4. PRODUCT DESCRIPTION
The fixture described in this manual is a pneumatic cutting unit model FP120SM which can
be assembled on automatic machines (e.g. spreaders, computerized cutting). FP120SM can
operate continuously and it can cut at various heights by means of multiple installation.
Thanks to the presence of a 1HP pneumatic motor, FP120SM 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, FP120SM guarantees the clean separation
without frayings of the two borders of the cut material. One special feature of cutting unit
FP120SM 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.

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 FP120SM 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
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.
