Its high cutting capacity, combined with the possibility of making inclined cuts from 60˚ left to 60˚ right, make this model the ideal solution for satisfying the wide strange of cutting needs of machine shops, turneries, structural steel shops and engineering workshops. We congratulate our clients on having chosen this product, which will give effective and faithful service for many years, especially if the instructions contained in this use and maintenance manual are carefully followed.
This band saw has been exclusively designed to cut metals.
Machine presentation
Functioning is SEMI ---AUTOMATIC. In Semi ---automatic mode, after setting the head cutting stroke on the control panel and the head downstroke speed, the operator positions the vice 2÷3 mm from the workpiece and presses the start button (or optional foot pedal if fitted) on the control panel to start up the band saw. The vice then clamps the material, the head lowers, cuts the piece and returns to its start position and the vice opens again.

Use of the machine
The S20DSP band saw cutting machine is intended exclusively for cutting metallic materials, ferrous or non ---ferrous, in section or solid. Other types of material and machining are not compatible with the s pecific characteristics of the saw. The employer is responsible for instructing the personnel who, in turn, are obliged to inform the operator of any accident risks, safety devices, noise emission and accident prevention regulations provided for by international standards and national laws regarding the use of the machine. The operator must be perfectly aware of the position and function of all the machine’s controls.The instructions, warnings and accident prevention standards in this manual must be respected without question by all those concerned.The following definitions are those provided for by EEC MACHINES DIRECTIVE 98/37/CE :
H “Danger zone”: any zone in and/or around a machine in which the presence of a
person constitutes a risk for the safety and health of that person.
H “Person exposed”: any person finding himself either completely or partly in a
danger zone.
H “Operator”: the person or persons given the responsibility of installing, operating,
adjusting, maintaining, cleaning, repairing or transporting the machine.
The manufacturer declines any responsibility whatsoever, either civil or crimi­nal, should there be unauthorised interference or replacement of one or more parts or assemblies on the machine, or if accessories, tools and consumable materials are used that are different from those recommended by the manu­facturer itself or if the machine is employed in a plant system and its proper function is thereby altered.

Any maintenance work on the hydraulic or pneumatic systems must be carried out only after the pressure in the system has been released.
The o perator must not perform any risky operations or operations not required for the machining operati on under way (e.g. remove swarf or metal shavings from the machine while cutting).
Remove equipment, tools or any other objects from the cutting zone; always keep the working area as clean as possible.
Before starting any cutting operations, ensure that the workpiece is securely held in the vice and the machine has been set correctly. A number of examples of how to clamp different profiles correctly in our machines are shown below.
Do not use the machine to cut pieces that exceed the capacity of the machine as listed in the machine specifications.
Never move the machine while it is cutting.
Do not use blades of dif ferent sizes to those recommended in the machine specifications.
When cutting very short pieces, make sure that they are not dragged behind the support shoulder, where they could jam in the blade.

Safety and accident prevention
When the hydraulic vice is used automatically, check it actually locks the piece, as its stroke is 8 mm only, and that the tightening pressure is cor­rect.
When working on the band saw, wear gloves only when handling materials and for tool changing or adjustment operations. Only perform one operation at a time and do not hold more than one item or operate more than one device simultaneously. Keep hands as clean as possible.
Warning: if the blade jams in the cut, press the emergency stop push--­button immediately. If this does not free the blade, slowly loosen the vice, remove the piece and check the blade or blade teeth for breakage. Replace the blade if necessary.
Before carrying out any repair work on the machine, consult the Hyd--- Mech Technical Assistance Service: this can be done through a representative in the country of use of the machine.

...Emergency devices applicable to the S20DSP:
1. Emergency stop: a non---return mushroom---head pushbutton, colour red on yellow background, is located on the control panel of the machine. To release the pushbutton, the actuator must be rotated 45˚. After the emergency situ­ation has been resolved, the machine must be reset.
2. Automatic thermal ---magnetic cutout switch with thermal--- magnetic relay: The machine’s automatic switch, positioned on the left---hand side of the base, has two protective systems against the lack of voltage. In fact, if there is a lack of voltage, it disconnects all electrical devices, blocking the machine immediately and impedes the automatic restore of the voltage. The other function is that of re---arming the circuit breaker relay, positioned to protect from the overloads of current.
3. Pressure transducer for monitoring the blade tension: the machine stops im­mediately if the blade breaks or the tensioner cylinder pressure drops.
4. Protective guard for blade: a coded key microswitch is operated if the blade cover is accidentally or intentionally opened during the machine operating cycle, immediately shutting down all functions.

Noise level of the machine
Noise can cause hearing damage and represents one the problems faced by many countries who adopt their own standards. In accordance with the EEC MACHINES DIRECTIVE 98/37/CE , we are listing the standards that specify noise levels for machine tools. This chapter also reports the noise levels produced by the S20DSP during its various operating phases and the methods used for measuring these levels. The Italian standard governing this aspect is D.M.n.277/91 drawn from EEC Directives 80/1107, 82/605, 83/477, 86/188, 88/642, UNI EN ISO 4871 (1998).
Noise level measurement
Noise levels are measured using an instrument known as an Integrator noise--­meter which registers the equivalent continuous acoustic pressure level at the work station.The damage caused by noise depends on three parameters: level, frequency and duration. The equivalent level concept Leq combines the three parameters and supplies just one indication. The Leq is based on the principle of equal energy, and represents the continuous stationary level containing the same amount of energy, expressed in dBA, as that actually fluctuating over the same period of time.This calculation is made automatically by the integrator noise --­meter. The measurements are taken every 60 seconds, in order to obtain a stabilised value. The reading stays on the display for a sufficient time to enable a reading to be taken by the operator.Measurements are taken by holding the instrument at approximately 1 metre from the machine at a height of 1.60 metres above the platform at the operator’s work station. Two measurements are taken: the first while the machine operates without cutting anything, the second while cutting in manual mode.

Connection to the power supply
Before connecting the machine to the power supply, check that the socket is not connected in series with other machines. This requirement is fundamental for the good operation of the machine.
To connect the machine to the power supply, proceed as follows:
" connect the power supply cable of the machine to a plug which matches the
socket to be used. (EN 60204 ---1; par. 5.3.2)

THERMAL- MAGNETIC CIRCUIT- BREAKER WITH UNDERVOLTAGE COIL AND DOOR LOCKING DEVICE
On the left side of the control board, the machine is equipped with a main switch that, when set ON (1), powers the machine. When set to ON (1), this switch powers up the machine. The main switch is fitted with three power failure protection systems. In fact, in the event of a power failure, this switch disconnects all the electrical devices, causing the machine to immediately shut down, and prevents it from automatically starting up again when power is restored. This device also resets the thermal relay fitted to protect against current overloads.
Basic instructions for carrying out a cutting operation cycle
Manoeuvring the cutting head
The cutting head may be operated by the head “up” and “down” buttons of the Head Positioning System (previously illustrated in the key for the control console keyboard), which are enabled in SEMI ---AUTOMATIC mode.
Head “down” key Head “up” key
During any processing cycle it is possible to control the machine operating parameters TL (blade tensioning) and PT (head position), pressing the key below it is also possible to display the values VL (blade speed), T (cutting time), PZ (cut piece counting) and I (motor current absorption).

Preliminary check list for cutting operation
To guarantee complete safety during cutting cycles, the operator should work through a check list of the entire apparatus, checking:
" blade tension; " that the blade guide head bracket is locked in the correct position; " that the cutting angle is correct and the cutting head is locked; " that the work piece is properly clamped in place; " that the blade teeth are correct for the job to be begun; " that the speed selected is right for the kind of piece to be cut; " that all protections are in place and correctly locked; " the level of lubricant/coolant and that the electropump is activated; " That the blade descent speed is correct.
Semi--automatic operating cycle
Semi---automatic cutting sequence:
" power up the machine by turning the main switch; " position the workpiece in the vice.
During this programming phase of the cycle, do not position the workpiece per­pendicular to the blade so that the head may be moved up and down without colliding with the workpiece.
" Select semi---automatic mode by pressing the corresponding button on the
control console.

Adjustments
This chapter describes the operations required to adjust the electronic, mechan­ical and the hydraulic systems. By following these instructions, you can “custom­ise” your machine to suit the type of cut required, thereby optimising cutting times.
Displaying and editing the set--up parameters
The machine set---up parameters may be programmed directly from the control console.
" Power up the machine at the main switch located on the left hand side.
" Press simultaneously and in sequence the keys MACHINE PARAMETERS
and MACHINE START;

" Once inside the SET---UP menu, use the following three keys to navigate
through the different menu screens:
FCTA Head Downstro-
ke Limit
FCTI Head Upstroke
Limit
“Clear” key
" The FCTA key (Y) allows you to change parameter settings in increments of
one unit.

Cutting head stroke
The cutting head crosses the space between the forward and backward position definable in the SET---UP with the CUTTING HEAD POSITION parameter. A value between 000 and 300 must be set. Check that the bow, really and not virtually, crosses the amplitude of the cut between the structural limits of cutting head backward end run and cutting head forward end run. The scope of adjust­ment is to set the value of the real cutting head position both at FCTI (backward limit 275÷300) and at F CTA (forward limit 008÷012). Two adjustments are performed to obtain this result: one on the cutting head cylinder and the other on the IUD/IUV layout of the M30 controller. Operation sequences:
" Power the machine rotating the main switch on the left side of the console; " Press simultaneously and in sequence the keys MACHINE PARAMETERS
and MACHINE START;
" Press the RESET.

Adjusting the display brightness
If external factors like changing ambient lighting conditions in the machine installation site, affect visibility, adjust the brightness of the control and program­ming console display. This is very important since the operator must be able to clearly read the display messages at all times.
" To adjust the brightness, first remove the screws fixing the front console
panel. The photo below illustrates the M30 controller card on which the
brightness potentiometer is marked by an arrow.
" Using a screwdriver, rotate the potentiometer until the required display
brightness is obtained.

Adjustments
Machine working pressures
This section describes the procedures to change the vice and head operating pressures. Both adjustments strongly depend on the material type being pro­cessed. Thevicelockingpressurecanbesetifthematerialcouldbestrainedorcouldbe quite unstable while cutting. The head lowering speed can be set by a flow adjuster on the control console.
Hydraulic pressure
Both vice and head pressures can be adjusted by the power packs.
Both the pneumatic and hydraulic vices have a maximum travel of 8 mm. This means that after positioning the workpiece on the work table and before start­ing the cycle, the moving jaw must be positioned to within 2÷3mmofthe workpiece as previously described in Chapter 5.
The operating pressures (shearing vice and cutting head) can be adjusted by the max. pressure adjusting valve.
" Open the door of the machine base, remove the fastening screws and pull out
the power pack from inside the base.
" Slacken the hex nut on the relief valve, and using an Allen key, increase
(clockwise) or reduce (counter---clockwise) the pressure reading on the pres­sure gauge.
" This done, tighten the lock nut and return the hydraulic power pack back in-
side the base.

Blade tension er slide p lay adjustment
To reduce the play which may develop over time between the blade tensioner slide and slide gibs, adjust the grub screws between the gibs and slide as follows:
" open the cutting head cover; " un ---tension the band with the relevant hand---wheel: " remove the blade from the flywheels; " remove the plug connecting the slideway to the cylinder rod; " move the slide back and forwards to locate any friction or excessive play; " slacken the nuts, using a tubular nut driver to hold the grub screws firm;
" finally, tighten the grub screws to take up any play or otherwise, slacken them
to reduce any friction.
