introduction
This publication is intended for the trained technician who must operate on our tractors.
It contains all general information relating to our tractor range, and in particular it highlights the inspection, overhauling
and adjustment procedures as well as the main instructions for dismantling and reassembling operations.
The workshop manual is a natural summary for the mechanic who has attended the vocational training and
specialization courses, which are held every year at our Service School, to permit him to perform a precise and qualified
work on tractor.
Its contents are therefore an exhaustive reference book for the experienced mechanic who desires to refresh his
memory on the sequence of the operations to be done. It is then good practice for every authorized dealer mechanic
to have at his disposal this publication, so that it may be consulted quickly when necessary.
We wish to thank in advance for the cooperation all thos people, who will let us have their suggestions in order to make
this publication more complete.
