INTRODUCTORY COMMENT
Thank you for having chosen our machine. This floor-cleaning machine is used for industrial and
commercial cleaning and is able to clean any type of floor. During its forward movement, the combined
action of the brush and the detergent solution removes the dirt that is aspirated through the rear suction
assembly, giving a dry surface.
The machine must be used only for such purposes. It gives the best performance if it is used correctly and
maintained in perfect condition. We therefore ask you to read this instruction booklet carefully whenever
difficulties arise in the course of the machine’s use.
