is the best guarantee for obtaining the best perfor-
mances 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 covers of the tanks open (only while the
machine 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.
Pull out the suction hose from its connection hole
placed in the recovery tank.
Now you can wash the hose and remove any obstruc-
tions.
After the cleaning, firmly insert again the suction hose
inside connection hole placed in the recovery tank.
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 con-
tact 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 efficiently. This is why the
squeegee strips must be replaced.
To replace the worn straps, follow the instructions in
the relative section. Turn the straps 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,
carefully check if foreign matter, such as metallic
parts, screws, chips, cords or similar items, has be-
come 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.
CLEANING SOLUTION FILTER
Make sure that the detergent solution tank is empty.
Check and clean the solution filter located in the
lower front part of the machine. Clean with running
water if necessary and check that the detergent solu-
tion is being delivered on the brushes.
Fully tighten the filter to prevent leaks during operation.
7.6.
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.
7.7.
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 ir-
reparably 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.
7.8.
FUSES AND THERMAL BREAKERS
The machine is equipped with electric protection
devices on the main operating components to avoid
costly malfunctions.
When one of these breakers trips automatically, the
disabled function can be reactivated by fully de-
