GENERAL
TECHNICA has been designed in compliance to the European Community normative (CE) .
From the design stage, risks for the operator have been eliminated in all areas: transport, regulation, cutting and
maintenance.
Risks have been eliminated by means of protective devices.
The use of protective goggles is compulsory during cutting operations, as indicated on the machine itself and in this
manual.
The materials used to manufacture this machine and all its components are not hazardous
.
USE
The TECHNICA must be installed and used in the way laid down by the manufacturer .
If the key-cutting machine is used differently or for purposes different from those described in this manual, the
customer will forego any rights he may have over
Silca . 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 of 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
TECHNICA and benefit from its potential.
Instructions manual
The instructions manual provided with the machine is essential to its proper use and to carry out the necessary
maintenance.
We therefore recommend protecting the manual from damage in a safe sheltered place, easily to hand for quick
consultation.
Further risks
• when the machine is in operation only the operator should be close
to it as the moving tools are partially exposed and metal swarf is
generated by machining .
•
before activating the master switch (A) (fig. 5, page 5), the operator
must make sure that the cutter motor starting switch is in position
"0" (fig. 38, page 23).
•
when the machine is in operation, area "A" (fig. 2) can be hazardous
for the operator and any third parties in the proximity of the key-
cutting machine if the warnings and precautions given in this
manual are not observed .
Fig. 2
Protection and safety precautions for the operator
The TECHNICA key-cutting machine is entirely built in compliance to the Machine Directives. The operations for
which it has been designed are easily carried out with no risk to the operator.
The adoption of general safety precautions (wearing protective goggles) and observation of the instructions
provided by the manufacturer in this manual eliminate all human error, unless deliberate.
TECHNICA is designed with features which make it completely safe .
• Power Supply
The key-cutting machine must be supplied with electricity. The plug must be earthed .
• Electric power
The machine is started up by means of the master switch .
• Start-up
The speed commutator activates the machine and allows selection of the required speed.
• Maintenance
The operations to regulate, service, repair and clean the machine are structured in the simplest and safest way
possible. Parts that the operator can dismount cannot be incorrectly replaced therefore avoiding any risks
.

1 MACHINE DESCRIPTION
Fig. 4
1.1 Main Characteristics
•KEY-CUTTING UNIT WITH CARRIAGE
The key-cutting unit contains the working parts of the TECHNICA key-cutting machine, which carry out reading
and cutting of the original key and the necessary finishing off. The working parts are
:
Cutter:
The cutter is the part of the key-cutting machine used to cut keys. It is in super rapid steel (HSS) and is protected
by a special shield to guarantee safety for the operator.
Tracer point unit:
The tracer point is dedicated to reading the cuts on the keys. It is easily regulated (depth and axial gauging).
Carriage:
The carriage comprises a clamp unit for cutting bit-double bit and pump keys.
The carriage movement is horizontal on 2 axes (X-Y) and controlled by means of the lever (L) (fig. 5, page 5).
The knob (R) is used for rounding off bit and double bit keys.
Clamps for bit-double bit and pump keys:
The clamps comprise two self-centering jaws that ensure perfect grip on the stem of bit-double bit and pump keys
(with round or square stems).
•MASTER SWITCH
The master switch is located on the bottom left-hand side of the lamp.
•MOTOR ON SWITCH /SPEED COMMUTATOR
On the top left-hand side there is a switch for starting the motor at the required speed.
•ILLUMINATION
The lamp is fixed and it illuminates the work zone to be used perfectly.
