4. PRODUCT DESCRIPTION

Safety device to enable the control

The fixture described in this manual is a pneumatic scissor model FP503MT which is used in
order to quickly cut composite materials, in particular the carbon fibre. It is extremely versa­tile, light and precise in the cutting operation. Thanks to the use of a supporting front foot
and of an effective cutting system with heptagonal, circular or decagonal blade, it is possible
to use the pneumatic scissors for the precise mold trimming.
One special feature of pneumatic scissors FP503MT is their ability to sharpen the blade in

EN

each moment without disassembling it by means of a grinding wheel mounted on the scissors

22

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 and for the carbon fibre cut.
The pneumatic scissors FP503MT are extremely light (they weight only 790g) and handy and
allow carrying out quick and precise cuts, even with curve profiles. 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

Pneumatic scissors FP503MT have been designed, manufactured and assembled to cut every
kind of ordinary or technical fabrics, with the exception of metal, plastic or wood, by means
of rotary circular, decagonal or heptagonal 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 FP503MT 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

EN

24

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 FP503MT 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 FP503MT 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

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.

10. USE

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).

7

6

7

After using the machine for some hours without
interruption, or if the machine 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 8) for 3-4 seconds. Repeat this
operation 2-3 times.
The sharpener can slide along its seat (see picture 9) in
order to vary the sharpening angle. If the blade, after
various sharpening operations, has a chamfer (sharp
perimeter) with an excessive length (higher than 1.5 mm),
it is necessary to slightly move the sharpener away from
the blade. In order to do this, it is sufficient to slightly
loosen the screws without removing them, making the
sharpener slide toward direction “A”, and then tighten
the two screws again.

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 2­3 working days (see picture 10) when the machine is
used without interruption.

WARNING

The blade must never be dirty with grease or oil.

14. BLADE REPLACEMENT

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
key “1” and drift “2” locking the blade (shown in picture

11). In order to replace the blade, proceed as follows:

1) Use some protective gloves in compliance with the
Local Law of the Country where the machine is to
be used (use of personal protection devices);

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 “2” in hole “C” in order to lock the blade
(the hole in the blade must correspond to the hole
in the structure) (see picture 13).

4) Use butterfly key “1” in order to unscrew nut “D”
(see picture 13) and remove blade “E” (see picture 14).

5) Replace the worn blade with the new one “3”, 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.
