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.

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
3
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.

14. LUBRICATION
Every 3-4 working hours, 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 electric
scissors and fill it with the grease supplied. Screw plug
“A” again a few turns. Screw plug “A” a few turns every 2-
3 working hours (see figure 11).
The blade must never be dirty with grease or oil.
WARNING A
If the blade is no more able to cut (even after repeating the
sharpeningoperationseveraltimes)it isnecessarytoreplace
it. In order to carry out this operation, use butterfly wrench
“1” and drift “3” locking the blade (shown in figure 12). In
order to replace the blade, proceed as follows:
1) Use some protective gloves in compliance with
Italian Legislative Decree 81/08.
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 figure 13.
3) Insert drift “3” (see figure 14) in hole “C” 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
“D” and remove blade “E” (see figure 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 its sharp side (the one 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.
