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/EEC .
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. Usefull is the reference Guide 2002
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 89/392 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.
Vibrations produced during the cut may be amplified by the material, by its dimensions and its
positioning/clamping in the vice.

8 –MOVING AND TRANSIT
For the transport of the machine only the methods indicated below are possible. However, be sure that the means of
transport and lifting are able to stand the machine's weight and its packing (about 1000 Kg):
WARNING
The personnel in charge of loading, unloading and moving the machines should use protective gloves.
WARNING
When lifting or moving the machine, or a part of it, take care of clearing the operations area of the people, considering
also an appropriate safety area around it, so as to avoid any risks of injuring people or damaging things located nearly.
Special packing –wooden crate , wooden case –may be predisposed on request, by charge.
ALL THE OPERATIONS THAT INVOLVE MOVING THE MACHINE MUST BE CONDUCTED WHILE RESPECTING
THE FOLLOWING BASIC RULES:
+ When moving the machine, an appropriate means has to be used, with a loading capacity higher than the weight to
lift, which is indicated on the machine.
+ When choosing and then using equipment such as ropes, chains or lifting belts, be careful about their geometry
during the lifting and about the consequent actual loading capacity.
+ The machine is structured so as to offer lifting points, which are appropriately indicated and will have to be used for
lifting it.
+ In case the lifting belts touch parts of the machine, nylon belts are required; ropes or chains wrapped with jute or
clean covering can also be used. A great care is necessary while slinging and moving the machine in order to hinder
damages.
+ All operations have to be conducted gradually, so as to avoid jolts and dangerous situations.
+ The person in charge of the operations has to make sure that all the national, local and company norms in reference
to injury prevention and work safety are respected.
+ One or more areas for material storage have to be identified.
Transport with machine at sight
This type of transport is usually chosen for deliveries by truck, in case of short trips. The machine is wrapped with
thermoplastic material in order to assure a suited protection of all its parts; the machine is then loaded on a truck and
should be wrapped with ropes that tie it up. To lift it, use a forklift from the front side of the machine, with forks length 1.5
m or more.
Warning: if the machine is loaded on open trucks, please cover them !
Transport with wooden crate or wooden case. ( ON REQUEST , WITH SURCHARGE )

The saw is wrapped with thermoplastic material in order to assure a suited protection of all its parts; then it is packed into
a wooden crate or cage to protect it from collisions, inclement weather and so on. To lift it, use a forklift from front side of
machine.
The machine is fixed to the packing by means of screws, so as to hinder that it can move during the transport
If the saw has to be moved around after being unpacked, make sure the sawframe is all the way down and properly
blocked, and the feeder is as close as possible to the cutting area.
9 –FITTINGS / ACCESSORIES
The information necessary for the installation are given together with the fittings. Anyway you can find here following a
short description of the product.
Loading/Unloading Roller Tables –ON REQUEST - To install them correctly, it is necessary first of all to level and fix
the machine. They are comprised of modular steel sheets, 2 meter long.
To connect it to the machine -LOADING SIDE- it is necessary to take away the first roller from the roller support of the
machine, then connect directly the roller table by using the two holes where the roller was assembled before.
The unloading table –RIGHT SIDE –can be connected directly to the unloading slide thanks to the two lateral rollers and
2 screws.
The alignment of the loading/unloading tables must begin with the one closer to the machine, taking as reference point
the worktable and the back jaw.
When cutting long bars, fix the table to the floor and make sure the coolant, which is carried by the bars, doesn’t drop on
the floor.

Vice pressure reducer - It allows to reduce the working pressure of the closing jaws compared to the general pressure of
the system. It is a modular unit and it can be assembled also later between valve-holder base and the hydraulic valve
(one for the valve of the main vice and one for the feeder vice); it doesn’t require any cable connections. By opening the
left side front door you can adjust the pressure.
Vertical rollers –they allow to clamp more bars together on the same row. They prevent the bars from lifting and from not
being properly clamped when the vice closes.
Hydraulic vertical vices for cutting bundles - RI0433 e RI0434 –connected to the standard vices, they allow to feed
and cut a bundle of bars; minimum length 110mm, max length 300mm, max height 120mm
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 depending from air supply.
It is comprised of a nozzle - 1/RI0463 - with 3 micro-holes, a tank with devices to adjust the quantity of oil and the air
pressure. The switch of the electric system - 3/RI0462 - working with low tension 24V AC allows to turn it off at any
moment and use the normal coolant system. Remove the nozzle 1/RI0463 to obtain the maximal cutting capacity.

Voltage transformer - place it between the electric supply of the premises and the electric supply of the machine. It
allows to work with a different voltage than the standard one (that is 400V / 50 Hz). Available voltages: 230V, 460V, 500V,
575V.
7 - BLADE CHOICE
In this paragraph we recommend the type of blade according to the material to cut. To get the best performance from this
machine it is necessary to understand how to use the tools and what you do not have to do with them. The blade for this
bandsaw must have the following size (mm) :
maximum length = 2770 minimum length = 2750 height = 27 thickness =0,9
The type of blade is also important, usually it’s a bi-metal blade with different HARDNESS, named M42 or SVGLB ( for
general purpose, tubes, profiles and solids, available in all pitch type), M51 or SHL (preferred for big solids of
hardening steel, INOX material too, available with 3/4 tooth pitch).
The durability of the teeth increases, and also the fragility, when going from the material M42 to M51.
To making a correct cut it’s essential to choose the pitch ( t ) or the number of the teeth per inch (z). Usually the
blade must have a pitch as follows :
- high pitch (small teeth), to cut thin materials, tubular and profiles.
- low pitch (big teeth), to cut solids or particular sections that require at times a big blade effort (for example, the central
part of a U profile), or softer materials as aluminium, copper, soft bronze.
By choosing the right one you can avoid a lot of working errors, get a good cut and the necessary room for the chips. If
you cut more bars at the same time, you must consider them as a single bar and consider the total size. The
following table provide the information for a correct choice, it can also be updated or modified by the user according
to his personal experiences.
Even if blades with constant pitch are available, most bandsaws allow to use blades with variable pitch - groups of teeth
with different pitch between them - which reduce vibrations and noise, improving the quality of the cut and the
performance.

11. INSTRUCTIONS FOR USE AND WARNINGS
This bandsaw can carry out cutting cycles, at the end of which the material that has been cut has to be removed and if
necessary the cutting conditions have to be changed = SEMIAUTOMATIC CYCLES
It can also perform autonomous cutting cycles, including the feeding of the bar until it has been completely cut =
AUTOMATIC CYCLES
Thus the machine can be driven by the operator or carry out a cutting cycle automatically, which ends when the machine
stops. The starting procedure has to be repeated to begin a new one.
11.1 - This machine is designed and manufactured so as to be safely used by the operator, provided that it is
properly run. No protections will ever suffice if the operator does not work with caution, does not make sure that the
machine is in top working conditions and does not follow the instructions below.
Don’t forget that this bandsaw is designed to CUT METALS with a proper tool, and that you are responsible for a SAFE
and CORRECT use. You must :
1. check that the machine is properly installed and electric supply is suited.
2. be sure to learn all main features of the saw before running it.
3. do not expose yourself or any other people to any risk.
4. wear personal protective equipment
5. do not remove or modify the SAFETY DEVICES installed by the manufacturer, make sure that they are always in a
good condition, too.
6. follow a regular maintenance schedule and check regularly the efficiency of the saw.
7. never use tools with unsuited characteristics
8. do not try to cut material with a size bigger than the cutting capacity of the machine
9. Keep the cutting area clear of tools or other loose objects.
10. do not run the saw unless all guards and protections are in place
11. NEVER WEAR loose clothing, long sleeves, large gloves, jewellery, or any other items that may get entrapped into the
machine
12. Always disconnect the power supply when performing maintenance or making adjustments.
13. do not get close to the cutting area with your hands or any other part of your body when the saw is running
14. Clamp properly the material in the vice and never hold it with your hands
15. Support appropriately the bar from both sides to prevent it from falling
We recommend to install a roller table on the unloading side in case the cutting length of the bar is
bigger than the distance between the blade and the right side of the basement
16. When cutting very short pieces, make sure they do not jam into the blade.
17. If the blade remains entangled with the material, stop the machine, open the vice and remove the material, then check
the condition of the blade and the teeth: if they are damaged or broken, change the blade
18. Apply a constant pressure during the cut
19. Do not move the saw during the cut or cause instability
20. Wear personal safety equipment when running the machine
ALWAYS RUN THE SAW 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 explained in the following chart
11.2 - OPERATOR’S SAFETY

ISTRUZIONI PER L’USO-
BS 300/60 AFI-NC ED.2010 rev.00
18/59
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 the 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 to stop the machine immediately. In order to restore all functions, turn it right 1/4 of a round
. Sensor of the blade tension: in case the blade breaks or the tension is not enough, the machine stops.
. Sensor of the closing of the blade protection: if it opens during the working, the machine stops.
. Sensor of the closing of the feeder guard: if it opens while the saw is running, it stops.
. Sensors for vices: they check that the vices aren’t in the wrong position (i.e. too far or too close to the material)
. 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, the pulleys, the blade-cleaning brush and the back blade-driving pads
. Forward metallic mobile 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. It can be opened only after opening the main protection
. Positioning of the blade close to the material thanks to a pair of buttons located on the control board, in order to contain
the width of the danger area to the stretch of blade strictly necessary for the cut.
. Clamping vices with a maximum stroke of 7 mm, according to the norms on automatic closing
. Guard extended to both sides of the floor stand which retains the coolant used during the cut, preventing it from spilling
on the floor
. Parts of the machine with suitably chamfered or rounded angles.
11.2.5. LIGHTING OF THE WORKING AREA
An inappropriate 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 recommend to supply a
lighting equal to 750 LUX

12 - MACHINE DESCRIPTION
This is a semiautomatic/automatic electronic, hydraulic bandsaw equipped with position sensor that allows a fast drop by
the sawframe. Suitable for cutting metal profiles and solids from 0° to 60° left.
It is not suitable to cut wood and similar materials (see D.M. 89/392, enclosure I, paragraph 2.3).
The automatic cycle is comprised of: clamping the material, feeding and cutting, sawframe return and unclamping of the
material. The operator has to adjust the cutting parameters, the sawframe rotation for miter cutting and to load a new bar
at the end of each cutting cycle. The feeder strokes, the cutting lengths and the number of cuts are programmed by
means of the keyboard.
The Safety Norms and the Directives applied are mentioned in the enclosed Declaration of Conformity.
From the working position in front of the saw - WORKING AREA - the operator can activate all drivers, check the correct
working of the saw and avoid dangerous areas.
In the following paragraphs you will find all information for using
the machine in the best way and for a very long time.
- 13 - MACHINE SET-UP
Verify that machine does not have damages or faults and check the standard equipment which includes tools, fittings to
perform some adjustments, user’s book.
In case the machine is supplied with additional equipment, make sure it is suited to the machine. Point out promptly
possible damages or faults to the reseller or to the service staff before running the saw.
Remove the locking bracket between the sawframe and the basement and put it in the left side of the floor stand -
11/RI0439 and place the plastic screw in the hole of band guide support -/RI0461-
- Remove the protective elements placed on the machine in order to safeguard it when shipping it and handling it, by
using proper objects or paper. Check also that there is no rust on the metallic parts.
In case compressed air jet is used, always wear proper eye protection.

Take out the chip collector tank located in the back –5/RI0439 - by unhooking it from the guides, then remove possible
objects inside which can hinder the coolant flow.
The parts in motion (band guides, trolleys, hinges, bearings, and so on) are already lubricated, the gear box contains the
precise quantity of oil needed to work. The hydraulic system is ready to start.
- 13.1 - COOLANT
Prepare the coolant by mixing cutting oil and water (the tank capacity is about 60 liters) in proportion 1/10, 1/15 or
according to the instructions provided by the supplier. Pour in the coolant in the tank –accessible in the back side of the
floor stand - or directly on the work table. In this case make sure that the chip tank is correctly placed.
13.2 –PNEUMATIC CONNECTION (OPTION, IF THE MINIMAL LUBRICATION SYSTEM IS APPLIED)
The bandsaw is provided with reducer + air lubricator, but it’s recommended to connect it to a system to unload
condensate, with cables correctly installed and a pressure of at least 7/8 BAR. The air consume is about 1 NI for each
cycle.
- 13.3 - ELECTRICAL CONNECTION
Verify that voltage and power frequency are compatible with the figures shown in the technical data plate (placed on the
right side of the floor stand); a difference over 10% causes some working troubles.
This operation must be performed by authorized operators (i.e. by an electrician ). 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, N=neutral wire;
Anyhow check what follows (with the blade protection closed):
a) if the Emergency button is pressed, turn it 1/4 of a round in the direction indicated by an arrow
b) turn on the main switch, located on right side of the floor stand: a few lights turn on, on the display some numbers
related to the programming appear and the motor of the hydraulic unit turns on.
c) verify that the manometer of the hydraulic unit indicates a pressure of at least 18/20 Bar, and push the buttons -
3/RI0408 - or - 13/RI0408 - to move the sawframe up and down.
If this doesn’t happen within 5/10 seconds, turn off the saw by means of the main switch, disconnect the feeding
plug and exchange the connection of two wires, with exception of the green/yellow earthing wire and NEUTRAL
wire. Then start again from point a)
e) verify that the coolant flows correctly from the tank to the cutting area (when the taps are opened and the pump is
active).
f) stop the machine by means of the main switch
