Safety and Warranty
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
4
Safety and Warranty
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, rst 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.
ATTENTION!
Do not intervene on electrical parts while the machine is connected to the power supply.
Observe the warnings on the plates. Failure to observe them can cause serious injury.
Make sure the plates are always tted and readable. If not, t or replace them.
ATTENTION!
Before using the machine make sure that the devices are correctly positioned and in perfect working
order.
At the beginning of each work shift check that they are tted and working properly; if not, notify the
head of maintenance.
MICROSWITCH ON THE LEVER
The machine is outtted with a microswitch on the lever of the inlet. This works by blocking the machine when
the lever remains lifted or the inlet is completely disassembled.
MICROSWITCH ON THE CONTAINER
The machine is outtted with a microswitch on the plexiglass container. When the container is extracted the
machine stops.
ATTENTION!
Do not tamper with the safety devices in any way.
