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.
