SERVICE MANUAL
SAFETY
The following symbols indicate potentially dangerous situations. Always read this information carefully and take the necessary precautions to protect people and objects.
DANGER!
It indicates a dangerous situation (risk of death) for the User.
WARNING!
It indicates the risk for people of being injured and for objects of being damaged.
CAUTION!
It indicates a caution or a remark related to important or useful functions. Pay particular attention to the paragraphs marked by this symbol.
GENERAL SAFETY RULES
The following specific warnings and cautions inform you of any potential danger of damaging people or machines.
DANGER!
– Position the machine on a level ground; before performing any maintenance/repair procedures,
turn the machine ignition key to OFF position and disconnect the battery through the special
connector. – This machine must be used by fully trained and authorized personnel only. – Keep sparks, flames and other sources of ignition away from the battery. During the normal
operation explosive gases are released. – Do not wear jewels when working near electrical components. – Do not work under the lifted machine, if it is not securely fixed. – Do not operate the machine near toxic, dangerous, inflammable and/or explosive powders,
liquids or vapors. – Battery charging produces highly explosive hydrogen gas. Keep the tank assembly open during
battery charging and perform this procedure only in well-ventilated areas and away from naked
flames.

SERVICE MANUAL
WARNING!
– Carefully read all maintenance/repair instructions before performing any maintenance/repair
procedure.
– Before using the battery charger, ensure that frequency and voltage values, indicated in the
machine serial number plate, match the mains voltage.
– Take all necessary precautions to prevent hair, jewels and loose clothes from being caught by the
machine moving and vacuuming parts. – Do not smoke during battery charging. – Before leaving the machine unattended, make sure that the machine cannot move and remove the
ignition key. – Do not use the machine on surfaces with a gradient greater than the one indicated on the
machine. – Do not wash the machine with direct or pressurized water jets, or with corrosive substances. – Do not use the machine in particularly dusty areas. – While using this machine, take care not to cause damage to other people. – The storage temperature must be between +32°F and +104°F (0°C and +40°C). – The machine operating temperature must be between +32°F and 104°F (0°C and +40°C). – Humidity must be between 30% and 95%. – Always protect the machine from the sun, rain and bad weather, when it is both in the operating
and stationary state. – Do not use the machine as a means of transport. – Do not use the machine on ramps or slopes with an inclination higher than 2%. – Do not allow the broom to operate while the machine is stationary to avoid damaging the floor. – In case of fire, possibly use a powder fire extinguisher, not a water fire extinguisher. – Do not bump into shelves or scaffoldings, particularly where there is a risk of falling objects. – Do not remove or modify the plates affixed to the machine. – If parts must be replaced, contact an Authorized Dealer or Retailer for ORIGINAL spare parts. – The machine must be disposed of properly, because of the presence of toxic-harmful materials
(batteries, etc.), which are subject to standards that require disposal in special centers (see
chapter “Scrapping”). – Do not let any object enter the openings. Do not use the machine in case the openings are
clogged; always keep the openings free from dust, hairs and any other foreign material which
could reduce the air flow. – This machine cannot be used on public roads or streets. – Pay attention during the machine transfers when temperature is below the freezing point. The
water in the recycling tank or in the pipes could freeze and seriously damage the machine. – Only use the brooms and pads/cylindrical brooms supplied with the machine and those specified
in the Instructions for Use Manuals. Using other brooms or pads/cylindrical brooms could reduce
safety.
