ON CONSIGNMENT OF THE MACHINE
When the machine is consigned to the customer, an immediate check
must be performed to ensure all the material mentioned in the shipping
documents has been received, and also to check the machine has not
suffered damage during transportation. If this is the case, the carrier
must note the extent of the damage at once, informing our customer
service office at the same time. It is only by prompt action of this type
that the missing material can be obtained, and compensation for
damage successfully claimed.
INTRODUCTORY COMMENT
Optima is a scrubbing machine that is able to clean a wide variety of
types of flooring and types of dirt by using the mechanical action of two
disc or cylindrical brushes and the chemical action of a water-detergent
solution. As it advances, it also collects the dirt removed and the
detergent solution not absorbed by the floor.
The machine must be used only for this purpose. Even the best
machines will only work well if used correctly and kept in good working
order. We therefore suggest you read this instruction booklet carefully
and read it again whenever difficulties arise while using the machine. If
necessary, remember that our customer assistance service (organised
in collaboration with our dealers) is always available for advice or direct
intervention.
INTENDED USE
The floor scrubbing machine is designed exclusively for the professional
cleaning of surfaces and floors in industrial, commercial and public
environments. The machine is only suitable for use in closed (or at least
covered) places.
The machine is not suitable for use in the rain, or under water jets.
It is FORBIDDEN to use the machine to pick up dangerous dusts or
inflammable liquids
in places with an explosive atmosphere. In addition, it is not
suitable as a means of transport for people or objects.
SERIAL NUMBER PLATE
The serial number plate is located at the rear of the steering column,
and indicates the general characteristics of the machine, in particular the
serial number of the machine. The serial number is a very important
piece of information and should always be provided together with any
request for assistance or to purchase spare parts.
