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
ascertain the extent of the damage at once, informing our customer
service office. It is only by prompt action of this type that the missing
material can be obtained, and compensation for damage successfully
claimed.
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 - locations.
The machine is not suitable for use in the rain, or under water jets. It is
FORBIDDEN to use the machine for picking up dangerous dusts or
inflammable liquids within places with a potentially explosive atmosphere.
In addition, it is not suitable as a means of transport for people or objects.
Introductory comment
The TRIDENT B20SC is a floor scrubbing machine which, by means of
the mechanical action of the rotating brush and the chemical action of a
water/detergent solution, can clean any type of flooring. As it advances, it
also collects any removed dirt as well as the detergent solution not
absorbed by the floor.
The machine must only be used 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.
