1. Rules and procedures for Service Centres
This chapter covers all the main aspects of the
relationship between the manufacturer and the
service centres.
A close collaboration between the manufacturer
and the service centres is conclusive for solving
problems in the most effective way as well as
maintaining an image of efficiency and reliability.
Compliance with these brief and simple guidelines
will facilitate this task and prevent general misun-
derstandings and time-wasting for both the manu-
facturer and the service centre.
2. General and safety regulations
This chapter covers the main aspects of a servic-
ing procedure and the general rules for guarantee-
ing a successful service which protects the en-
vironment and respects the safety of both the ser-
viceman and the user of the apparatus.
3. Maintenance
This chapter deals with the criteria for routine
maintenance.
4. Adjustments and tuning
This chapter deals with the adjustments to be ma-
de to remedy the more frequent performance fail-
ures and are usually resolved by quick checks and
tunings.
5. Removal of external parts
and main assemblies
For doing more difficult jobs, greater accessibility
may be required. This can be done by taking the
unit concerned off and working at the bench, or by
removing the cover or other external parts.
Whether or not this will be useful is at the discre-
tion of the mechanic’s experience.
6. Repairs
This chapter deals with all the more complex work
connected with the replacement or repair of mal-
functioning or worn parts.
The descriptions must follow a logical sequence
and can include operations not specifically con-
nected to a particular type of repair.
In this case, careful reading of the entire proce-
dure can help you omit all those operations not
connected with the case in hand without, however,
overlooking anything that may be necessary.
7. Electrical system
This chapter deals with the problems and checks
connected with the electrical system.
All work can be done using a tester without having
to use special equipment.
The electrical diagrams can be useful to you for
understanding how the system functions and to fa-
cilitate the pinpointing of any problems.
8. Technical specifications
This chapter summarises all the main information
regarding the machine.
