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 qualied 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
clarications.
This manual is written both for operators and for qualied machine maintenance technicians. Operators must not perform operations that
should be carried out by qualied technicians. The manufacturer is not liable for damages resulting from failure to comply with this veto.
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.
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 ofce. 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
INTENDED USE
SAFETY
SERIAL NUMBER PLATE
The ULTRA 120 is a oor scrubbing machine that can handle a wide variety of oors and types of dirt by using the mechanical action of two
disc brushes and the chemical action of a water-detergent solution. As it advances, it collects the dirt removed and the detergent solution not
absorbed by the oor. The machine must only be used for this purpose.
This scrubbing machine was designed and built for the cleaning (scrubbing and drying) of smooth, compact ooring in the commercial,
residential and industrial sectors by a qualied operator in proven safety conditions. The scrubbing machine is not suitable for cleaning rugs
or carpets. 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 inammable liquids in places with an explosive atmosphere.
In addition, it is not suitable as a means of transport for people or objects.
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. The manufacturer declines responsibility for any possible injury.
The serial number plate is located underneath the command panel. It
indicates 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 when purchasing spare parts.
INTRODUCTORY COMMENT
Any oor 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 difculties 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.

paragraph of the instruction manual. The use of other brushes
could be unsafe.

16
• The machine must only be powered with a voltage equal to that
shown on the serial number plate. (B versions).
• If the machine is left unattended, it must be protected from any
accidental movements.
• The machine must be regularly inspected by a qualied person,
especially with regards the LPG tank and its connections, as
required by local or national safety regulations.
• When replacing the LPG cylinder, stay far from ames, cinders
or active electric devices. Before replacing it, make sure the
taps of both the old and the new cylinders are turned off (G bi-
fuel versions).
• The seal between the tap and the regulator must be changed
every time the cylinder is changed (G bi-fuel versions).
• After replacing the cylinder, carry out a seal test on the
connections using soapy water (never use ames for this
purpose). After this, perform a machine switch-on test (G bi-
fuel versions).
• If you smell gas, turn off the supply (cylinder tap); air the room
well, bearing in mind that LPG is heavier than air and spreads
at ground level. Have the system checked by specialised
personnel (G bi-fuel versions).
• After every use, turn off the cylinder valve tap (G bi-fuel
versions).
• Non-connected cylinders - whether full, partially full, empty or
presumed empty - must never be kept on the user's premises
(G bi-fuel versions).
• The refuelling place must be well aired. Never refuel the engine
inside a building where the gasoline fumes could come into
contact with ames or sparks.
• Do not refuel when the engine is still hot.
• You are advised to always put on protective gloves before

17
handling the fuel, to avoid any risk of serious injury to your
hands.
