3 Testing, transport, delivery, and installation
3.1 - Testing
The machine in your possession has been tested in our facotry to ensure it runs
properly and is correctly regulated.
3.2 - Machine delivery and handling
All the forwarded material has
been accurately checked prior to
delivery to the shipping agent.
Unless otherwise stipulated by
the client or hindered by
particularly burdensome
transport, the machine is
wrapped with nylon and
carboard.
The packaging dimensions are
shown in fig. 3.2.1 When the machine is received
check that the packaging is intact. Should the packaging be damaged sign the
transport documents, noting that: " I accept, but ..." and the reason.

been genuinely damaged, declare such damage to the shipping agent within three
days of the date indicated on the transport documents.
3.3 - Installation
ATTENTION!
The area where you intend to install the machine must be flat and solid.
Furthermore, the machine must be positioned with ample space around it.
This enables greater maneuverability during working phases and guarantees
access for periodic maintenance. Ensure sufficient lighting around the machine to
guarantee correct visibility for the machine operator.
3.3.1 - Package disposal
The components of the packaging such as cardboard, nylon and wood can be
freely disposed of as they are compatible with solid urban waste.
Nylon is a pollutant if it is burned because it produces toxic fumes. Do not burn and
do not throw away but dispose of it according to the laws in force.
If the machine is delivered in countries in which there are particular laws, dispose
of the packaging according to the presciptions of these laws in force.
3.3.2 - Moving the machine
ATTENTION!
Lift the machine with a forklift of suitable capacity.
Check the stability and positioning of the weight on the forks,
especially along uneven, slippery or inclined paths. When mo-
ving the machine keep the load as low as possible to guaran-
tee greater stability and visibility.
Stabilize the grip by widening the forks of the forklift.

1.6 - Forbidden uses
The machine must only be used for the purposes expressly intended by the manu-
facturer. In particular:
- Do not use the machine to grate food products other than cheese, bread and
the like.
- Do not use the machine if it has not been correctly installed with all the protec-
tions intact and correctly assembled to avoid the risk of severe injury.
- Do not access electrical components without having previously disconnected
the machine: risk of electrocution.
- Do not work products that are bigger than what can be totally contained in the
feeding inlet.
- Do not wear clothes that do not comply with safety regulations. Consult your
employer for safety regulations and the safety devices required.
- Do not use the machine if it is not working correctly.
Before starting the machine make sure that any dangerous condition has been
appropriately eliminated. If a fault occurs, stop the machine and notify persons
in charge of maintenance.
- Do not allow unauthorized personnel to carry out work on the machine.
In the event of emergency treatment due to an accident caused by electrical
shock, first remove the victim from the conductor (as he will be unconscious).
This operation is dangerous as the victim is a conductor in this case and tou-
ching him could cause electrocution.
Therefore disconnect the contact directly from the power supply valve or, if this
is not possible, distance the victim using insulating material (wooden or pvc
sticks, fabric, leather, etc.).
A doctor should be promptly called and the patient should be taken to the ho-
spital.
1.6.1 - Lighting
Sufficient natural and artificial lighting must be provided around the machine. Li-
ghting must be disposed of in compliance with the laws in force of the country the
machine is installed in.
In any case, lighting must be uniform and guarantee operator visibility in every
point of the machine and it must not create dangerous reflections.
The lighting must enable a clear reading of the control panels and the individuation
of emergency pushbuttons.
