PURPOSE AND CONTENT OF THE MANUAL

TARGET GROUP

The aim of this manual is to provide customers with all the information needed to use the machine 

in the safest, most appropriate and most autonomous way. This includes information concerning 

technical aspects, safety, operation, downtime, maintenance, spare parts and scrapping. The operators 

and qualified technicians must carefully read the instructions in this manual before carrying out any 

operations on the machine. If in doubt about the correct interpretation of instructions, contact your 

nearest Customer Service Centre to obtain the necessary clarifications.

This manual is written both for operators and for qualified machine maintenance technicians. Operators 

must not perform operations that should be carried out by qualified technicians. The manufacturer is not 

liable for damages resulting from failure to comply with this veto.

STORING THE USE AND MAINTENANCE MANUAL

The Use and Maintenance Manual must be stored in its special pouch close to the machine, protected 

from liquids and anything else that could compromise its legibility.

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.

IDENTIFICATION DATA

For technical assistance or to request replacement parts, always give the model, the version and the 

serial number (written on the relevant plate).

TECHNICAL DESCRIPTION

The 

TRIDENT T20SC PRO

 is a floor scrubbing machine that can work on various types of floor and dirt 

thanks to the mechanical action of a brush and the chemical action of a water-detergent solution. As 

it advances, it collects the dirt removed, along with the detergent solution not absorbed by the flooring 

itself. 

The machine must only be used for this purpose

.

INTENDED USE

This scrubbing machine was designed and built for the cleaning (scrubbing and drying) of smooth, 

compact flooring in the commercial, residential and industrial sectors by a qualified operator in proven 

safety conditions. The scrubbing machine is not suitable for cleaning rugs or carpet floors.  It is only 

suitable for use in closed (or at least covered) places.

ATTENTION:

 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 in 

places with an explosive atmosphere. In addition, it is not suitable as a means of transport for 

people or objects.

SAFETY

Operator cooperation is paramount for accident prevention. No accident prevention programme can 

be effective without the full cooperation of the person directly responsible for machine operation. The 

majority of occupational accidents that happen either in the workplace or whilst moving are caused by 

failure to respect the most basic safety rules. An attentive, careful operator is most effective guarantee 

against accidents and is fundamental in order to implement any prevention programme.

INTRODUCTORY COMMENT

Any floor scrubbing machine can only work properly and effectively if used correctly and kept in full 

working order by performing the maintenance operations described in the attached documentation. 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 assistance service (organised in collaboration 

with our dealers) is always available for advice or direct intervention.

CONVENTIONS

All references to forwards and backwards, front and rear, right and left indicated in this manual should 

be understood as referring to the operator in the driving position, with his/her hands on the control 

handlebars.

Symbol of the squeegee body vacuum tube position:

Used to indicate the correct position of the squeegee body vacuum tube. The tube must 

be positioned behind the squeegee body lifting chain.

SERIAL NUMBER PLATE

The serial number plate is located above the electric system panel, inside the machine. It shows the 

general machine characteristics, in particular the serial number. 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.
