4. PRODUCT DESCRIPTION

This manual describes pneumatic scissors model FP503, which are used in order to quickly
cut fabrics in the textile industry and other materials. They are extremely versatile, light and
precise in the cutting operation. Thanks to the use of a new foot, the cutting procedure is
very quick and effective, even when the bending radius is particularly narrow. One special
feature of pneumatic scissors FP503 is their ability to sharpen the blade in each moment
without disassembling it by means of a grinding wheel mounted on the scissors head. After
carrying out this operation, it is possible to start cutting again. The pneumatic scissors are
provided with a threaded connection for many air pipeline. 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 pneumatic scissors can be used also outdoor and to cut damp or wet materials and
therefore particularly recommended in tannery, dyeworks, etc. The pneumatic scissors FP503
are extremely light (they weight only 790g) and handy and allow carrying out quick and
precise cuts. 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
and high resistant bronze and require a lubrication after many working hours.

7. FIELD OF APPLICATION

6. NOISE LEVEL

The maximum acoustic pressure level emitted by pneumatic scissors FP503 is about 60 dB
(A). Noise tests have been carried out in compliance with Standard UNI EN ISO 11202:2010.
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 been detected with the silencer
supplied with the fixture assembled on the exhaust. The silencer must never be removed.

NOTE

It is advisable for pneumatic scissors FP503 owners to verify the compliance with the standard
concerning safety of workers: Italian legislative decree 81/08. The use of ear protecting devices
is compulsory.

Pneumatic scissors FP503 have been designed, manufactured and assembled to cut fabrics or
technical materials, with the exception of metal, plastic or wood, by means of rotary circular,
decagonal or hexagonal 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 pneumatic scissors FP503 for

purposes different from the

above-mentioned ones.

8. USE WARNINGS

We recommend following the indications below in order to always work in safety conditions.

· All the operations must be carried out complying strictly with the safety rules of the
country where the machine is to be installed.

· It is STRICTLY FORBIDDEN to smoke during the installation or adjustment operations of
the pneumatic scissors.

· 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 pneumatic scissors work even without their 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.

· Only one operator must use the pneumatic scissors always standing behind the guide
handle. Do not make any adjustment while the blade is working.

· Always pay attention to the position of the air pipe to prevent it from being cut or
damaged by the blade.

· It is allowed to assemble pneumatic scissors FP503 on machines O.E.M. on condition
that their original structure is not modified. Otherwise, the intervention must be certified
by Rasor®.

· The pneumatic scissors FP503 are equipped with double safety push button with a lever
and a ratchet on the handle: the ratchet prevents the start push button from being
enabled accidentally, the lever operates the scissors. Never remove the ratchet.

9. RESIDUAL RISKS

10. USE

Even though the pneumatic scissors are safe, operators must pay attention to preserve their
and other people’s safety.

L The cutting blade can work even when the protective device is disassembled.

To use the pneumatic scissors manually, proceed as follows:

1) Lay the material to be cut on the table;

2) Connect the air hose to the quick connection “A” (not supplied) (see picture 3);

3) Set the pressure gauge (option) to 6 bar;

4) Put the material on the cutting foot (see picture 4);

5) Push the starting lever after moving the safety device (see picture 5);

6) Push the pneumatic scissors in the desired direction, being careful to keep the material
in front of them as stretched as possible and preventing it from curling in the front part
of the scissors.

NOTE

The thrust on the pneumatic scissors must be as uniform as possible. To carry out linear cuts
with precision (and to follow predetermined paths), we also recommend using the arrow
point (see point “B” in picture 6).

11. AIR PRESSURE GAUGE (OPTION)

7

The pneumatic scissors must be necessarily fed with
lubricated air with a pressure of 4-6 bar.
Rasor® offers, as option, a reduction unit filter with a
pressure gauge already calibrated with the quantity
of oil to be delivered.
The unit shown in picture 7 is made up of:

1 -pressure 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;

8 -pipe fitting to connect the quick connection to the scissors.

For the use and maintenance read the instruction sheet supplied with the filter.

12. BLADE SHARPENING

After many hours of a continuative use of the pneumatic
scissors or if they are not 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” on the same one (by pressing sharpening
button “1” as shown in picture 8) for 3-4 seconds. Repeat
this operation 2-3 times.

If the sharpening process should be ineffective, check the
wear of the emery grinding wheel “3” (see picture 9). If
wheel “3” is too worn or dirty, replace it by removing the
blade by means of the proper tool.

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 pneumatic
scissors and fill it with the grease supplied. Screw plug
“A” again a few turns. Screw plug “A” a few turns every
working day (see picture 10) when the machine is used
without interruption.

The blade must never be dirty with grease or oil.

14. BLADE REPLACEMENT

10

WARNING

A

If the blade is no more able to cut (even after repeating the
sharpening operation several times) it is necessary to replace
it. In order to carry out this operation, use butterfly wrench
“1” and drift “3” locking the blade (shown in picture 11).
In order to replace the blade, proceed as follows:

1)Use some protective gloves in compliance with
Italian Legislative Decree 81/08.

2)Remove safety protection “B”, by unscrewing the two
slotted screws “A” by means of a screwdriver (not
supplied by the manufacturer), as shown in picture 12.

3)Insert drift “3” (see picture 13) into hole “C” in
order to lock the blade (the hole in the blade must
correspond to the hole in the structure).

4)Use butterfly wrench “1” in order to unscrew nut
“D” and remove blade “E” (see picture 14).

5)Replace the worn blade with the new one “2”, being
careful to center the blade on the gear, in the correct
position, and remember to assemble it with its sharp
side (the one with the writing Rasor) positioned
towards the external side of the pneumatic scissors.

6)Assemble all the components again and carry out
some cutting and sharpening tests.
