Machine presentation
This machine is equipped with CCS (Cut Control System), which is a devicethat
consents a cut for each bow fall,with controlled descent speed: after having
positioned the head in the initial cutting point, the operator fastens the material
in the vice and presses the start button on the control board to start the band up.
The band begins to rotate and the head begins to descend. Its speed is adjustable
using the head descent speed adjuster positioned on the control board.
The head determines cutting of the material. Once the cut has been made, an end
run stops the cutting cycle, after which the head is raised manually ( or with the
optional hydraulic control unit for raising of the head).
After having fed the material again a new cutting cycle can be started by pressing
the button on the control board. In the AV version (Automatic Vice) a pneumatic
cylinder applied to the vice blocks the material in the jaws: the vice opening/closing key is found on the control board.

metal shavings from the machine while cutting).
3--4
16
Use and maintenance manual S --20DS
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 different 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.
When using the pneumatic vice (MA version) check that the jaws move
right up to and effectively clamp the workpiece, as the maximum travel is
only 8 mm, and check that the clamping procedure 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 Technical Assistance Service: this can be done through a representative in the
country of use of the machine.

...Emergency devices applicable to the S ---20DS:
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 MA-
CHINES 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 S---20DS 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.
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.

Electromagnetic compatibility
As from 1 January 1996 all electrical and electronic appliances bearing the CE
marking that are sold on the European market must conform to Directive
89/336/EEC and decree law no. 476/92 concerning electromagnetic compatibility,
i.e. the compatibility of electrical/electronic devices and systems with the
electromagnetic environment in which they are located. The prescriptions regard
two specific aspects in particular:
1. “EMISSIONS: during its operation, the appliance or system must not emit spurious
electromagnetic signals of such magnitude as to contaminate the surrounding
electromagnetic environment beyond clearly prescribed limits”;
2. “IMMUNITY: the appliance or system must be able to operate correctly even when
it is placed in an electromagnetic environment that is contaminated by disturbances
of defined magnitude”.
The following text contains a list of the applied standards and the results of the
electromagnetic compatibility testing of machine model S ---20DS; Test report no.

Machine installation
Packaging and storage
Hyd---Mech use packing materials that guarantee the integrity and protection of
the machine during its transport to the customer.
The type of packing differs according to the size, weight and destination.
Therefore the customer will receive the machine in one of two following ways:
1. on a pallet with straps and heat---shrink plastic;
2. on a pallet with straps, heat---shrink plastic and a wooden crate.
In both cases, for correct balancing the machine must be handled using a
fork--lift truck, inserting the tines at the points indicated by the arrows, using
the reference marks on the crate itself.
Before carrying out lifting operations, make sure that the weight of the machine, as indicated on the crating or other packaging, is within the forklift truck
load limit.

Use and maintenance manual S --20DS
Do not handle the packed machine using slings.
When storing, machines palletized and shrink--wrapped must not be stacked
two high, and machines pallettized and crated must not be stacked three high.
To install the machine, first remove the packing, paying particular attention not to
cut any electric wires or hydraulic hoses; if necessary use pliers, a hammer and a
cutter.
