Fonction
L'aspirateur à abrasion sert au nettoyage humide ou au polissage de sols plans. Il est facile d'adapter l'appareil à la tâche de nettoyage à accomplir en réglant la quantité d'eau, la pression des brosses, la quantité de détergent ainsi que la vitesse de transport.
Utilisation conforme
Cet appareil convient à un usage professionnel et industriel, par exemple dans le cadre d'hôtels, d'écoles, d'hôpitaux, d'usines, de magasins, de bureaux et d'agences de location.
L'utilisation de l'appareil doit être faite en conformité avec les consignes figurant dans les instructions de service. L'appareil doit uniquement être utilisé
pour nettoyer des surfaces planes non sensibles à l'humidité ni au polissage. Cet appareil est destiné à une utilisation dans les locaux intérieurs. La plage de température pour l'utilisation est de +5°C à +40°C. L'appareil n'est pas approprié pour nettoyer des sols gelés (par exemple dans des entrepôts frigorifiques) L'appareil convient à une hauteur d'eau maximum de 1 cm. Ne pas rouler dans une zone dans laquelle la hauteur d'eau maximum risque d'être dépassée. L'appareil doit uniquement être équipé d'accessoires et de pièces de rechange d'origine. L'appareil n'est pas destiné au nettoyage de voies publiques. L'appareil ne peut être utilisé sur des sols qui sont sensibles à la pression. Tenir compte de la sollicitation concentrée admissible du sol. La charge concentrée par l'appareil est indiquée dans les données techniques. L'appareil n'est pas approprié pour l'application dans des environnements à risque d'explosion. Ne pas aspirer avec l'appareil des gazes combustibles, acides ou solvants non dilués. Ces-ci sont essence, dilutif de couleurs ou fuel, qui peuvent former des mélanges explosives en touillant avec l'air d'aspiration. Ne pas utiliser d'acétone, d'acides ou de solvants non dilués, du fait de leur effet corrosif sur les matériaux constituant l'appareil.
