Maintenance intervals
All the components requiring maintenance are accessible from the front or the rear panel of the appliance.
The inspection and maintenance intervals depend on the actual machine operation conditions and ambient conditions (presence of
dust, damp, etc.), therefore precise time intervals cannot be given.
In any case, careful and periodical machine maintenance is advisable in order to minimise service interruptions.
To ensure constant machine efficiency, it is advisable to carry out the checks with the frequency given in the following table:
IMPORTANT
Machine maintenance, checking and overhaul operations must only be carried out by a specialised Technician or the
Customer Care Service, provided with adequate personal protection equipment (safety shoes and gloves), tools and
ancillary means;
Work on the electrical equipment must only be carried out by a specialised electrician or the Customer Care Service.
