und Wartungsarbeiten verweisen wir auf die Be-
triebsanleitungen.
Von den Werkstätten sind die Technischen Daten
zu beachten.
Die einschlägigen Unfallverhütungsvorschriften
sowie die sonstigen allgemeinen anerkannten si-
cherheitstechnischen und arbeitsmedizinischen
Regeln sind einzuhalten.
Dieses Werkstatthandbuch unterliegt keinem Ände-
rungsdienst, wir weisen aus diesem Grunde auf die
zusätzlich herauskommenden technischen Rund-
schreiben besonders hin. Bei Neuauflage eines
Werkstatthandbuches werden alle Änderungen
berücksichtigt und mit eingearbeitet.
Gegenüber Darstellungen und Angaben dieses
Werkstatthandbuches sind technische Änderungen,

PREMESSA
Il presente manuale è stato redatto per le officine
dei nostri concessionari e contiene tutte le
indicazioni relative allo smontaggio ed al montaggio
che si rendono necessari per la registrazione e la
sostituzione di ricambi.
Se ci sono parti da sostituire devono essere
utilizzati assolutamente ricambi originali. I ricambi
devono venire ordinati indicando il numero di telaio,
secondo la documentazione ricambistica in vigore.
E‘ necessario che questi lavori vengano effettuati da
personale specializzato, perciò le riparazioni
generalmente note non sono descritte in questo
manuale.
Si presuppone la presenza degli attrezzi necessari e
di dispositivi in generale che fanno parte della
dotazione di un‘officina.
Attrezzi speciali sono limitati al minimo
indispensabile e vengono elencati alla fine di questo
manuale. Per quanto riguarda la manutenzione si
prega di consultare le istruzioni per l‘uso.
Le officine devono osservare i dati tecnici.
Rispettare le norme antinfortunistiche nonché le
generali norme tecniche sulla sicurezza e di
medicina sul lavoro.
Questo manuale non è soggetto a nessun servizio
di aggiornamento, per questo motivo rimandiamo ad
ulteriori comunicazioni tecniche. In caso di
aggiornamento di un manuale si tiene conto delle
variazioni, che vengono poi incluse nella nuova
versione.
Ci riserviamo il diritto di apportare modifiche rispetto
ad illustrazioni ed indicazioni di questo manuale,
che si rendono necessarie per il miglioramento del
prodotto. Stampa e riproduzione di ogni genere,
anche parziale, di questo manuale solo previa
nostra autorizzazione scritta.

VOORWOORD
Dit werkplaatshandboek werd samengesteld voor
de werkplaatsen van onze dealers en bevat de
beschrijving van alle demontage- en
montagehandelingen die in combinatie met
afstelwerkzaamheden en het vervangen van
onderdelen nodig zijn.
Moeten bepaalde onderdelen worden vervangen,
dan mogen alleen originele reserve-onderdelen
worden gebruikt. Bestellingen van onderdelen kunt
u plaatsen onder vermelding van het
chassisnummer overeenkomstig de geldige
onderdeeldocumentatie.
Wij gaan ervan uit dat deze werkzaamheden door
vakkundige mensen worden uitgevoerd; daarom
staan in dit handboek geen beschrijvingen van
algemeen bekende reparaties.
In de handel verkrijgbaar gereedschap en algemene
apparaten die tot de inventaris van de werkplaats
behoren, zijn hierbij eerste vereiste.
Speciaal gereedschap is tot het meest
noodzakelijke beperkt en wordt aan het eind van het
boek in een samenvatting weergegeven. Wat betreft
de verzorgings- en onderhoudswerkzaamheden
verwijzen we naar de trekkerhandleidingen.
De werkplaatsen moeten rekening houden met de
technische gegevens.
De geldende ongevallenpreventievoorschriften
alsmede de overige algemeen erkende
veiligheidstechnische en bedrijfsgeneeskundige
regels moeten in acht genomen worden.
Bij veranderingen wordt dit werkplaatshandboek niet
aangepast; wij wijzen daarom in het bijzonder op de
extra uitgegeven technische infobladen. Bij een
nieuwe oplage van een werkplaatshandboek wordt
er rekening gehouden met alle wijzigingen en in het
boek verwerkt.
Tegenover weergaven en gegevens in dit
werkplaatshandboek zijn technische wijzigingen, die
voor verbetering van het product noodzakelijk zijn,
voorbehouden. Voor nadruk en vermenigvuldiging
op welke wijze ook, ook een uittreksel of
samenvatting, heeft u onze schriftelijke
toestemming nodig.

Documentation structure
Text-module
The basic principle of this documentation is that the different tractor types are divided into main assem-
blies, which correspond to the FENDOS structure with a few exceptions for technical reasons.
These main assemblies are, for example, "0000 - Tractor/General system" ; "1000 - Transmission";
"2000 - Engine", etc.
The main assemblies are sub-divided into subassemblies, e.g. "1005 - Transmission control unit";
"1220 - Live PTO", etc.
Please see document 0000 A 000009 for an overview of the assemblies.
Each assembly is subdivided into various registers which are labelled with an index letter.
These are as follows.
This documentation is made up of a large number of self-contained individual documents
(=worksheets). These documents can be used for various applications and are available in
different languages.
Each document is given a unique document code (8), which is made up of the chapter no. (1)
(=assembly / subassembly), the index letter (2), and the document no. (3), printed on the right of the
footer.
A document can, therefore, be clearly assigned to a main assembly/subassembly and the index.
