CONTROL FUNCTIONS
FUEL COCK
The fuel cock supplies fuel from the tank to
carburetor while filtering the fuel. The fuel cock
has the three positions:
OFF: With the lever in this position, fuel will not
flow. Always return the lever to this posi-
tion when the engine is not running.
ON: With the lever in this position, fuel flows
to the carburetor. Normal riding is done
with the lever in this position.
RES: This indicates reserve. If you run out of
fuel while riding, move the lever to this
position. FILL THE TANK AT THE FIRST
OPPORTUNITY. BE SURE TO SET
THE LEVER TO “ON” AFTER REFUEL-
ING.
STARTER LEVER (CHOKE)
When cold, the engine requires a richer air/fuel
mixture for starting. A separate starter circuit,
which is controlled by the starter lever 1, sup-
plies this mixture.
Pull the lever out to open the circuit (for start-
ing) and push the lever in to close the circuit.
FUEL TANK CAP
Remove the fuel tank cap 1 by turning
counter-clockwise.
WARNING
Do not overfill the fuel tank. Avoid spilling
fuel on the hot engine.

TOOL KIT
Spark plug wrench
Spark plug wrench 1 is used to remove and
install the spark plug.

KRAFTSTOFFHAHN
Der Kraftstoffhahn leitet den Kraftstoff vom
Tank zum Vergaser und filtert ihn gleichzeitig.
Die drei Kraftstoffhahn-Stellungen sind nach-
folgend beschrieben.
OFF: In dieser Stellung ist der Kraftstoffhahn
geschlossen und die Kraftstoffzufuhr
unterbrochen. Der Kraftstoffhahn sollte
nach Abstellen des Motors in diese Stel-
lung gebracht werden.
ON: In dieser Stellung wird der laufende
Motor mit Kraftstoff versorgt. Diese Stel-
lung ist für den Normalbetrieb.
RES: Dies ist die Reservestellung. Geht wäh-
rend der Fahrt der Kraftstoff aus, den
Kraftstoffhahn in diese Stellung bringen.
SO BALD WIE MÖGLICH AUFTANKEN.
NACH DEM TANKEN SOLLTE DER
KRAFTSTOFFHAHN WIEDER AUF
“ON” GESTELLT WERDEN.
CHOKEHEBEL
Ein kalter Motor benötigt zum Starten ein fette-
res Luft-Kraftstoff-Gemisch. Dies wird von
einer speziellen Kaltstarteinrichtung geliefert,
die der Chokehebel 1 betätigt.
Zum Betätigen des Chokes den Hebel heraus-
ziehen, zum Abstellen des Chokes den Hebel
zurückschieben.
TANKVERSCHLUSS
Den Tankverschluss 1 im Gegenuhrzeiger-
sinn abdrehen.
WARNUNG
Den Kraftstofftank niemals überfüllen. Dar-
auf achten, dass kein Kraftstoff auf den hei-
ßen Motor verschüttet wird.
BORDWERKZEUG

Der Zündkerzenschlüssel 1 dient zum Aus-
und Einbau der Zündkerze.

Dieses Werkzeug dient zur Ausführung ver-
schiedener Wartungs- und Reparaturarbeiten.
FONCTIONS DES COMMANDES
BEDIENUNGSELEMENTE UND DEREN FUNKTION
ROBINET DE CARBURANT
Le robinet de carburant amène le carburant du
réservoir au carburateur tout en le filtrant. Il a trois
positions:
OFF: Lorsque le robinet est dans cette position,
l’arrivée de carburant est coupée. Toujours
replacer le robinet dans cette position après
avoir coupé le moteur.
ON: Lorsque le robinet est dans cette position, le
carburant parvient au carburateur. Pour rou-
ler, le robinet doit se trouver dans cette posi-
tion.
RES: Position de réserve. Si le carburant vient à
manquer au cours d’une randonnée, placer le
levier dans cette position. FAIRE LE PLEIN
DES QUE POSSIBLE. NE PAS OUBLIER
DE REMETTRE LE LEVIER SUR “ON”
APRES AVOIR FAIT LE PLEIN.
LEVIER DE STARTER
Quand il est froid, le moteur a besoin d’un mélange
air - carburant plus riche pour démarrer. Un circuit
de démarrage séparé, commandé par le levier de
starter 1, fournit ce mélange.
Tirer sur le levier pour ouvrir le circuit (pour la
mise en marche) et repousser le levier pour refer-
mer le circuit.
BOUCHON DU RESERVOIR DE
CARBURANT
Retirer le bouchon du réservoir de carburant 1 en
le tournant dans le sens inverse des aiguilles d’une
montre.
AVERTISSEMENT
Ne pas trop remplir le réservoir de carburant. Evi-
ter de renverser du carburant sur le moteur chaud.
