CONTROL FUNCTIONS
MAIN SWITCH
Functions of the respective switch
positions are as follows:
ON:
The engine can be started only at
this position.
OFF:
All electrical circuits are switched off.
Main switch indicator light
The main switch
1 is equipped with
an indicator light
2 to avoid forget-
ting to turn it off. This light functions
as follows.
It lights up with the main switch
“ON”.
It goes out when the engine
increases its speed after being
started.
It lights up again when the engine
is stopped.
NOTE:If the indicator light will not light up
with the main switch “ON”, it shows a
lack of the battery voltage. Recharge
the battery.
ENGINE STOP SWITCH
The engine stop switch
1 is located
on the left handlebar. Continue push-
ing the engine stop switch till the
engine comes to a stop.
START SWITCH
The start switch
1 is located on the
right handlebar. Push this switch to
crank the engine with the starter.

be pulled rapidly and released slowly
for smooth starts.
FONCTIONS DES
COMMANDES
CONTACTEUR A CLE
Les fonctions correspondant aux diffé-
rentes positions du contacteur sont les
suivantes:
ON:
Seule position permettant le démarrage
du moteur.
OFF:
Tous les circuits électriques sont coupés.
Témoin de l’interrupteur à clé
L’interrupteur à clé 1 est équipé d’un
témoin 2 afin de ne pas oublier de le
couper. Ce témoin fonctionne de la
manière suivante.
Il s’allume lorsque l’interrupteur à clé
est en position “ON”.
Il s’éteint lorsque le moteur monte en
régime après le démarrage.
Il se rallume lorsque le moteur est
coupé.
N.B.:
Si le témoin ne s’allume pas lorsque
l’interrupteur à clé est sur “ON”, c’est
que la tension de la batterie est trop fai-
ble. Recharger la batterie.
COUPE-CIRCUIT DU MOTEUR
Le coupe-circuit du moteur 1 est situé
sur la partie gauche du guidon. Appuyer
de façon continue sur le coupe-circuit du
moteur jusqu’à ce que le moteur s’arrête.
CONTACTEUR DU DEMARREUR
Le contacteur du démarreur 1 est situé
sur la partie droite du guidon. Appuyer
sur ce contacteur pour lancer le moteur à
l’aide du démarreur.
LEVIER D’EMBRAYAGE
Le levier d’embrayage 1 est situé sur la
partie gauche du guidon et permet
d’embrayer ou de débrayer. Tirer le
levier d’embrayage vers le guidon pour
débrayer et le relâcher pour embrayer.
Pour un démarrage en douceur, le levier
doit être tiré rapidement et relâché lente-
ment.

GEN
INFO
1. Inspect the coolant level.
2. Turn the fuel cock to “ON”.
3. Push on the main switch to “ON”.
4. Shift the transmission into neu-
tral.
5. Fully open the cold starter knob
1.
6. Start the engine by pushing the
start switch or by kicking the
kickstarter crank.
NOTE:If the engine fails to start by pushing
the start switch, release the switch,
wait a few seconds, and then try
again. Each starting attempt should
be as short as possible to preserve
the battery. Do not crank the engine
more than 10 seconds on any one
attempt. If the engine does not start
with the starter motor, try using the
kickstarter crank.
WARNING
If the starter motor will not turn
when pushing the start switch,
stop pushing it immediately and
kick start the engine in order to
avoid the load on the motor.
Do not open the throttle while
kicking the kickstarter crank.
Otherwise, the kickstarter crank
may kick back.

7. Return the cold starter knob to
its original position and run the
engine at 3,000 ~ 5,000 r/min for
1 or 2 minutes.
NOTE:Since this model is equipped with an
accelerator pump, if the engine is
raced (the throttle opened and
closed), the air/fuel mixture will be
too rich and the engine may stall.
Also unlike a two-stroke engine, this
model can idle.
CAUTION:
Do not warm up the engine for
extended periods of time.1. Contrôler le niveau de liquide de
refroidissement.
2. Placer le robinet de carburant en
position “ON”.
3. Tourner le contacteur à clé sur
“ON”.
4. Mettre la boîte au point mort.
5. Tirer complètement la commande
de départ à froid 1.
6. Démarrer le moteur en appuyant sur
le contacteur du démarreur ou en
actionnant le kick.
N.B.:
Si le moteur ne répond pas au contacteur
du démarreur, relâcher ce dernier, atten-
dre quelques secondes et essayer à nou-
veau. Chaque tentative de démarrage
doit être aussi brève que possible pour
économiser la batterie. Ne pas lancer le
moteur pendant plus de 10 secondes à
chaque tentative. S’il est impossible de
démarrer le moteur à l’aide du démar-
reur, essayer le démarrage au kick.
AVERTISSEMENT
Si le démarreur ne répond pas au
contacteur du démarreur, arrêter
immédiatement d’appuyer sur ce
dernier et démarrer au kick pour
éviter de trop solliciter le moteur.
Ne pas ouvrir le papillon tout en
démarrant au kick car ce dernier
risque de revenir brutalement.
7. Repousser la commande de départ à
froid dans sa position d’origine et
faire tourner le moteur à 3.000 à
5.000 tr/min pendant 1 ou 2 minu-
tes.
N.B.:
Ce modèle étant équipé d’une pompe de
reprise, si le moteur est emballé (ouver-
ture et fermeture du papillon), le
mélange air/carburant sera trop riche et
le moteur risque de caler. A la différence
d’un moteur deux temps, par ailleurs, ce
modèle peut tourner au ralenti.
ATTENTION:
Ne pas faire chauffer le moteur plus
longtemps que nécessaire.
