CONSIGNES GENERALES DE SECURITE
Les consignes spécifiques de prudence et de sécurité mentionnées ici ont pour but de vous informer de la survenance de tout risque de
dommages matériels ou corporels.
ATTENTION!
*Cette machine ne pourra être utilisée que par du personnel parfaitement entraîné et dûment autorisé.
* Evitez les arrêts subits lorsque la machine est chargée et se trouve sur des rampes ou des plans inclinés. Evitez les virages serrés. Adoptez une
vitesse réduite lorsque la machine est en descente. Ne nettoyez que lorsque la machine monte la pente.
*Eloignez les batteries de toutes flammes, étincelles ou substance fumigène. Les gaz explosifs sont ventilés pendant le fonctionnement normal.
*De plus, du gaz hydrogène explosif s’échappe des batteries lorsqu’elles sont en charge. Ne procédez au chargement des batteries que dans une
zone bien ventilée, loin de toute flamme. Ne fumez pas à proximité des batteries lorsqu’elles sont en charge.
*Otez tous vos bijoux lorsque vous travaillez à proximité de composants électriques.
*Positionnez la clé de contact sur off (O) et déconnectez les batteries avant de procéder à l’entretien des composants électriques.
*Ne travaillez jamais sous une machine sans y avoir placé, au préalable, des blocs de sécurité ou des étais destinés à soutenir la machine
*Ne déversez pas d’agents nettoyants inflammables, ne faites pas fonctionner la machine à proximité de ces agents ou d’autres liquides
inflammables.
*Ne nettoyez pas cette machine avec un nettoyeur à pression.
*Utilisez uniquement les brosses fournies avec l’appareil ou celles spécifiées dans le manuel d’instructions. L’utilisation d’autres brosses peut mettre
la sécurité en péril.
PRUDENCE!
* Cette machine n’est pas conçue pour une utilisation sur les chemins ou voies publics.
* Cette machine n’est pas conçue pour le ramassage des poussières dangereuses.
* N’utilisez pas de disques de scarificateur ni de meules. American-Lincoln ne pourra en aucun cas être tenue pour responsable des dommages
occasionnés à vos sols par ce type d’équipement (vous risquez également d’endommager le système d’entraînement des brosses).
* Lors de l’utilisation de cette machine, assurez-vous que des tiers, et notamment des enfants, ne courent pas le moindre risque.
* Avant de procéder à toute opération d’entretien, veuillez lire attentivement toutes les instructions qui s’y rapportent.
* Ne laissez pas la machine sans surveillance sans avoir, au préalable, coupé le contact, enlevé la clé de contact (O) et tiré le frein à main.
* Positionnez la clé de contact sur off (O) avant de remplacer les brosses ou d’ouvrir tout panneau d’accès.
* Prenez toutes les mesures nécessaires pour éviter que les cheveux, les bijoux ou les vêtements amples ne soient entraînés dans les parties
mobiles de la machine.
* Faites attention lorsque vous déplacez cette machine dans un endroit où la température peut descendre sous 0°. Car l’eau contenue dans les
réservoirs de solution ou de récupération ou dans les conduites risquerait de geler et par là même d’endommager les valves et raccords de la
machine. Rincez avec un liquide de lave-glace.
* Prenez soin d’enlever les batteries de la machine avant de mettre cette dernière au rebut. Pour ce qui est de l’élimination des batteries, conformez-
