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. spreaders, computerized cutting). FP120DT can operate

continuously and it can cut at various heights by means of multiple installation. Thanks to the

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 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, 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 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.

6. NOISE LEVEL

NOTE

It is advisable for cutting unit FP120DT owners to verify the compliance with the local standard

concerning safety at work. The use of ear protecting devices is compulsory.

The maximum acoustic pressure level emitted by cutting unit FP120DT is about 60dB (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).

Cutting unit FP120DT has been designed, manufactured and assembled to cut any kind of

fabrics or materials, with the exception of metal 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 metal and wooden materials.

It is forbidden to use cutting unit FP120DT for purposes different from the above-

mentioned ones.

9. RESIDUAL RISKS

Even though the cutting unit is safe, operators must pay attention to preserve their safety

and that of others.



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

8. USE WARNINGS

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

•All the operations must be carried out complying strictly with the safety rules of the

country where the device is to be installed.

•It is STRICTLY FORBIDDEN to smoke during the installation or adjustment operations of

the cutting unit.

•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 cutting unit works even without its safety protection device. This protection

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.

•Do not perform any adjustment while the blade is working.

•Always pay attention to the air pipe position to prevent it from being cut or damaged

by the blade.

•It is allowed to assemble cutting unit FP120DT on machines O.E.M. on condition that

their original structure is not modified. Otherwise, the intervention must be certified by

Rasor®.

•The (inside) air pipe and connector diameter must be min. Ø 8 mm.

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 an air pipe to the quick connection “A” and an air pipe to the quick connection

“B” (not supplied) in order to carry out a bidirectional cut (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 in one direction or in the opposite one.

NOTE

Cutting unit FP120DT 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.

11. AIR PRESSURE GAUGE (OPTION)

The cutting unit must be necessarily supplied 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 8 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 toconnect the quick connection to the network;

8 - pipe fitting to connect the quick connection to the

cutting unit.

For the use and maintenance read the instruction sheet supplied with

the filter.

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.

14. PNEUMATIC MOTOR

In case of technical problems with the pneumatic motor, the entire motor must be

sent to Rasor®. Never disassemble the pneumatic motor since it could jeopardize

the guarantee.
