4. PRODUCT DESCRIPTION

12 7

The fixture described in this manual are electric scissors model DS503MT which are used in

order to quickly cut composite materials, in particular the fiber glass. They are extremely

versatile, light and precise in the cutting operation. Thanks to the use of a thin foot and an

effective cutting system with heptagonal, circular or decagonal blade, it is possible to use the

electric scissors for the precise trimming of molds, stuffed materials, leathers and laminated

materials. One special feature of electric scissors DS503MT 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 electric scissors DS503MT are extremely light (they weight only 900g) and handy and

allow carrying out quick and precise cuts, even with curve profiles. A high power motor,

perfectly balanced, with ahigh number of revolutions and totallyfree of maintenance, reduces

the vibrations to the minimum. For this reason the electric scissors comply with European

Directive No. 2002/44/EC concerning the risks deriving from mechanical vibrations.

The mechanical parts are made of high-quality steel and bronze and require lubrication after

several working hours.

6. RUMOR LEVEL

NOTE

It is advisable for electric scissors 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.

The maximum acoustic pressure level emitted by electric scissors DS503MT 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).

Electric scissors DS503MT have been designed, manufactured and assembled to cut every

kind of fabrics or materials, 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;

- on wet or damp materials;

- to cut plastic, metal and wooden materials.

It is forbidden to use electric scissors DS503MT for purposes different from the

above-mentioned ones.

9. RESIDUAL RISKS

Even though the electric scissors are safe, operators must pay attention to preserve their and

other people’s safety.



At the end of the working operations, the motor could be very hot.



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

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 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

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 DS503MT on machines O.E.M. on condition

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

by Rasor®.

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 figure 4).

11. MOTOR FUSE REPLACEMENT

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

1) Disconnect the scissorsfrom the powersupply;

2) Remove the screw from the fuse cover (see

point “A” figure 5);

3) Take out the glass fuse by means of the proper

pliers supplied (see figure 6);

4) Verify its integrity (see figure 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.

13. EMERY GRINDING WHEEL ADJUSTMENT

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 emery grinding wheel

“2” on the blade itself (by means of push button “1”, as

shown in figure 9) for 3-4 seconds.

Repeat this operation 2-3 times.

The emery grinding wheel can slide along its seat (see

figure 10) in order to vary the sharpening angle. If the

blade, aftervarious sharpening operations, hasa chamfer

(sharp perimeter) with an excessive length (higher than

1.5 mm), it is necessary to slightly move the emery

grinding wheel away from the blade. In order to do this,

it is sufficient to slightly loosen the screws without

removing them, making the emery grinding wheel slide

toward direction A, and then tighten the two screws

again.

12. REPLACEMENT OF THE MOTOR BRUSHES

Electric scissorsDS503MT 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; 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.

Before carrying out any operations on the electric scissors, make sure that the supply plug is

not connected to the mains.
