3. Maintenance
This chapter covers the main aspects of a servi c­
ing procedure.
A specific chapter is dedicated to a quick trouble­
shooting guide on the most frequent questions
and the chapter references providing information
on the interventions required to resolve the same.
4. Adjustments and tuning
his chapter deals with the adjustments to be ma de
to remedy the more frequent performance fai lures
and are usually resolved by quick checks and tun­
ings.
5. Removal of external parts and main assem-
blies
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 procedure
can help you omit all those operations not connect­
ed with the case in hand without, however, over­
looking anything that may be necessary.
7. Electrical system
This chapter deals with the problems and checks
con nect ed with the electrical system.
All work can be done using a tester without ha ving
to use special equipment.
