4. PRODUCT DESCRIPTION
The fixture described in this manual is a cutting unit model GRT10L which can be assembled
on automatic machines (e.g. spreaders, computerized cutting) by means of proper holes
located in the motor support. GRT10L can operate continuously and it can cut at various
widths by means of multiple installation. By cutting with the blade and the counterblade
always in contact and thanks to the steel upper quality of the blade supplied, GRT10L
guarantees the clean separation without frayings of the two borders of the cut material.
The three-phase motor with extremely compact dimensions and extreme reliability with
100 mm diameter blades, guarantees cuts with thickness up to 3.5 cm. Asharpenerassembled
on the cutting unit head allows sharpening the blade at any moment without disassembling it.
After carrying out this operation, it is possible to 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, thus making the cutting unit comply with Italian Legislative
Decree No. 81 dated 9/4/2008 “Testo Unico sulla Salute e Sicurezza sul Lavoro” (Consolidated
Act on Health and Safety at Work), Title VIII - CHAPTER III (worker protection from
mechanical vibration risks). The mechanical parts are made of high resistance steel, bronze and
aluminium and require lubrication after several working hours.

8. USE WARNINGS
Firstly make sure that the lines are able to feed the cutting unit correcltly, in
compliance with the safety rules (for the feature required see par. 5).
We suggest installing a magnetothermic safety device before the cutting unit and check
that the ground circuit is effective. Before working on the feeding cable pull the plug out.
Check that electric connections and protections correspond to the driving force and the
plate data values (voltage and current), required by the different electric circuits.Byreferring
to the CEI 11-27/1 standard all the works carried out by means of electric current must be
performed by a staff, who has been provided with all the devices required by the above-
mentioned standard. For the works carried out under voltage, it is necessary that the
employer certifies the suitability, against formative processes.
The cutting unit GRT10 is supplied with electric cable connected
to the connector block located beside the motor.Theuser
must connect the cutting unit to the mains (the cable complies
with the CEI 20-22 III Standard). Never change the length of
the cable supplied. If it is necessary, use a longer cable and
replacetheonesupplied

11. INSTALLATION AND USE
Even though the cutting unit is 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.
To install and use the cutting unit manually, proceed as follows:
1) Fix the cutting unit on level squares or angles by means of four 5MA screws, by inserting
them in the four holes located in the motor lower cover (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 compulsory for the Teflon base to touch the machine table.
2) Lay the material to be cut;
3) Connect the cutting unit to the electric feeding;
4) Put the material on the cutting foot;
5) Adjust the front mobile protection according to the thickness of the material to be cut (see
picture 6);
6) Carry out the cutting operation.
NOTE
Cutting unit GRT10L can work in a fixed position (the material has to be moved) 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.

(yellow-green cable). Possible faulty earthing connections may cause unsafe working
conditions. Possible damages are not at RASOR®s.r.l. charge.
The electric feeding must be supplied by a line protected against overcurrent by means of
the automatic switch (magnetothermal) or delayed fuses with a suitable dimensions. The
current of the safety devices must be as low as possible considering the max. absorption of
the machine (see identification plate).

WARNING
The operator must arrange a disconnetting switch on the supply line in order to switch off
the machine, if necessary.
WARNING
Never use the two bolts which fix the motor to the cutting part to fasten cutting
unit GRT10L. This operation may cause the motor shaft to break. In this case,
warranty is not valid.

12. BLADE SHARPENING
13. LUBRICATION
Every 3-4 working days, it is necessary to lubricate the
pair of gears. To carry out this operation, remove
protective plug “A” located on the motor support of
the cutting unit and fill it with lubricating grease Rasor.
Screw plug “A” again few turns. Screw plug “A” some
turns every 3-4 working days (see picture 9).
9
A
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 sharpen the blade. To carry out this
operation, start the blade and press sharpener “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.

If the blade is no more able to cut (even after repeating
the sharpening operation several times) it is necessary to
replace it. To carry out this operation, use wrench “1”
and drift “3” locking the blade (shown in picture 10).
To replace the blade, proceed as follows:
1) Use some protective gloves in compliance with
Italian Legislative Decree 81/08;
2) Remove the mobile front safety protection “A” (see
picture 11) by unscrewing pin “C” and removing
the two washers “D” as shown in picture 12.
Remove the fixed rear safety protection “B” (see
picture 11) by unscrewing the two cross screws
“E” by means of the proper screwdriver (not
supplied by the manufacturer) as shown in picture
13.
3) Insert drift “3” into hole “F” (see picture 14), so
as to lock the blade (the hole on the blade must
correspond to the one on the motor support).
4) Use wrench “1” to unscrew nut “G” and remove
blade “H” (see picture 14).
5) Replace the worn blade with the new one “2”,
being careful to center the blade on the gear, in
the correct position, and remember to assemble it,
so that the Rasor writing can be seen by the
operator.
6) Assemble all the components again and carry out
the sharpening.
