GENERAL INTRODUCTIONS
The DUO key-cutting machine has been designed according to the specifications of the Machine Direc-
tives. From the design stage risks for the operator have been eliminated in all areas: transport, key-cut-
ting, regulation and maintenance.
Other risks have been eliminated by the use of protective devices for the operator.
The protective devices us ed are designed not to provoke further risks and , above all, they cannot be
ignored unless deliberately cut out. They do not hinder visibility of the work area.
A special adhesive label is attached to the machine warning the operator to use goggles during the cut-
ting operations, and this is strongly recommended in this manual.
The material used in the manufacture of this machine and the components employed during use of the
machine are not dangerous and their use complies with standards.
Use
The DUO must be installed and used in the way laid down by the manufacturer.
If th e key-cuttin g ma chine is used differently or for purposes differ ent from those describe d in this
manual, the customer will forego any rights he may have over SILCA S.p.A. Furthermore, unforeseen
danger to the operator or any third parties may arise from incorrect use of the machine.
Negligence in the use of the machine or failure on the part of the operator to observe the instructions
given in this manual are not covered by the guarantee and the manufacturer declines all responsibility
in such cases.
It is therefore indispensable to read the operating manual carefully in order to make the best use
of the DUO and benefit from its potential.
Instructions manual
The instructions manual provided with the machine is essential to i ts proper use and to carry out th e
necessary maintenance.
We therefore recommend protecting the manual from damage in a safe sheltered place, easily to hand
for quick consultation.
Further Risks
There are no further risks arising from the use of the machine.
Protection and safety precautions for the operator
The DUO key-cutting machine is built entirely to standards. The operations for wh ich it has been de-
signed are easily carried out at no risk to the operator.
The adoption of general safety precautions (wearing protective goggles) and observation of the instruc-
tions provided by the manufacturer in this manual eliminate all human error, unless deliberate.
The DUO key-cutting machine is designed with features which make it completely safe in all its parts.
• Power supply
The key-cutting machine is powered by electricity supplied through a separable earthed plug.
•Start-up
The machine is started up:
- activating the safety main switch on the left-hand side of the machine;
- activating the motor on switch the left-hand side.
• Maintenance
The operations to regulate, service, repair and clean the machine have been devised in the simplest and
safest way possible. There is no danger of removable parts being re-placed wrongly or unsafely.
• Machine Identification
The DUO key-cutting machine is provided with an identification label which shows the serial number (fig.
3).

1 TRANSPORT
The DUO key-cutting machine is easily transported and is not dangerous to handle. The packed ma-
chine can be carried by one person.
1.1 Packing
The DUO is packed in a strong cardboard box, the dimensions of which are shown in fig. 4, sufficiently
robust to be used for storing the machine for long periods.
Inside the box the machine is enclosed in two expanded polymer shells. The shells and cardboard box
ensure safe transportation and protect the machine and all its parts.
Fig. 4
1.2 Transport
To avoid damaging the DUO it must always be transported in its packing case. This will prevent sudden
movements or rough handling from damaging the machine, persons or things.
1.3 Unpacking
To remove the machine from the packing box:
1) cut the straps with scissors and remove,
2) prise off the staples,
3) open the box without damaging it as it may be used again (e.g. removals, dispatch to the manufac-
turers for repairs or servicing),
4) check the contents of the box, which should comprise:
- 1 DUO key-cutting machine packed in a protective shell;
- 1 set of documents, including: operating manual, spare parts list and guarantee;
- 1 connecting wire;
- 1 tool kit
5) remove the key-cutting machine from the protective shell.
1.4 Handling the machine
When the DUO has been unpacked, place it directly on its workbench.
This operation can be carried out by one person, firmly holding the base, and no other part, to lift and
carry the machine.

4 MACHINE DESCRIPTION
DUO is a professional key-cutting machine, designed to duplicate:
• flat keys for cylinders and vehicles and cruciform keys: with left-hand carriage.
• bit, double bit, pump and mail box keys*: with right-hand carriage.
Fig. 7
The main parts of the machine are described below:
Main switch
The ke y-cutting machine is co nnected to a pow er supply so cket provided wit h a differentia l switch.
Pressing the switch (T) powers the machine and illuminates the lamps (R) to indicate that current is on.
ATTENTION: Switch (T) is electromagnetic, in the event of a power failure it goes out automatically. When
electricity is restored it must be reset manually to power the machine again.
Motor on switch
On the left-hand side of the DUO key-cutting machine there is also a switch for starting up the motor (U).
ATTENTION: the illuminated switch remains on to indicate that the key-cutting machine has been started
(cutter in motion).
Motor and transmission unit
Motor transmission takes place by belt.
On the right-hand side of the motor there is the transmission shaft which moves the brush (P).
On the left-hand side of the motor there is the shaft which moves the cutter spindle.
These components are protected by a top cover (Q).
Clamp carriages
The carriages comprise two clamps. They move horizontally and frontally controlled by handles (C and
H).
The DUO machine carriages can be locked into a fixed position and in this way achieve translation by
means of the flywheel located on the right-hand side of the machine (chap.8.1.3, page 21) (Attention:
not available on Duo Brazil version).
The carriages are so designed as to avoid accumulation of dust or cutting swarf.
The machine is designed with a ramp along which chippings can fall into the special chippings tray (S)
placed under the carriage and easily removable for emptying and cleaning.
Cutting unit
The cutting unit contains the actual wo rking parts of the DUO key-cutting machine , which operate to-
gether to cut and finish keys "read" from the originals.
The working parts are described below:
•Cutting Tools
The cutting tools (F) and (M) are the parts of the DUO used for cutting key blanks. The cutting tools are
in HSS super rapid steel and are protected by a special cover (W) to ensure safe operation. The shield
(W) is mobile and can be placed over the cutter that is not in use.
• Tracer points
The tracer points are dedicated to reading cuts on the key to be duplicated and are:
- tracer point (G) on the left-hand side of the machine, for flat keys for cylinders and vehicles and cru-
ciform keys;
- tracer point (N) on the right-hand side of the machine, for bit, double bit, pump and mail box keys*.
The depth of the tracer points is easily regulated by means of the relative graduated nut.
* Mail box keys only on DUO and DUO BRAZIL versions
