tomatically in order to avoid to damage itself. After
changing direction (forward direction), the squee-
gee will automatically return to their previous con-
dition.
8. MAINT ENANCE INFORMAT ION
Turn the key, remove it from the control panel
and disconnect the battery from the machine wir-
ing.
All work on the electrical system as well as all
maintenance and repair operations (especially
those not ex plicitly described in this manual)
should be carried out only by authorised service
centres or by specialised technical personnel who
are ex perts 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 ex tended machine service life.
8.1
T ANKS
Drain the two tanks as described in the relative
sections.
Remove any solid dirt by filling and draining the
tanks until all dirt has been eliminated: use a wash-
ing hose or similar tool to do this.
Water hotter than 50° , a high-pressure
cleaner or excessiv ely powerful spray s may
damage the tank s 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.
8.2
SUCT ION 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 ob-
structions.
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.
8.3
SQ UEEGEE
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 con-
stantly in this manner tends to round or to dete-
riorate 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.
8.4
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
become j ammed.
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, ad-
j ust the slant of the action on the floor.
Use only the accessories recommended by the
manufacturer: other products may reduce operat-
ing safety.
8.5
CLEANING SOLUT ION FILT ER
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
solution is being delivered on the brushes.
Fully tighten the filter to prevent leaks during op-
eration.
8.6
MACHINE BODY
Use a sponge or a soft cloth to clean the ex terior 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 ma-
chines can be used but it's prohibited to use hoses
with running water or a high-pressure cleaner.
8.7
BAT T ERIES
8.7.1
PB-ACID
Carry out maintenance operations in accordance
with the manufacturer's instructions and with all
the other instructions provided in this manual.
Ex posing the element plates (not completely im-
mersed in the acid solution) will lead to rapid ox ida-
tion and irreparably reduce the element's operating
capacities.
An overflowing acid solution may corrode the ma-
chine.
Use battery chargers recommended by the manu-
facturer 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 ex plosion risk!
The use of gel or maintenance-free batteries is
highly recommended.
