6.7. Components subject to wear and tear
Attention
Components subject to wear and tear due to
their function must be periodically checked and
replaced when they show noticeable signs of
wear.
The manufacturer has designed and built the machine
to last for a reasonable amount of time taking into
consideration its intended use; it is nevertheless
necessary to periodically carry out checks to verify the
state of the components subject to wear and tear.
If structural deformations or fissures in the metallic
components or in the soldering are found, immediately
contact the manufacturer’s customer service; the
expert technicians will help you to take the necessary
steps.
Due to their manufacturing properties, heating
elements undergo a reduction of their isolating
properties over time, particularly when exposed to a
high level of humidity. Periodically check the
functioning of the circuit breaker, provided for the
protection of the machine.
All electrical components having mechanical moving
parts during the working cycle (buttons, relays, etc.)
are guaranteed by the manufacturer for a high, but
always limited, number of cycles.
Periodical cleaning of the inner part of the electric
panel prevents these elements from being subject to
further mechanical fatigue.
6.8. Planned preventive maintenance
Thanks to the correct use of the machine and to the
appropriate planned preventive maintenance it is
possible to obtain the highest reliability from the
machine
at a minimum maintenance cost.
Furthermore, through periodic checks, mechanical or
electrical faults will come to light before these cause
damage to the machine or pose risks to personnel.
Note
Strictly respect the maintenance time intervals
and space them out according to the specific
necessities in relation to the productive cycle of
the machine.
Here below is a list of periodic checks suggested by
the manufacturer:
Before and at the end of each working cycle:
Cleaning of the external parts of the machine (see
section 6.4)
Before starting each working cycle:
Check that the emergency stop button is functioning
correctly:
press the emergency stop button while the
machine is switched on and check that the main switch
trips, cutting off the power to the machine.
Check that the grill safety micro switch is functioning
correctly:
lift the grill while the machine is switched on
and check that the main switch trips, cutting off the
power to the machine.
Every month:
Check the state of the internal components of the
machine:
follow the instructions given in section 6.5.1,
remove one of the lateral fixed protective panels and
check that there are no signs of humidity inside the
machine induced by other nearby machines.
Check the level of the cooling liquid:
Follow the instructions given in section 6.5.2
Every six months:
Check that the safety micro switch of the electric panel
door is functioning correctly:
open the door of the
electric panel while the machine is switched on, check
if the main switch trips, cutting off the power to the
machine.
Check the state of the mechanical fixings of the internal
components:
follow the instructions given in section
6.5.1, remove the lateral and rear fixed protective
panels and check, by using the appropriate tools, that
the components’ fixing screws are not loose.
Purging the cooling liquid system:
follow the instructions given in section 6.5.3
Warning
The manufacturer suggests carrying out a full
service every two years to maintain the safety
aspects of the machine over time.
Note
The machine is for professional use: it is therefore
necessary to strictly respect the legislation in force
regarding the periodic checks to the electrical
circuits.
The manufacturer recommends the logging of all
planned
maintenance and extraordinary
interventions, including dates and reasons for
the interventions.
