4. PRODUCT DESCRIPTION

This manual describes electric scissors model OPTIMA 702 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 supporting front foot and of an effective cutting system with quadrangular blade, it is possible to use the electric scissors to cut different materials. In particular the scissors have been designed to cut difficult materials such as moquettes, polymeric materials, fiber glass, insulations and leather (even hide).

One special feature of electric scissors OPTIMA 702 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 immediately start cutting again. A high power motor, perfectly balanced, with a high number of revolutions and totally free of maintenance, reduces the vibrations to the minimum. For this reason the electric scissors comply with Legislative Decree no 187 dated 19/8/2005, which adopts European Directive no 2002/44/EC concerning the risks deriving from mechanical vibrations. The mechanical parts are made of high-quality steel, bronze and aluminium and require lubrication after several working hours.

Page 8

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 device is sold.

· It is STRICTLY FORBIDDEN to smoke during the installation or adjustment operations of the electric 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 relative necessary pieces of information.

· The electric scissors work 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.

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

· Always pay attention to the electric cable position to prevent it from being cut or damaged by the blade.

· It is allowed to assemble electric scissors OPTIMA 702 on machines O.E.M. on condition that their original structure is not modified. Otherwise, the intervention must be certified by Rasor®.

9. RESIDUAL RISKS

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

L At the end of the working operations, the motor could be very hot. L The cutting blade can work even when the protective device is disassembled.

Page 9

10. USE

To use the electric scissors manually, proceed as follows:

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

2) Connect the scissors to the power supply;

3) Put the material on the cutting foot;

4) Enable the enabling push button (see picture 3);

5) Push the electric 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 electric 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 “A” in picture 4).

11. MOTOR FUSE REPLACEMENT

In order to replace the motor fuse, proceed as follows:

1) Disconnect the scissors from the power supply;

2) Remove the screw from the fuse cover (see point “A” picture 5);

3) Take out the glass fuse by means of the proper pliers supplied (see picture 6);

4) Verify its integrity (see picture 7) and, in case, install a new fuse checking the correct amperage;

5) Close the cover and tighten the screw.

WARNING

Never use the scissors when the fuse cover is open. Risk of electric shock.

Page 10

12. REPLACEMENT OF THE MOTOR BRUSHES

Electric scissors OPTIMA 702 are provided with a high power permanent magnet motor and torque. For this reason it is necessary to check periodically if the carbon brushes are worn in order not to jeopardize the motor operation and its duration period. Unscrew the caps located on the cover by means of a slotted screwdriver

(see picture 8); withdraw the carbon brushes, check if they are worn and, if needed, replace them. Assemble the two caps again,

being careful to hold them in a perfectly vertical position, and screw them completely only when you are sure that the mouth is the correct one.

Note: The brush must be inserted with its black part directed inside the motor.

Note: A slight difference in the wear of the two brushes is absolutely normal in a permanent

magnet motor. Nevertheless, in the event that the difference between them is excessive, it is necessary to apply to a technical center for a complete check of the fixture.

WARNING

Before carrying out any operations on the electric scissors, make sure that the supply plug is not connected to the mains.

13. BLADE SHARPENING

After many hours of a continuative use of the electric 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 sharpening button “1” for 3-4 seconds (as shown in picture 9). Repeat this operation 2-3 times.

If the sharpening process should be ineffective, check the wear of the emery grinding wheel “2” (see picture 9). If wheel “2” is too worn or dirty, replace it by removing the blade with the proper tool.

WARNING

The sharpening button can be only pressed if the front mobile protection is completely lowered.

14. LUBRICATION

Every 3-4 days of use, it is necessary to lubricate the pair of gears. To carry out this operation, remove protective plug “A” located on the head of the electric scissors and fill it with the supplied lubricating grease. Screw plug “A” again few turns. Screw plug “A” some turns every 2-3 working hours (see picture 10). Fill the plug again, once it has been tightened.

WARNING

The blade must never be dirty with grease or oil.

Page 11

15. 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 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 the safety back fixed protection “A” (see picture 12), by unscrewing the two slotted screws “C” by means of a screwdriver (not supplied by the manufacturer) as shown in picture

13.

Remove the safety front mobile protection “B” (see picture 12) by unscrewing pin “D” and by extracting the two washers “E” as shown in picture 13.

3)Insert drift “3” (see picture 11) into hole “F” 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 “G” (see picture 14) and remove blade “H” (see picture 15).

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

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