4. PRODUCT DESCRIPTION
The fixture described in this manual is a pneumatic cutting unit model FP861A2 which can
be assembled on automatic machines (e.g. spreaders, computerized cutting, etc...) by means
of a proper bracket. Thanks to a reference pin on the front part and of an effective cutting
system with polygonal blade, this cutting unit can be used for many applications: in particular,
this cutting unit has been designed to cut hard materials such as moquette, polymeric
materials, fiber glass, insulating materials and leather (even rawhide).
One special feature of cutting FP861A2 is its ability to sharpen the blade in each moment
without disassembling it by means of a 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 to the majority of the air pipes. The turbine,
perfectly balanced, with a high number of revolutions and totally free of maintenance,
reduces the vibrations and the noise to the minimum. The cutting unit can be used to cut
damp or wet materials and therefore particularly recommended in tannery, 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 steel, high resistant
bronze and aluminium and require a lubrication after many working hours.

7. FIELD OF APPLICATION
The maximum acoustic pressure level emitted by cutting unit FP861A2 is about 72 dB (A).
Noise tests have been carried out in compliance with Standard UNI EN ISO 15744:2008. The
device noise levels, measured at different distances (without any sound wave filtering system),
vary in the extent of few db (A). The noise level has beeen detected with the silencer
supplied with the fixture assembled on the exhaust. The silencer must never be removed.
NOTE
It is advisable for cutting unit FP861A2 owners to verify the compliance with the standard
concerning safety of workers: refer to the Local Law.
Cutting unit FP861A2 has been designed, manufactured and assembled to cut textile or
technical fabrics, with the exception of metal, plastic or wood, by means of rotary blades.
This equipment must not work:
- in areas prone to explosions;
- in presence of fine dust or corrosive gases;
- to cut plastic, metal and wooden materials.
It is forbidden to use cutting unit FP861A2 for purposes
different from the above-mentioned ones.

12. BLADE SHARPENING
After using the cutting unit for some hours without
interruption, or if its cutting capacity is reduced, it is
necessary to sharpen the blade.
To carry out this operation, start the blade and press
sharpener “2” on the blade itself (by means of push
button “1”, as shown in picture 7) for 3-4 seconds.
Repeat this operation 2-3 times.
If the sharpening operation is not effective, check
the wear of emery grinding wheel “3” (see picture
8).
If grinding wheel “3” is too worn or dirty, replace it.
13. LUBRICATION
Every 3-4 working days, it is necessary to lubricate the
gear pair. In order to carry out this operation, remove
protective plug “A” located on the head of the cutting
unit and fill it with Rasor lubricating grease. Screw plug
“A” again a few turns. Screw plug “A” a few turns every
2-3 working days (see picture 9).
Once the plug is screwed until the end, fill it again.
There must not be stains of grease or oil on the blade.
