INFO
8. Alle lackierten und verchromten Oberflä-
chen mit Pflegewachs behandeln. Keine
Pflegemittel mit Scheurmitteln verwenden,
um Kratzer zu vermeiden.
9. Anschließend den Motor anlassen und
einige Minuten lang betreiben.
LAGERUNG
Soll das Motorrad länger als 60 Tage gelagert
werden, sind gewisse Schutzmaßnahmen not-
wendig. Das Motorrad nach der Wäsche, wie
nachfolgend beschrieben, auf die Lagerung
vorbereiten:
1. Das Benzin aus dem Kraftstofftank ablas-
sen und den Vergaser entleeren.
2. Die Zündkerze herausdrehen, einen Ess-
löffel SAE 10W-30-Motoröl in die Zündker-
zenbohrung gießen und die Zündkerze
wieder eindrehen. Bei betätigtem Motor-
stoppschalter mehrmals den Kickstarterhe-
bel durchtreten, um die
Zylinderwandungen mit Öl zu bedecken.
3. Die Antriebskette abnehmen, gründlich rei-
nigen und anschließend schmieren. Die
Kette montieren oder in einem am Rahmen
angebundenen Plastikbeutel aufbewahren.
4. Sämtliche Seilzüge ölen.
5. Das Motorrad so abstützen, dass die
Räder sich frei drehen lassen.
6. Einen Plastikbeutel über die Schalldämp-
feröffnung binden, damit keine Feuchtigkeit
eindringt.
7. Ist der Lagerort feucht oder salzhaltig,
sämtliche Metallflächen mit Sprühöl behan-
deln. Öl von Gummiteilen und der Sitzbank
fern halten.
HINWEIS:
Anfallende Reparaturen oder Inspektion vor
der Stilllegung ausführen.
NETTOYAGE ET REMISAGE
PFLEGE UND LAGERUNG
8. Une cire pour carrosserie peut être utilisée pour
toutes les surfaces peintes et chromées. Ne pas
employer de cires détergentes car elles contien-
nent souvent des abrasifs.
9. Lorsque le nettoyage est terminé, mettre le
moteur en marche et le laisser tourner au ralenti
pendant plusieurs minutes.
REMISAGE
Si la moto doit être remisée pour 60 jours ou plus, il
convient de prendre certaines précautions pour évi-
ter tout endommagement. Après un nettoyage com-
plet de la moto, la préparer comme suit pour le
remisage:
1. Vidanger le réservoir de carburant, le circuit de
carburant et la cuve à niveau constant du carbu-
rateur.
2. Déposer la bougie, verser une cuillère à soupe
d’huile moteur SAE 10W-30 dans le trou de
bougie et replacer la bougie. Enfoncer le coupe-
circuit du moteur et lancer quelques fois le
moteur à l’aide du kick afin de répartir l’huile
sur les parois du cylindre.
3. Déposer la chaîne de transmission, la nettoyer
soigneusement à l’aide d’un solvant puis la
graisser. Remettre en place la chaîne ou la con-
server dans un sachet en plastique (attaché au
cadre pour éviter de l’égarer).
4. Lubrifier tous les câbles de commande.
5. Placer un support sous le cadre afin de suréle-
ver les deux roues.
6. Couvrir la sortie du tuyau d’échappement d’un
sachet en plastique pour empêcher la pénétra-
tion d’humidité.
7. Si la moto doit être remisée dans un lieu très
humide ou exposé à l’air marin, enduire toutes
les surfaces métalliques extérieures d’une fine
couche d’huile. Ne pas enduire d’huile les par-
ties en caoutchouc et la housse de selle.
N.B.:
Effectuer toutes les réparations nécessaires avant de
remiser la moto.
