The machine is designed for temperatures of between +4°C and +35°C when in use and between +0°C and
+50°C when not in use.
The machine is designed to work in a humidity of between 30% and 95%.
Never use or pick up flammable liquids or explosives (e.g. petrol, fuel oil, etc), flammable gases, dry dusts, acids
and solvents (e.g. paint solvents, acetone etc) even if diluted. Never pick up flaming or incandescent objects.
Never use the machine on slopes or ramps of more than 2%. In the case of slight slopes, do not use the machine
transversally, always manoeuvre with care and do not reverse. When transporting the machine on steeper ramps
or slopes, take the utmost care to avoid tipping up and/or uncontrolled acceleration. Tackle ramps and/or steps
with the front of the machine raised only.
Never park the machine on a slope.
The machine must never be left unattended with the motor or engine on. Before leaving it, turn the motor or engine
off, make sure it cannot move accidentally.
Always pay attention to other people, children in particular, present in the place where you are working.
Children must be supervised to make sure they do not play with the appliance.
The appliance is not intended for use by persons (including children) with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concer-
ning use of the appliance by a person responsible for their safety.
Never use the machine to transport people or things or to tow things. Do not tow the machine.
Never rest objects of any weight on the machine for any reason.
Never obstruct ventilation and heat dispersion slits.
Never remove, modify or circumvent safety devices.
Numerous unpleasant experiences have shown that a wide range of personal objects may cause serious acci-
dents. Before beginning work, remove jewellery, watches, ties, etc.
The operator must always use personal protection devices - protective apron or overalls, non-slip waterproof
shoes, rubber gloves, protective goggles and ear protectors and mask to protect the respiratory tract.
Keep the hands away from moving parts.
Never use detergents other than those specified. Follow the instructions on the relative safety sheet. We recom-
mend keeping detergents out of reach of children. In the event of contact with the eyes, wash immediately with
abundant water. If ingested, consult a doctor immediately.
Make sure the power sockets used for the models with cable or battery charger are connected to a suitable earth
system and protected by differential thermal solenoid switches.
Make sure the electrical characteristics of the machine (voltage, frequency, absorbed power) given on the rating
plate are the same as those of the mains electricity supply. The machine with cable has a three-wire cable and a
three pin earthed plug for use in an appropriate earthed socket. The earth wire is yellow and green. Never connect
this wire to anything other than the earth contact of the socket.
It
is
indispensable
to
respect
the
battery
manufacturer's
instruc-
tions
and
current
legislation.
The
batteries
should
always
be
kept
clean
and
dry to avoid surface leakage current. Protect the batteries from impurities such as metal dust.
Never rest tools on the batteries as this could cause short circuit and explosion.
When using battery acid, always follow the relative safety instructions scrupulously.
When using cable models, take care not to crush or pull the power supply cable.
While using the machine, make sure the rotating brush does not come in contact with the power cable (cable
powered version).
Check the power cable regularly. If damaged, do not under any circumstances use the machine. Replace it with
one of the same type or contact a specialised service centre (cable powered version).
In the presence of particularly strong magnetic fields, assess the possible effect on the control electronics.
Never wash the machine with water jets.
The fluids collected contain detergent, disinfectant, water and organic and inorganic material. They must be dispo-
sed off in accordance with current legislation.
In the case of malfunction and/or faulty operation, turn the machine off immediately (disconnecting it from the
mains power supply or batteries) and do not tamper. Contact a service centre authorised by the Manufacturer.
All maintenance operations must be performed in an adequately lit place and only after disconnecting the ma-
chine from the power supply, in cable models by unplugging the machine from the socket, in battery models by
disconnecting the battery connector; in cable models, the operator must be able to verify from any position that the
machine remains unplugged from the mains socket while maintenance is being carried out.
In general, in an emergency, power to the machine can be quickly disconnected (battery version) by removing
the fuse (fig. L).
All work on the electrical system and all maintenance and repair operations other than those explicitly
described in this manual must be performed by specialised personnel expert in the sector only.
If the power cable, plug or terminals require replacing, make sure the electrical connections and cable grip are
tightly fastened to guarantee the resistance of the cable if pulled. Only original accessories and spare parts sup-
plied by the Manufacturer may be used in order to guarantee safe problem-free operation of the machine. Never
