Foreword

This is a floor scrubbing machine that is able to clean a wide variety of types of flooring and types of dirt by using the mechanical action of one disk brush and the chemical action of a water-detergent solution. As it moves forward it also gathers up the dirt removed from the floor and the detergent solution that has not been absorbed by the floor. The machine must only be used for this function.
Even the best machines will only operate efficiently and work with profit if they are used properly and kept in perfect operating order.
Read this instruction booklet carefully and consult it every time problems arise with machine operation. Any improper use of the machine is forbidden. Any kind of claim against the producer or his representative for damages due to an use not conformed to machine destination is excluded. Put the manual at operator’s disposal so that he can consult it for all eventualities. Remember that, if necessary, our service organization, in collaboration with our agents, is always available for helpful hints or direct intervention.
