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, 80mm 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.

Some of these devices are suitable for BS 350 Gh as for BS400 GH. Some other like roller tables and
connections are NOT INTERCHANGEABLES.
Here the common devices or optional :
Inverter for variable blade speed - ESC - is an accessory which can be installed when manufacturing the
saw and allows the blade to have a variable speed. It can be adjusted by means of a selector located on the
control panel.
In case the maximum power supply threshold is exceeded - for example, because of an excessive cutting
pressure or because the blade remains stuck into the material - the inverter stops the motor. To restore it, the
main switch has to be turned to 0 (OFF), wait for about one minute and then turn it on I (ON).
In the meantime, try to find out the reason that caused the interruption and eliminate it.
Minimal lubrication – THE MINIMAL LUBRICATION SYSTEM APPLIED TO THE BANDSAW ALLOW TO
ELIMINATE ALMOST COMPLETELY THE TRADITIONAL COOLANT SYSTEM. THE MATERIAL IS MUCH
CLEANER AND THERE IS NO WASTE/SPILLING OF COOLANT AND WATER, CONTRIBUTING THUS

10 - BAND CHOICE -
In this paragraph we recommend the type of band to use for cutting an accordance to material that must be
worked. To get the best performance from this machine it is necessary to understand the right applications of
the used tools and what you have not to do with them.
The band you have to use must have the following dimensions (in mm.):
Standard feature for BS350 GH = 3370 x 27x 0,9
maximum length = 3380 minimum length = 3360 height = 27 max. thickness = 0,90
Standard feature for BS400 GH = 4020 x 34x 1,1
maximum length = 4030 minimum length = 4010 height = 34 max. thickness = 1,10
It is possible to use bands with a different thickness by changing appropriately the width of the pads guide “vv”
(see the paragraph ADJUSTMENTS ) and the tensioning of the band. It is also important the material of the
band; it is generally used the bi-metal band in different endurance qualities. The standard types are named
M2, M48, M42, M51.
The endurance of the teeth increases - and the fragility too - by going from the materila M2 to the M51. There
are also blades with hard metal pads or with diamond dust.
For making a right cut it is necessary to choose the pitch (t) or THE NUMBER OF TEETH PER INCH (z).
The blade must have generally the toothing as follows:
- close toothing for cutting thin materials, tubular and profiles.
- thin toothing for cutting solid materials or pieces that need a long piece of band (for example the central part
of a profile "U" ), or for cutting softer materials as aluminium, copper, soft bronze.
By choosing the right one you can avoid a lot of working mistakes and you can get a good blade penetration
and the necessary space for the chips.
If you cut more pieces at the same time, you must consider them as one piece (that is you have to
consider the global size).
The enclosed table shows the necessary information for a right choice. It can also be updated or changed
by the user according to his personal experiences.
Even if there are toothings with constant pitch, most band sawing machines allow the use of bands with
variable pitch toothing - groups of teeth having different pitch one from each other, that reduce vibrations and
noise and improve the finishing and the capacity of removal.

11. INSTRUCTIONS FOR USE AND WARNINGS
This machine can make automatic work cycles, however at the end of each one the operator has to remove
the material that has been cut and possibly change the cutting conditions. Therefore the saw sometimes
must be manually adjusted and then it works in automatic cycle (so the operator is not indispensable).
The working cycle ends when the machine stops; in order to begin a new cycle, the starting procedure will
have to be repeated.
This machine is designed and manufactured so as to be safely used by the operator, provided that it is
properly operated . No protections will ever suffice if the operator does not work with due
caution, does not make sure that the machine is in top operating conditions and does not
follow the instructions below.
You must remember that the machine is designed to CUT METALS with a sharp tool, and you
are responsible to see that it is operated in a SAFE and CORRECT manner.
1. make sure that the machine is properly installed and electrical installation is proper.
2. be sure you are familiar with all operating, safety, and applications information before
running this saw.
3. see that all who operate this machine are properly trained and fully aware of all safety
practices.
4. do not expose yourself or other people to any risk.
5. insist on proper personal protective equipment and practices.
6. maintain all factory-installed SAFETY DEVICES and make sure that these are never removed
or altered or restricted in any way.
7. the operator must have a safe and organized work area with suitable light and operating
room.
8. the whole equipment has to be correctly and constantly maintained and inspected on a
regular basis.
9. never use tools with different features from those for which the machine is designed for.
10.never use this machine to cut material bigger than the cutting capacity.
11. keep the cutting area clear of tools or other loose objects.
12. never operate the saw unless all protections are in place.
13. NEVER WEAR loose clothing, long sleeves, large gloves, jewelry, or any other items that
may be trapped into a part of the equipment. Confine long hair.
14. always disconnect the power at source when performing maintenance or making
adjustments.
15. never insert hands or arms into or near the cutting area while machine is running.
16. properly clamp the material in the vice and never hold it with your hands.
17. support suitably the bar on both sides of the machine to prevent falling.
We recommend to connect an unloading table in case the cutting length of the material is longer than the
distance between the blade and the right edge of the saw.
.
18. when cutting very short pieces, make sure they do not jam into the blade.
19. if the blade becomes jammed, turn immediately off the emergency locking button, then
move the cutting unit to the CUTTING START position. If this is not possible, open the vice
and move the piece, check that the blade or teeth are not broken, if so replace it.
20. never change the working conditions when cutting, with exception of those specifically
allowed (for example, changing speed with the Inverter).
21. do not move the saw while cutting and avoid its instability.
22. wear personal safety equipment, if required for a safe operation.

ALWAYS OPERATE THE MACHINE SAFELY,
USING COMMON SENSE AND ALERTNESS
On some parts of the machine there are some stickers which warn about the safety measures that have to be
taken by the operator who runs it. Their meaning (easy to understand) is indicated in the following chart

11.1 - OPERATOR’S SAFETY
This section illustrates the safety protections applied on the saw, according to the current
legislation in the field of safety.
11.2.1. ELECTRIC EQUIPMENT – Norm EN 60204-01
. Electric board closed with screws - general switch
. Marking of the electric components used, according to the indications on the electric scheme
. Control circuit with 24V tension – Control transformer with fuses on input and output
. Earthing of all electric parts with a dedicated GREEN/YELLOW wire, connected with a TN
system to the supply cable. A supplementary earthing point – indicated with PE – can be
located on the metallic structure of the machine.
. Minimum tension coil that prevents accidental restarting after a lack of tension.
. Protection from overloads and high temperature thanks to bimetal thermo-protectors placed
directly in the blade motor
. Emergency button for interrupting immediately all the movements of the machine. In order to
restore all the functions, rotate the button half a turn.
. Sensor of the blade tension: in case the blade breaks or the tension strength diminishes, the
machine stops immediately
. Sensor of the closing of the blade protection: if it opens during the working, the machine
stops.
. The stops caused by one of the aforementioned devices needs a complete restoring of the
working cycle
11.2.2 – PROTECTION AGAINST ACCIDENTAL CONTACTS
. Complete metallic protection of the blade and the pulleys, the blade-cleaning brush and the
back blade-driving pads
. Forward metallic moving guard, fixed to the forward blade-driving pad. It assures the
coverage of the blade in every position, except for the stretch of blade which makes the cut.
Joint to the blade-driving pad, it can be opened only after the opening of the main protection
. Positioning of the saw blade thanks to 2 buttons located on the control board, in order to limit
the width of the danger area to the stretch of blade strictly necessary for the cut.
. During the cycle an automatic approaching device stops the saw blade near the material, in
order to start the cut.
. Guard extended to both sides which retains the coolant used during the cut, preventing its
spilling on the floor
. Parts of the machine with suitably chamfered or rounded angles
11.2.5. LIGHTING OF THE WORKING AREA
An inadequate lighting can cause accidents to the operator, who consequently needs a suited
lighting in the working area. 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, APPLIED NORMS, USE
This machine is a manual band-saw with an electro-hydraulic device that allows the descent for cutting to be
completed autonomously (the blade bearing arch lowers through gravity, with a falling speed that can be
adjusted).
It is not suited to cut wood and assimilated materials (see D.M. 2006/42/CE, enclosure I,
paragraph 2.3)
All the movements that can be carried out manually are: clamping material, approach and cut (autonomous ),
tool return ( LIFTING OF THE BOW), unclamping material and movement of the bar for a new cut.
Tool start-up is controlled by a push-button switch placed on the control board.
By the emergency RED&YELLOW switch you can stop the machine at any moment, particularly during the
autonomous descent cycle.
In designing and manufacturing this machine, we have considered the requirements of the Machine Directive
(2006/42/ EEC and so on..), important document valid in all E.E.C. Countries. Furthermore we have
considered the norms as type A ( EN12100-1, EN12100-2, EN60204 ) in the case that specifications of type
C are not available. The applied safety norms are mentioned in the included compliance declaration.
The choice and the use of the parts have been made by considering the conditions of use and the long
machine life.
From the position of the work, 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.
12.1 - APPENDIX FOR E.M.C.
The structure of this machine is complying to the protection requirements of the EEC Directives 2006/42/EEC
and 2004/108/EEC in terms of Electromagnetic Compatibility (E.M.C.).
In particular it respects the technical prescriptions of the norms EN 55011 and EN 50082-2, and it is foreseen
to be used in industrial environments and not in residential ones.
