1 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.
