- INSTALLATION
The machine can work according to the parameters provided by the manufacturer if it is rightly installed and
the minimum requirements are observed, as follows :
- Machine must be used indoor and with temperatures from +5 to + 40 ° C.
- The relative humidity of the environment must not go over 95%.
- The nominal value of the voltage of electric energy must be between + - 10 and the frequency of the
nominal
value must be between + - 2%.
The floor of the building must be good leveled and it must have a good capacity too.
Floor space, distances and sources of energy are indicated in the following drawing.
The work table must be leveled: by using the screws + nuts put in the little feet holes, it is also possible to fix
the machine on the floor when necessary (for example when there are the connected features).
To grant the return of the coolant that goes onto the bars to be cut, we suggest you: level the work-table with
about 5 mm height each meters lenght to the unload side ( right side).
The enclosed electrical and hydraulic diagrams reproduce the necessary details to arrange the connections
that must be forseen for a requested power of 3 KW.
At the top of the supplying cables it is necessary to set up a sectionalizing device provided with a
protection particularly if it is equipped with the external VOLTAGE TRANSFORMER.
PROTEZIONE DIFFERENZIALE per i modelli dotati di variatore elettronico di velocità ( ESC )
Per inserire la protezione differenziale sulla linea di alimentazione è necessario utilizzare interruttori
con soglia di intervento sulla dispersione della corrente non inferiore a 300 mA ( consigliabile la
taglia 0.3 mA o superiore), eventulmente con la possibilità di regolazione del tempo (0>1.5 sec).
This machine has been foreseen for industrial and not for household use. In the event that should be
electromagnetic interferences the user is responsable for solving the problem together with the technical
assistance of the manufacturer. Before installing the machine the user must take into account possible
electromagnetic problems of the working area. In particular we suggest to install the plant away from:
- signalling, control and telephone cables;
- radiotelevision transmitters and receivers;

BAND CHOICE
In this paragraph we recommend the type of cutting band in accordance with the material to use . To get the
best performance from this machine it is necessary to undestand the right use and the limits of the used
tools .
The band to use must have the following sizes ( in mm. ) :
maximum lenght = 4150
minimum lenght = 4115
total height = 32 ( or 1 inch and 1/4 " )
thickness = 1,10
It is also important the band material , it is usually used the bi-metal band type in the different endurance
quality .
The standard types are named M2, M48, M42, M51.
The endurance of the teeth increases , and also the fragility, when going from the material M2 to M51.
For making a right cut it is also necessary to choose the pitch ( t ) or the number of the teeth per inch (z).
Usually the band must have the toothing as follows :
- close toothing - to cut thin materials, tubular and profiles.
- thin toothing- to cut solid materials or pieces that need a long band ( for example . the central part of a
profile " U " ), or softer materials as aluminium, copper, soft bronze.
By choosing the right one you can avoid a lot of working errors and you can get a good band penetration
and the necessary space for the chips.
If you cut some pieces at the same time, you must consider them as only one piece by considering the
global size.
The included table supply you the informations for a right choice, the same one can also be updated or
changed by the user according to his personal experiences.
Even if there are toothings with constant pitch , the most of the band sawing machines allow the use of band
with variable pitch toothing - groups of teeth with different pitch between them- that reduce vibrations and
noice, by getting better the finishing and the capacity of removal . This is the reason for which we give you
only the data concerning this kind of toothing..

9.4 - CONTROL DEVICES DESCRIPTION
The sectionalising device of the outer energy is :
On the left side of the control panel there is the main switch with interlocking attachment, pos-8/dr.RI0102
The control panel , drawing RI0102, placed in front of the operator includes the following :
1 - Main switch with interlocking attachment with thermo-magnetic overload protection of the all installation,
with releasing device for drop of current.-pos.8-.
2 - Emergency device ; it locks any electrical devices when connecting. To restore it, wheel the button 1/4 of
turning-pos.13-.
3- Control panel with display ( see paragraph KEYBOARD )
4 - Hydraulic regulator of cutting speed-pos.15-.
Other devices are placed in other same accessible parts.
5 - Main pressure regulator of the hydraulic installation -pos.5/dr.RI0085-
6- Manual opening/closing of front vice-pos.4/dr.RI0102-
7 - Unlocking/locking of turn saw frame for oblique cuts-pos.10/RI0102; read these cuts at the back grades-
pos.9/dr.RI0102-.
8 - Tap/taps of cooling circuit -pos.5/dr.RI0103- to proportion the liquid on the higher blade guide head , as
well as the main tap assembled on the recycle pump.
9 - Unlocking / locking of the higher sliding blade guide shaft -pos.16/dr.RI0102-.
10-Unlocking of the rapid stops for oblique cuts -pos.11/dr.RI0102 -.
11-Wall socket for synchronism with external gear -pos.17/dr.RI0102-.
12- Tension screw of the band -pos.2/dr.RI0102-.
9.5 - CUTTING SETTING
The assembled band allows the cutting of different material section , thanks to the variable pitch teeth ( little
teeth alternating biger teeth ) , but it is necessary to have the most proper band for the workpiece to get the
best of the machine.
Therefore please refer to the paragraph BAND CHOICE for a right use.
Put the work piece you have to cut into the vice by keeping a shake of 4/5 mm between the piece and the
jaws, necessary for the working of the automatic closing, then place it a little back as regards to the cutting
line.
Be sure that the handle -pos.10/dr.RI0102- blocks the rotation of the saw frame.
Push the main switch-pos.8/dr.RI0102-, restore the emergency device in case it is disconnected -
po.s13/dr.RI0102- , push the button OPEN ARROWS -pos.19/dr.RI0055 to close the vice and be sure that
the piece is correctly clamped in the jaws. If the manual closing of the lever -pos.14/dr.RI0102- is not
enough, the hydraulic cylinder of the vice slides behind and the cycle cannot go on.
Place the higher blade guide shaft so that during the cutting movement it does not knock against the
workpiece or the jaws, then lock it with the levers -pos.16/dr.RI0102-.
Wheel the speed regulator -pos.15/dr.RI0102- at 1 and push the button I -pos.20/dr.RI0055- START
CYCLE ; whatever the cycle may be stated, the machine makes the following :
Blade motor starting, slow cutting feeding, blade stop ( it can be excluded ), rapid return ( it can be excluded
) .
The piece approaching is excluded. The working stroke is automatically determined on the basis of the vice
opening, by further reducing the not productive working cycle
The choice of the most suitable cycle ( F1, F2, F3, coolant off ....... ) must be according to the working needs
.
Please refer to the paragraphs PANEL and POSITIONS PROGRAMMING OF CUTTING SAW FRAME.
9.6 - SEMIAUTOMATIC CYCLE
Set the material so that it goes over the cutting line, then lock it; select the blade speed, the functions, the
cooling distribution and start the cycle by pushing the button START CYCLE pos.20/dr.RI0055-. Adjust the
cooling flow that reaches the blade , start the cutting cycle by selecting the speed with the regulator device -
pos.15dr.RI0102.

At the cut end the motor stops, the blade goes back and the cycle finishes.Thanks to the electronic control,
the main described cycle can be changed depending on the working that must be done. For example by
putting in action the function F1-pos.26/dr.RI0055- the blade stops its rotation after going back to the
starting point; by putting in action the function F3 the blade locks and the saw frame movement stops in
cutting end position.
9.7 - ESC WORKING = Electronic Speed Control
The electronic inverter allows to continuously change the revolutions per minute of the blade motor. By
using the two motor speeds you can get two speed range ( MEDIUM LOW SPEED and MEDIUM HIGH
SPEED ) that allows a better blade using by adjusting it to the workpiece.
With the motor in operation , increase or reduce the speed only by pushing the button ( +/2 )=13/dr.RI0055
or ( -/1 ) = 11/ dr.RI0055 till you read on the display the desired speed value in m/1'- .
9.8 - LOCKING DEVICE / EMERGENCY LOCKING
At any time it is possible to stop the cycle:
- By pushing the button 0 - STOP CYCLE-pos.21/dr.RI0055- the machine stops immediately, but anyway
there is the possibility to use the other keys, for example to change the cycle type or blade speed ;
- By pushing emergency key -pos.1/dr.RI0055- the cycle stops immediately and it is not possible to push
other keys before having restored it.
- By pushing the main switch-pos.8/dr.RI0102- you turn off the current of the machine ;
In case of current braking, the sectionalising switch-pos.8/dr.RI0102 goes on 0 position and it is necessary
to restore it to start the machine again.
9.9 - SAW FRAME ROTATION FOR OBLIQUE CUTTING
It is possible to make cuts from 45° left to 60 right by keeping the locked piece nearest as possible the
cutting line from the both sides.
Furthermore the blade penetration is always perpendiculary to the material surface, except during the cuts
with the saw frame lower till 5 deg.
For the oblique cuts it is necessary that no material is cmapled into the vice, loosen the lever-
pos.10/dr.RI0102-, wheel the handle -pos.11/dr.RI0102 - in the clockwise sense, and swivel the saw frame
manually ( by using the handle of the sliding side vice ) till you read on the scale -pos.9/dr.RI0102- the
desired angle. The automatic stops drived by the handle -pos.11/dr.RI0102- makes easy the positionning on
the angles of 0 and 45 deg. right/left.
Before going from an angle to another be sure that the parts to wheel do not knock against the jaws or the
workpiece that must be clamped into the vice.
Thanks to the structure balancing , the rotation of the saw frame is never difficult.
9.10 - SAW FRAME INCLINATION ( FOR LOWERING CUTS TILL 5 DEG. )
For cutting profiles and solids that have very heigh vertical body ( over 250 mm ) it is suitable to low the saw
frame as regars to the vertical ( max.5 deg. ) to get a better surface penetration. It is necessary to loosen the
screws -pos.3/dr.RI0104- and pos.2 and 3/dr.RI0105 - with the same spanner of the band tension, then use
the grub screw-pos.12/dr.RI0105- at the end of the displacement lock hardly the screws previously
loosened .
Then it is necessary to replace the thiner closing jaw with the closing jaw of big thickness .
When the saw frame is lower , it is necessary to set a new position of " stroke end of band return " by
displacing the feeler -pos.2/dr.RI0104- in a behinder position. ( The stroke end -pos.1/dr.RI0104- locks that
the band back knocks against the support of the tempered bearing jaws -pos.4/dr.RI0106-) You must make
this operation by loosing the screw-pos.4/dr.RI0104- and by taking the feeler off -pos.2/dr.RI0104- some
milimeters ( from 3 to 10 about ).
Check the adjustment results by moving the saw frame to and fro with the buttons -pos.16 and 17- of the
control panel -dr.RI0055-; the back of the band must not knock against the support-pos.4/dr.RI0106- and the
teeth must be at 4 mm. about rear to the bearing jaws plane .
9.11 - SUPPLEMENTARY VICE FOR CUTTING BIG PROFILES (optional).
This attachment has to be used in addition to the normal vice when big profiles must be cut , as illustrated by
the dr.RI0106.
