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.

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 fixture is sold.

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 relative necessary information.

The cutting unit works also 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.

Do not carry out 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 possible to assemble cutting unit FP861A2 on machines O.E.M. only if their original

structure is not modified. Otherwise, the intervention must be certified by Rasor®.

10. INSTALLATION AND USE

To install and use the cutting unit do as follows:

1) Fix the cutting unit to the machine by means of a flat or

angle bracket to mount on the upper part of the motor

support of the unit.

NOTE

The cutting unit can be installed in any position or angle: vertical,

uside down, lateral. The aluminium base does not have to touch

the machine table.

2) Lay down the material to be cut;

3) Connect the air hose to quick connection “A” (not supplied)

(see picture 3);

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

5) Put the material on the cutting base (see picture

4);

6) Adjust the moving front protection according to the

thickness of the material to cut;

7) Enable the air remotely and carry out the cutting

operation.

NOTE

It is possible to use cutting unit FP861A2 both keeping it

fixed and making the material slide and viceversa. It is

important to keep the material to cut as stretched as

possible to prevent it from curling.

NOTE

Cutting unit FP861A2 is provided with a simple anchorage

flange, by means of which it can be fastened on fixed or

automated brackets (see picture 5).

WARNING

Do not use the two bolts which connect the motor

to the cutting part to fix cutting unit FP861A2,

otherwise the motor shaft could break. In this case

the warranty will be void.

11. AIR PRESSURE GAUGE (OPTION)

The cutting unit 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 as option.

The unit shown also in picture 6 is made up of:

1 - pressure reducer;

2 - valve to drain the condensate;

3 - drip-feed oiler unit;

4- oiltank;

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 scissor.

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

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.
