power motor, perfectly balanced, with a high number of
revolutions and totally free of maintenance, reduces the vibrations to the minimum, thus
making the cutting unit comply with European Directive No. 2002/44/EC concerning the
risks deriving from mechanical vibrations. The cutting unit can be used also to cut damp or
wet materials; therefore it is recommended in tanneries, dyeworks, etc. The use of compressed
air as source of energy allows working continuously without problems of heating or motor
overload. The mechanical parts are made up of high quality steel, bronze and aluminium and
require a lubrication after many working hours.

9. RESIDUAL RISKS
Even though the cutting unit is safe, operators must pay attention to preserve their safety
and that of others.


The cutting blade can work even when the protection device is disassembled.
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 relevant necessary
information.
•The cutting unit works even without its safety protection device. This protection
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.
•Do not perform any adjustment while the blade is working.
•Always pay attention to the air pipe position to prevent it from being cut or damaged
by the blade.
•It is allowed to assemble cutting unit FP120M on machines O.E.M. on condition that
their original structure is not modified. Otherwise, the intervention must be certified by
Rasor®.

10. INSTALLATION AND USE
To install and use the cutting unit proceed as follows:
1) Fix the cutting unit directly on the motor body by means of two half rings and screw
them by means of two socket head screws (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 touches the machine table.
2) Lay the material to be cut;
3) Connect the air pipe to the quick connection “A” (not supplied) (see picture 6);
4) Set the pressure gauge (option) to 6 bar;
5) Put the material on the cutting foot (see picture 7);
6) Adjust the front mobile protection according to the thickness of the material to be cut;
7) Enable the air remotely and carry out the cutting operation.
NOTE
Cutting unit FP120M 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.
4
WARNING
Do not tighten the two socket head screws, so as to avoid that the two half rings
deform the motor. Consider that the motor has a diameter of 65 mm (see picture
4). In this case, warranty is not valid.

13. LUBRICATION
Every 3-4 consecutive working days, it is necessary to
lubricate the pair of gears. To carry out this operation,
remove protective plug “A” located on the cutting unit
head and fill it with lubricating grease Rasor.
Screw plug “A” again few turns.
Screw plug “A” some turns every 2-3 consecutive working
days (see picture 9).
The blade must never be dirty with grease or oil.
WARNING
12. BLADE SHARPENING
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
emery grinding wheel “2” located on it for 3-4 seconds
(by pressing push button “1”, as shown in picture 7).
Repeat the operation 2-3 times.
If the sharpening operation is not effective, check the
wear of emery grinding wheel “3” (see picture 8).
If emery grinding wheel “3” is too worn or dirty, replace
it.
14. PNEUMATIC MOTOR
In case of technical problems with the pneumatic motor, the entire motor must be
sent to Rasor®. Never disassemble the pneumatic motor since it could jeopardize
the guarantee.

If the blade is no more able to cut (even after repeating
the sharpening operation several times) it is necessary to
replace it. To carry out this operation, use butterfly wrench
“1” and drift “3” locking the blade (shown in picture 10).
To replace the blade, proceed as follows:
1) Use some protective gloves in compliance with Italian
Legislative Decree 81/08;
2) Remove the fixed rear safety protection “A” (see
picture 11) by unscrewing the cross-slotted screw
“C” and the cross-slotted screw “D” by means of
the proper screwdriver (not supplied by the
manufacturer) as shown in picture 12. Remove the
movable front safety protection “B” (see picture
11) by unscrewing pin “E” and the two washers
“F” as shown in picture 12.
3) Insert drift “3” (see picture 10) into hole “G”, so as
to lock the blade (the hole on the blade must
correspond to the one on the structure).
4) Use butterfly wrench “1” to unscrew nut “H” and
remove blade “L” (see picture 13).
5) Replace the worn blade with the new one “2”,
being careful to center the blade on the gear, in
the correct position; we remind you to assemble it
so that the side with the writing Rasor can be seen
by the operator.
6) Assemble all the components again and carry out
the sharpening.
