INTRODUCTION
Thank you for having chosen our machine. This floor cleaning machine is used for the industrial and civil cleaning and is able to clean any type of
floor. During its advance movement, the combined action of the brush and the detergent solution removes the dirt which is aspirated through the
rear suction assembly, giving a perfectly dry surface.
The machine must be used only for such purpose. It gives the best performance if it is used correctly and maintained in perfect efficiency. We
therefore ask you to read this instruction booklet carefully whenever difficulties arise in the course of the machine’s use. In case of need, we ask you
to contact our service department for all advice and servicing as may prove necessary.
