1.4 - Machine description
The pasta machine you have purchased is a straightforward, compact machine
guaranteeing powerful operation and high performance.
- Since it must be used to produce food products, all components that can come
into contact with such products have been carefully chosen to guarantee the
utmost hygiene.
- The bowl is made of 6060 anodised aluminium alloy and grade AISI 304
stainless steel.
- The accessory tool (blade) is made of grade AISI 304 stainless steel.
- The mouth and the screw are made of AISI 304 stainless steel and ø75 dies of
bronze.
- Two operating modes: kneading and extruding mode.
- Maximum dough capacity of 4.2 kg (3 kg of flour + 1.2 kg of eggs).
- Possibility of adding the pasta cutter accessory.
- Single-phase ventilated motors offering the following advantages:
- extremely constant performance and motor duration;
- longer actual work time thanks to fewer interruptions.
The models appearing in this manual are manufactured in conformity to Directive
UL 763-CSA 22.2 and subsequent amendments.
If any accident occurs, the manufacturer shall not be held liable if the machine was
modified, tampered with, with its safety guards removed or used for purposes other
than the intended use specified by the manufacturer.
1.5 - Intended use
The machine is designed to produce fresh-made pasta.
It must be used in a professional setting by qualified operators who have read and
understood this manual. Use the machine exclusively when it is securely placed on
a solid worktable.
After every work cycle, we recommend leaving the machine to rest for a few
minutes before using it again.
1.6 - Improper use
The machine must only be used for its intended purposes; in particular:

6
- Do not use the machine for food products other than pasta and similar.
- Do not use the machine unless it has been properly installed with all its guards
in good working order and correctly fitted, to prevent the risk of serious injury.
- Do not access any of the electrical components without having first
disconnected the machine from the mains power supply: risk of electric shock.
- Follow the proportions of flour and liquid indicated in the use and maintenance
manual. An incorrect flour/egg ratio may also damage the machine
permanently.
- Do not wear clothing that fails to comply with the accident-prevention
regulations. Consult your employer for information on the applicable safety
regulations and personal protective equipment to be worn.
- Do not start the machine if it has a fault.
- Before using the machine, make sure that any potentially hazardous conditions
have been adequately eliminated. If you notice anything unusual in its
operation, shut down the machine and inform the maintenance supervisors.
- Do not allow unauthorised personnel to intervene on the machine.
In case of injury caused by electric shock, the first thing to do is to detach the
injured person from live conductors (as the person will probably be
unconscious).
This operation is highly dangerous.
The injured person in this situation is a conductor: touching him/her would give
you an electric shock.
It would be better to disconnect the mains power supply, or if this is not
possible, move the injured person away using non-conductive materials (a rod
made of wood or PVC, fabric, leather, etc.). First-aid medical assistance should
be requested promptly and the injured person should be taken to hospital.
