GENERAL INTRODUCTION
The TWISTER II key-cutting machine has been designed according to CE specifications. From the design stage
risks for the operator have been eliminated in all areas: transport, key- cutting, regulation and maintenance.
Other risks have been eliminated by the use of protective devices for the operator.
The protective devices used 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 cutting
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 TWISTER II must be installed and used as specified by the manufacturer.
The TWISTER II key-cutting machine must be used only by skilled personnel (professional use).
The key-cutting machine is designed for use on business or industrial premises (e.g. hardware shops, key cutting
centers, etc...).
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 the Company. 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 OBLIGATORY to read the manual carefully before using the machine.
Further Risks
There are no further risks arising from the use of the machine.
Protection and safety precautions for the operator
The TWISTER II key-cutting machine is built entirely to CE standards. The operations for which it has been
designed are easily carried out at 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. The TWISTER II key-
cutting machine is designed with features which make it completely safe in all of its parts and operation.
• Power supply
The key-cutting machine is powered by electricity supplied through a separate grounded plug.
• Start-up
The machine is turned on by means of the master switch located on the left-hand side. The switch has a safety
function that prevents untimely start-up when voltage returns after a power outage.
• Operation
The machine is started up by means of a motor switch.
• Illumination
The work area is illuminated by a lamp which operates when the machine is switched on with the master switch.
• 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.

damage.
1.3 UNPACKING
To remove the machine from the packing box:
1) Cut the straps with scissors and remove.
2) Open the box without damaging it so that it may be used again (e.g. shipping to the manufacturer for repairs or
servicing).
3) Check the contents of the box, which should comprise:
1 TWISTER II key-cutting machine packed in a protective shell.
1 set of documents, including: operating manual, spare parts list and guarantee.
1 accessory container.
1 separate grounded plug wire.
4) Remove the key-cutting machine from the protective shell.
1.4 HANDLING THE MACHINE

This system guides and facilitates self-centering of the cuts on dimple keys.
• PROTECTIVE SHIELD
A special transparent plastic shield minimizes exposure to the cutter and chips.
• LAMP
Placed directly on the machine, it illuminates the work area.
• TRACER POINT ADJUSTING RING NUT
Ensures perfect depth alignment of the tools and makes it possible to adjust for defects on worn keys.
• LEVERS AND KNOBS

Materials and finish have been chosen according to the use of each part, especially:
• lever (I) for vertical carriage (Z axis)
• lever (C) X-Y axes
Note: the letters in brackets refer to Fig. 6, page 7.
The lever which guides movement along the X-Y axes is ergonomic and allows for precise, sensitive movements.
