1.3 - Warranty
The user is not authorized to tamper with the machine for any reason. If
there is a fault contact the manufacturer. Any attempts at dismantling or
tampering with any component of the machine in general by the user or
unauthorized personnel will cause the lapse of the declaration of conformity according to the EEC Directive 89/392, will render the warranty null
and void and the manufacturer will be exempt from any responsibility for
damage to people or things due to such tampering.
The manufacturer is also exempt from all responsibility in the following
cases:
- Incorrect installation;
- Improper use of the machine by inadequately trained personnel;
- Failure to comply with the regulations in force in the country in which
the machine is used;
- Lack of or insufficient maintenance;
- Use of unoriginal spare parts or spare parts not specifically designed
for the model;
- Total or partial failure to follow the instructions.
1.4 - Description of the machine
The grater you have purchased is a simple, compact and powerful machine, with a high yield.
- Since it must be used to grate food products the components that can
come into contact with the product have been carefully chosen to guarantee maximum hygiene.
- The base is made of micro shot-peened stainless steel.
- The inlets have been treated with a buffering procedure to facilitate clea
ning.
- The roller is made of stainless steel to guarantee maximum hygiene
and make it last longer.
- The motor is self-ventilated to keep yield constant during the prolonged
use of the machine.
- The stainless steel extractable sieve (provided upon request) is used to
grate the bread uniformly.
The models represented in this manual have been manufactured in compliance with the EEC Directive 89/392 and modifications thereafter.
In case of an accident the manufacturer cannot be held responsibile if the
machine has been modified or tampered with, if the safety protections ha-
20
5
ve been removed, or if the machine has been used for purposes prohibited
by the manufacturer.
1.5 - Use
The machine has been designed and built to grate cheese, bread or similar products.
It must be used in professional environments and by skilled personnel who
are trained to operate in the sector and have read this manual.
Use the grater only when it is securely placed on a solid work table. The
dimensions of the product must enable it to fit in the loading inlet.
1.6 - Forbidden uses
The machine must only be used for the purposes expressly intended by
the manufacturer. 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
protections 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.

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 touching 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 hospital.
3.4 - Connection to the electrical system
ATTENTION!
Make sure the electrical source corresponds to the value reported on the
identification plate of the machine. Each operation should be carried out
only by specialized personnel authorized by the appropriate supervisor.
