HOW TO READ DESCRIPTIONS
To help identify parts and clarify procedure steps, there are exploded diagrams at the start of each
removal and disassembly section.
1. An easy-to-see exploded diagram
1
is provided for removal and disassembly jobs.
2. Numbers
2
are given in the order of the jobs in the exploded diagram. A number that is
enclosed by a circle indicates a disassembly step.
3. An explanation of jobs and notes is presented in an easy-to-read way by the use of symbol
marks
3
. The meanings of the symbol marks are given on the next page.
4. A job instruction chart

accompanies the exploded diagram, providing the order of jobs,
names of parts, notes in jobs, etc.
5. Extent of removal
5
is provided in the job instruction chart to save the trouble of an unneces-
sary removal job.
6. For jobs requiring more information, the step-by-step format supplements

AUFBAU
Diese Anleitung wurde zusammengestellt, um
dem Benutzer ein leicht verständliches Nach-
schlagewerk in die Hand zu geben, in dem alle
dargestellten Arbeitsvorgänge (Ein- und Aus-
bau, Zerlegung und Zusammenbau, Prüfung
und Reparatur) detailliert und in der entspre-
chenden Reihenfolge beschrieben sind.
Je nach Zustand eines fehlerhaften Bauteils
weist ein Pfeilsymbol auf die erforderliche
Maßnahme hin. Beispiel:
l
Lager
Pitting/Beschädigung
®
Erneuern.
LESEN DER BESCHREIBUNGEN
Um bei der Identifikation der Teile zu helfen
und die Arbeitsschritte zu verdeutlichen, sind
Explosionsdiagramme am Beginn jedes Aus-
bau- und Demontageabschnittes dargestellt.
1. Für die Ausbau- und Demontagearbeiten
ist meistens ein übersichtliches Explosi-
onsdiagramm
1
dargestellt.
2. Die Nummern
2
in dem Explosionsdia-
gramm sind in der Reihenfolge der Arbeiten
aufgeführt. Eine in einen Kreis eingeschrie-
bene Nummer bezeichnet einen Demonta-
geschritt.
3. Eine Erläuterung der Arbeiten und Hinweise
ist durch ablesefreundliche Symbolmarkie-
rungen
3
gegeben. Die Bedeutungen der
Symbolmarkierungen sind auf der nächsten
Seite aufgeführt.
4. Eine Arbeitsanweisungstabelle
4
beglei-
tet das Explosionsdiagramm und gibt die
Arbeitsreihenfolge, Bezeichnung der Teile,
Hinweise zu den Arbeiten usw. an.
5. Der Umfang des Ausbaus
5
ist in der
Arbeitsanweisungstabelle aufgeführt, um
nicht erforderliche Ausbauarbeiten zu ver-
meiden.
6. Für Arbeiten, für die weitere Informationen
benötigt werden, sind schrittweise Ergän-
zungen
6 zusätzlich zu dem Explosions-
diagramm und der
Arbeitsanweisungstabelle aufgeführt.

TIONS
Chaque section détaillant les étapes de démontage
ou de remontage est précédée de vues en éclaté qui
permettent de clarifier ces opérations.
1. Exemple de vue en éclaté 1 clarifiant les opé-
rations de démontage et de remontage.
2. Sur les vues en éclaté, les pièces sont numéro-
tées 2 dans l’ordre des opérations à effectuer.
Un chiffre entouré d’un cercle correspond à une
étape de démontage.
3. Les vues en éclaté portent également des sym-
boles 3 qui rappellent des points importants à
