• Turn the key, remove it from the control panel and
disconnect the battery from the machine wiring.
☞ All work on the electrical system as well as all main-
tenance and repair operations (especially those not
explicitly described in this manual) should be carried
out only by authorised service centres or by speciali-
sed technical personnel who are experts in the sector
and in the pertinent safety regulations.
Performing regular maintenance on the machine,
and carefully following the manufacturer's instruc-
tions, is the best guarantee for obtaining the best
performances and extended machine service life.
7.1. TANKS
Drain the two tanks as described in the relative sec-
tions.
Remove any solid dirt by filling and draining the
tanks until all dirt has been eliminated: use a washing
hose or similar tool to do this.
• Water hotter than 50°, a high-pressure cleaner
or excessively powerful sprays may damage the
tanks and the machine.
Leave the plugs of the tanks open (only while the ma-
chine is not being used) so that they can dry and thus
prevent the formation of foul odours.
7.2. SUCTION HOSE
Detach the suction hose from the squeegee.
Now you can wash the hose and remove any obstruc-
tions.
Firmly insert the hose on the squeegee body.
7.3. SQUEEGEE
• Do not handle the squeegee with bare hands:
wear gloves and any safety clothing needed to carry
out the operation.
Detach the squeegee from the machine and clean it
under running water using a sponge or a brush.
Check the efficiency and the wear on the strips in
contact with the floor. They are designed to scrape
the film of detergent and water on the floor and to
isolate that portion of the surface to enhance the
vacuum of the suction motor: this ensures that the
machine will dry very efficiently. Working constantly
in this manner tends to round or to deteriorate the
sharp edge of the strip, thus reducing drying efficien-
tly. This is why the squeegee strips must be replaced.
To replace the worn blades, follow the instructions in
the relative section. Turn the blades around to wear
down the other sharp corners or to install new ones.
7.4. ACCESSORIES
Remove and clean the brushes or the scraper disks.
• To avoid damaging the floor and the machine, careful-
ly check if foreign matter, such as metallic parts, screws,
chips, cords or similar items, has become jammed.
Check that the brushes are flat as they work on the
surface (check for any irregular wear on the brushes
or on the abrasive disks). If necessary, adjust the slant
of the action on the floor.
Use only the accessories recommended by the manu-
facturer: other products may reduce operating safety.
7.5. MACHINE BODY
Use a sponge or a soft cloth to clean the exterior of
the machine and, if necessary, a soft brush to elimi-
nate tough dirt. The machine's shockproof surface
is rough to make it harder to see scratches caused
during use. However, this does not make it easier to
remove tough stains on the surface. Steam machines
can be used but it's prohibited to use hoses with run-
ning water or a high-pressure cleaner.
7.6. BATTERIES
PB-ACID
Carry out maintenance operations in accordance with
the manufacturer's instructions and with all the other
instructions provided in this manual.
Exposing the element plates (not completely immersed
in the acid solution) will lead to rapid oxidation and irre-
parably reduce the element's operating capacities.
An overflowing acid solution may corrode the machine.
Use battery chargers recommended by the manufac-
turer and, in any case, those that are suitable for the
type of battery to be charged.
Always charge batteries in well-ventilated rooms:
there is an explosion risk!
The use of gel or maintenance-free batteries is highly
recommended.
GEL
Carry out maintenance operations in accordance
with the manufacturer's instructions and with all the
other instructions provided in this manual.
Use only those battery chargers recommended by
the manufacturer.
☞ If the batteries are not used, in either case, for an
extended period of time, disconnect them and re-
store the charge within the time limits specified for
the type of battery used (generally and as a precau-
tion, no more than 3 months for Pb-acid/GEL/AGM
batteries, 6 months for Li-ion batteries).
The manufacturer accepts no liability for damage to
batteries caused by failure to follow this procedure.
7.7. FUSES AND THERMAL BREAKERS
The machine is equipped with electric protection
devices on the main operating components to avoid
costly malfunctions.
Thermal cutouts are installed to protect the drive mo-
tor wherever foreseen and the brush motor.
When one of these breakers trips automatically, the
disabled function can be reactivated by fully depres-
