additional foot mounts
which must be tted
between the feet and
the frame.
The handles are tted
to the right side of the
machine next to the
fuel tank.
Locate the holes and
secure the handles
with the nuts and long
bolts.
The battery is
connected black to
‘-’ negative, red to ‘+’
positive. Secure with
nut and bolt then shield
with terminal covers.
Slot the two axles through the mount and

Consignes de sécurité importantes
• N’essayez en aucun cas de modier la machine.
• Faites régulièrement l’entretien selon le calendrier d’entretien.
• Mettez uniquement du carburant neuf, propre et de bonne qualité dans le moteur.
• Ne faites jamais fonctionner le moteur sans huile.
• Ne faites jamais le plein d’essence à proximité de ammes, d’étincelles ou d’autres sources
d’inammation, comme des cigarettes par exemple.
• Ne faites pas le plein lorsque le moteur est chaud ou que le moteur tourne.
• Essuyez et éliminez correctement et sans attendre tout déversement de carburant conformément aux
directives.
• Éloignez-vous des zones de ravitaillement en carburant avant de redémarrer le moteur. Stocker le
carburant pendant de courtes périodes uniquement dans un récipient approprié, à l’abri de la chaleur
et des rayons directs du soleil.
• Nettoyez le générateur à fond après chaque utilisation.
• Vériez régulièrement les écrous et les xations externes an de vous assurer que les vibrations
(causées par une utilisation normale) ne les aient pas desserrés.
• Videz le réservoir de carburant avant stockage dans un endroit sec et sécurisé, hors de portée des
enfants.
• Ne pas utiliser à l’intérieur
