INTRODUCTION
−This manual is divided into sections identified by two−figure numbers and each section has independent
page numbering.
For easy reference, these sections have the same numbers and names as the Repairs Rate Book sections.
−The different sections can easily be found by consulting the table of contents on the following pages.
−The document number of the manual and the edition/update dates are given at the bottom of each page.
−Pages updated in the future will be identified by the same document number followed by an additional digit:
first edition standard manual 84131814A −1st update 84131814A1 −2nd update 84131814A2 −etc.
The update pages can replace or supplement the pages of the standard manual; the information necessary
for the procedure for adding or replacing pages is given on the title page of the update.
The publication will be completed with an appropriate index.
If it is necessary to issue a new updated manual (2nd edition) it will have document number 84131814B, this
indicates that the manual is composed of the standard version 84131814A completed with all the updates:
1st update 84131814A1 −2nd update 84131814A2 −etc.
−The information contained in this manual was current on the date printed on each section. As
NEW HOLLAND constantly improves its product range, some information may be out of date subsequent
to modifications implemented for technical or commercial reasons, or to meet legal requirements in different
countries.
In the event of conflicting information, consult the NEW HOLLAND Sales and Service Departments.
