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:
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.
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:
remove the lateral and rear
fixed protective panels and check, by using the
appropriate tools, that the components’ fixing screws
are not loose.
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.
