Never use the machine on slopes or ramps of more than 16%. 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. Move the machine on ramps and/or steps
only with the brush head and squeegee raised.
Never park the machine on a slope.
The machine must never be left unattended with the motors on. Before leaving it, turn the
motors off, make sure it cannot move accidentally and disconnect the electrical power
supply.
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 machine
The machine is not intended for use by persons (including children) with reduced physical,
sensory or mental capabilities, or lack of experience and knowledge, unless they are
supervised by a person responsible for their safety and have received instruction in the
use of the machine.
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 accidents. 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 recommend 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 battery charger are connected to a suitable
earth system and protected by differential thermal solenoid switches.
Battery charger (OPTIONAL): check the power cable regularly for damage; if damaged,
do not use the machine. For replacement, contact a specialised service centre.
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 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 instructions 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.
To recharge the batteries, always use the battery charger supplied with the machine
(when provided).
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 disposed off in accordance with current legislation.
In the case of malfunction and/or faulty operation, turn the machine off immediately,
disconnect 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
isolating the machine from the power supply by disconnecting the battery terminals.
