3 - MACHINE NOISE
The noise level of the working area - given the conditions described below - is determined by the
simultaneous working of several parts of the machine in motion (according to the working cycle), in
addition to the tool when cutting the material.
The noise level is detected in different moments, corresponding to different working phases. The
proper device is placed about 1 meter near the machine and about 1,60 m above the floor. The
results of each test is in dBA and they are the average of 3 tests made from the left side,
opposite side and right side.
For any machines the working conditions are the following:
When idle, at the maximum blade speed: dBA 63
During the cut, at a suited blade speed, cutting solid steel (St12=≈C20, 50 mm diameter): dBA
75
(tolerance ± 2dB).
In the standard production the test is made on a machine like this, in compliance with E.C. safety
norms 2006/42/CE and EN13898. Using the saw in bad conditions or using wrong tools causes
significant alterations of these tests and it jeopardizes the health of the staff and the good results of
the work. Useful is the European Guideline 2003/10/CE.
The noise depends mostly on the cutting material, on its size and on the clamping. Considering that
the above mentioned decibels could be exceeded, we recommend the operator to use personal
protections (headsets, plugs, and so on) when working for a long time with high noise levels.
3.1 - ADDITIONAL HEALTH AND SAFETY REQUIREMENTS
The machines manually controlled by an operator during all work phases must comply to further
health and safety requirements as specified by article 2.2 of the Annexed I of the European Directive
2006/42/CE and following integrations. In particular, the level of the machine vibrations when working
must be clearly specified in the instructions.
This machine does not produce vibrations higher than 2.5 m/s2
The measurement procedure is in compliance with the general norms applied to this type of
machinery.
As in the previous paragraph, using the machine in unsuitable conditions or using the wrong
tools can cause changes affecting this value, causing a risk to the health of the working staff
as well as the quality of the production. Useful is the European Guideline 2002/44/CE.
Vibrations produced during the cut may be amplified by the material, by its dimensions and
its positioning/clamping in the vice.

RABGBC - Loading mounting bracket, to connect the loading side of the machine to one of these two roller tables:
Loading Roller Table –RTS230/60C1 - To install them rightly, it is necessary first of all to level the machine’s work
table. To level and line up the loading roller table refer to the work table and to the supporting back jaws. It is 1 meter
long and has 3 rollers 50 mm diameter, 280 mm length. Take as reference point the worktable and the support back
jaw in order to aligne the roller tables starting from the one that is nearest to the machine.
Modular roller tables RTSPRW30 - RTSSEW30 - To install them rightly, it is necessary first of all to level the machine’s
work table. To level and line up the loading roller table refer to the work table and to the supporting back jaws. They are
2 meters long and has 7 rollers 50 mm diameter, 280 mm length. Predisposed to be connected themselves for a
loading line of 4 , 6 meters and more. Take as reference point the worktable and the support back jaw in order to
aligne the roller tables starting from the one that is nearest to the machine
Minimal lubrication system –This device, applied to the saw, allows to eliminate almost completely the traditional
coolant system, keeps the material much cleaner and avoids to waste cutting oil and water. It works only during the cut.
It is comprised of a nozzle - 1/RI0463 - with micro-holes, a tank with devices to adjust the quantity of oil and the air
pressure. The switch of the electric system - working with low tension 24V AC - allows to turn it off at any moment and
use the normal coolant system

10 - 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 of the used tools and what you have not to do
with them. The band you have to use must have the following sizes ( in mm. ) :
maximum lenght = 2460 minimum lenght = 2440 total height = 27 thickness =0,9
It is also important the material of the band , it is usually used the bi-metal band type in the different HARDNESS quality,
named M42 or SVGLB The endurance of the teeth increases , and also the fragility, when pass from the material M2 to
M51.
To 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.

In case of a lack of precise indications (for example, norm ISO 8995) for special areas, we advise to supply a lighting
equal to 750 LUX.
12 - MACHINE DESCRIPTION, E.C. SAFETY NORMS, PROPER USE
Band sawing machine . The head swivels from 0 deg. to 60 deg. left to obtain square or mitre cuts of metal profiles and
solids. The Autocutl make possible autonomous cuts by gravity feed.
It is not suitable to cut wood and assimilated materials (cfr. D.M. 2006/42/CE, enclosure I, paragraph 2.3).
All manual works consist of : locking material, approaching and cutting , tool return, unlocking material and bar
displacement for a new cutting.
The starting of the tool is controlled by the pushbutton inside the handle, which has a safety guard against unintented
start-up.
In designing and manufacturing this machine, we have considered the requirements of the Machine Directive, important
document valid in all E.E.C. Countries. Furthermore we have considered the norms as type A and B in the case that
specifications of type C are not available.
From the working position, in front of the frontal vice, the operator has the possibility to actuate the controls and to control
the good working of the machine.
In the other paragraphs you will find any informations to use the machine in the best way and for a very long time.

13 - MACHINE SETTING FOR STARTING
Verify that the machine has not clear damages or faults and check upon the standard equipment that includes the tools,
fittings to carry out some adjustments, using and maintenance handbook.
In case the machine is supplied with additional equipment make sure that it is adaptable to the machine.
Point in good time the possible damages or faults to the reseller or to the service staff before start-up the machine.-
Remove the lock flask between saw frame and base.. The protective sustances put on the surfaces to protect the
machine during the moving and transport must be cleaned by a non-filamentous clorth or paper, please check that there
is no rust on the metallic parts.
In case of using compressed air jet always wear proper eye protection.
Remove the possible dirty that can obstruct the passage of the coolant along the coolant hoses.
The parts in motion ( band guides, trolleys, pivots, bearing support, bearing disc etc. ) are already lubricated, the reducer
gear holds the exact quantity of oil necessary to the operation because it is a LONG_LIFE construction type.
13.1 - COOLING SYSTEM
Prepare the cooling by mixing the cutting oil and water ( the tank holds about 15 litres ) in proportion of 1/10, 1/15 or
according to the instructions of the supplier of the product. Pour out some coolant in the tank or directly on the base . In
each case keep attention that cooling does not come out of the base or on the coolant pump motor.

13.2 - ELECTRICAL CONNECTION
Verify that the voltage and the power frequency are compatible with numbers reported in the technical data plate ( it is
placed on the right side of the floor stand ) a difference over 10 % causes some working unevenness more or less
manifested.
Saw frame of GH models can’t be pulled down without electric supply.
The supply cable has already a CEE plug.. If you have to replace it with the one of normal use, we suggest you to
let do this operation to specialized persons (for example to electricians).
The phasing performed by the manufacturer allows to get a right rotation of all motors by connecting the wires
in the following order L1=R, L2=S, L3=T, anyway check as follows: (Band protection carter rightly closed )
a) insert plug into electric wall socket ( and switch on the main switch) the GREEN light that controls 24V line supply,
closed blade carter and blade tension must be flashing.
if this does not happen it is necessary to tension the band according to the instructions of the following
paragraph.
b) turn the motor speed selector on 1 or 2
c) push the button placed inside the handle of the control lever (for GH models turn the mode selector on MANUAL
before the push button)
d) check that band moves; the direction indicated by the arrow printed on the carter -5/RI0377- shows the right
movement.
(if not , after switching off the machine, disconnect the line plug, reverse the connection of two of the connection wire,
excluding green/yellow cable of grounding and start again from point a).
e) be sure that coolant is sucked in by the tank and it arrives in the cutting area, while motor is running and cooks are
opened –RI0384-
h) stop the working by leaving the handle switch
14 - BAND TENSION
The machine is equipped with a tensioned blade ( and the starting of the motor is impossible if right force of
tension has not been adjusted before) .
After switching on the machine, if GREEN light of control box is not flashing, it means that you must tension the band:It is
necessary to screw the screw -3/RI0385- by using the hexagon key until the light flashing and screw again for 1/4 of
tourning.

It is better to check if blade is well mounted and so: open the carter hinges and remove them from the supports -1/RI0376
by ensuring that the back of the blade is against the pulley -3/RI0377- and it is correctly mounted into the band guides -
2/RI0377-. If necessary untighten the screw of the band tensioner -7/RI0597-a little, place the band better and
reassemble the carter and be sure that safety microswitch -2/RI0376- is rightly pushed by its key.
After switching on the machine, if GREEN light of control box is not flashing, it means that you must tension the band:
It is necessary to screw the screw -7/RI0597- by using the hexagon key until the light flashing and screw again
for 1/4 of tourning.
The procedure to change the blade after a change of pitch, wear and tear, and break is the same one of the above
described procedure. In this case it will be necessary a careful cleaning of all points of connection with the band.

-GREEN light (controls of band tensioner, blade protection carter and 24V low tension circuit) -2/RI0598-
motor speed selector –3/RI0598-
The Autocut model control box includes aforementioned devices and more:
-mode selector –4/RI0598- with 3 position:
a) manual cut ; left side
b) autonomous cut with gravity adjustable feed autocut; middle position
c) impulse lowering for fast approach without cut; right side
-hydraulic down-feed regulator . –5/RI0598-
15.1 - CUTTING SETTING
The standard blade allows to cut different sections of material, thanks to the variable pitch of the toothing (
alternating little teeth to big teeth ) but it is necessary to have the most suitable blade for the workpiece giving
the possibility by making the most of the machine.
Therefore see the schedule - BAND CHOICE - for a right use.
Turn the frontal lever for rapid locking –4/RI0597- to the right side, and open the vice by turning the front handwheel –
5/RI0597-.counterclockwise.
Place the workpiece ( that you have to cut ) on the worktable by keeping 3 or 2 mm between the piece and the jaw, this is
necessary for a better using of rapid closing ,and place it rightly according to the cutting line .
Be sure that the handle –13/RI0597- locks the rotation of the work table.
Lock the workpiece between the jaws by rotating the lever 4/RI0597- and check if piece is well locked.
Place the sliding bar of the blade guide holder –9/RI0597- so that it can not knock into the workpiece or into the jaws
when saw frame coming down.
Switch on the machine, choose the motor speed 1 or 2 with the selector and push the start pushbutton inside the
control handle , adjust the cooling flow on the blade and start the descent for the cutting, by keeping a regular, constant
movement . At the end of the cut. Switch off the motor rotation with handle control lever.
On Autocut models saw frame goes down manually only if selector is on MANUALposition,
goes down automatically if selector is on central position, stated as “autocut”: during lowering adjust feed rate into
material by the proper regulator.
At the end of the cut, blade movements stops by a microswitch: lift-up the saw frame until the cutting start position, for
the next cut.
This version allow to begin the cut like a normal manual saw and then to continue automatically –the sawframe drops
thanks to the gravity –or always manually till the cut is completed.

To get the most out of the versatility of this saw the operator has to adjust the loading springs - pos. 3/R10595 - along
their slot –1/RI0595- depending on the cut requirements :
- positioned in the upper part of the slot means more down-feed pressure and therefore more penetration of the blade
into the material (the sawframe will be heavier to lift)
- positioned in the lower part of the slot it works like a normal manual machine, allowing the user to lower/raise the
sawframe easily
- the middle position is a compromise between downfeed force and easy handling. Normally this is the standard position
To move the springs easily along the slot it is advisable to do the following (with power on, blade speed = 0):
-unlock the screw –2/RI0595- ,lower the sawframe manually so that the springs move up, and lock the same
screw again
or
-unlock the screw –2/RI0595- , raise the sawframe manually to move the springs down and lock the same screw
again.
At the end of the cut the user has to lift the sawframe manually.
15.2 –STOP- EMERGENCY STOP
The cutting cycle can be stopped at any time:
- by releasing the button inside the handle all electric devices stop immediately
-by turning off the main switch –1/RI0598-- equipped with RED emergency button
-by disconnecting the power supply
- by opening the blade guard a safety micro-switch –5/RI0051- stops all drivers and the saw is turned off.
15.4 - HEAD ROTATION FOR OBLIQUE CUTTING-
To make these cuts it is necessary to unlock the lever –13/RI0597- , turnl the saw frame manually until you read on the
scale the desired angle then lock the lever –13RI0597-. again. Predetermineted lockings –12/RI0597- makes easier on
the positions 0 deg., 45 deg and 60 deg.

.
When moving from an angle to another it is recommended to not have material on the worktable and/or clamped
by the vice.
The worktable at the right side of the blade is equipped with 4 groove for the blade angles of 15, 30 45 and 60 degrees
15.5 - OVERLOAD PROTECTIONS
The motor is protected against overheating thanks to bi-metal thermo-protectors which stop the control circuit and the
blade.
To start working again, the temperature must have dropped below the maximum limit allowed.
In the meantime try to remove the causes that led to the overheating, for example the blade is entrapped in the material,
the cutting speed is too high, oil is missing in the gear box, and so on.
16 - ADJUSTMENTS ( with machine switched off)
VICE- Guide Adjustment by means of nuts and screw - When the vice is almost completely open, loosen all nuts on
the left side and, starting with the first 3 screws tighten them more strongly.(these 3 are the screws that are aligned with
the fixed part of the vice) and lock them with the nuts. Close the vice and adjust the remaining 3 screws, because they are
now aligned with the fixed part ot the vice. Verify the result by opening and closing repeatedly the vice, repaeting if
necessary..
BLADE - adjustment of the band guides because of band thickness variation:
This adjustment must be done when you hane a band with thickness different from 0.90 mm or in case the hard metal
pads of the band guides are used up because of used for a long time. The easiest test is the following: use a right piece a
band, and after blunting the teeth, put it in the band guides and let it slide for more times for checking the kind of gap.
Following to the obtained result do as follows: unscrew slightly the two lower screws, and with the right piece of band
inside, press by hand and tighten the two screw.
Check that tha gap is not excessive (max. 0.02 or 0.03) and make sure that the both screws are well locked; otherwise
tighten it a little bit more. Repeat within other band guide.
The side pads are mechanically fixed and they can be replaced singly, without taking out the band guides from the
machine, by unscrewing completly lower screws; if you take out both side pads you can take out the upper bearing .
