4. PRODUCT DESCRIPTION
The fixture described in this manual is a pneumatic cutting unit model FP120DT which can be
assembled on automatic machines (e.g. spread ers, c omputerized c utting). FP120DT can operate
continuously and it can cut at various heights by mean s of multiple installation. T hanks to th e
presence of a double hard metal counterblade and of a double air inlet, FP120DT is able to cut
in both the directions, saving so a stroke and therefore time in the cross-cut processes. Thanks
to the presence of a 645W pneumatic motor, FP120DT is able t o 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, FP120DT guarantees the clean separation without frayings of the
two borders of the cut material. One special feature of cutting unit FP120DT is its ability to
sharpen the blade in each m oment without disassembling it by means of a emery gri nding wheel
mounted on the cutting un it head. After ca r r y i ng out this op er ati on, i t i s p ossi b l e to star t c utting
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 fr ee of maintenance, r educ es the vibrati ons to the minimum, thus maki ng the cutti ng 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 co mpressed air as sourc e 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.

10. INSTALLATION AND USE
To in stall and use t he cutt ing 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 an air pipe to the quick connection “A” and an air pipe to the quick connection
“B” (not supplied) in order t o carry out a bidirectiona l cut (see picture 6);
4 ) Set the pres sur e gau ge (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 re motely and carry out the cutting oper ation in one di rection or in the opp osite one.
NOTE
Cutting unit FP120DT can work in a fixed position (the material moves) or it can move
forward while the m aterial is kept in the same position. Make sure the material to be cut is
properly stretched, preventing it from curling.
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 va lid.
11. AIR PRESSURE GAUGE (OPTION)
8
The cutting unit must be necessarily supplied with
lubricated air with a pressure of 4-6 bar.
Rasor
®

The unit shown in picture 8 is made up of:
1 - p re ss u re reducer;
2 - valve to drain the condensate;
3 - drip-feed oiler unit;
4 - oil tank;
5 - pressure gauge;
6 - condensate tank;
7 - pipe fitting to connect the quick connection to the network;

13. LUBRICATION
Every 3-4 consecutive working days, it is necessary to
lubric ate the pa ir of gea rs. To carry out this opera tion,
remove protective plug “A” located on the cutting unit
head a nd fill it wit h lubri catin g grea se Ra sor.
Screw plug “A” again few turns.
Screw plug “A” some turns every 2-3 consecutive working
days (see pi ctu re 9 ).

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 b lad e.
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 , replac e
it.
14. PNEUMATIC MOTOR
In case of technical problems with the pneumatic motor, the entire motor must be
sent to Ra sor®. Never disa ssemble the pneumat ic motor since it could jeopardiz e
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” lo cking the blade (sho wn 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 t he cross-slotted s crew “D” by means o f
the proper screwdriver (not supplied by the
manufacturer) as shown in picture 12. Remove the
movable front safety protection “B” (see picture
11)
b
y unscrewing pin “E” and the two washers
“F” as sho wn in picture 12.
3) I
nsert 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 stru cture).
4)
U
se 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 wi th the writi ng Rasor can b e seen
by the operator.
6) A
