Second set of operations:
Follow the steps described in the previous section
“Direct Scrubbing” (7.8.3).
To avoid damage to the surfaces being treated,
the brush motor will stop automatically about 2
sec- onds after the advancement pedal has been
com- pletely released.
When moving in reverse, the squeegee will lift and
suction will be deactivated automatically. After
changing direction (forward direction), the squee-
gee and the suction will automatically return to
their previous condition.
•
Never use the machine without the detergent
solution: the floor might be damaged
7.7.5 POST-SCRUBBING OPERATIONS
Cut off the supply of detergent.
Lift the brush unit and turn off the brush motor.
After having completely dried any traces of water
on the surface, wait a few seconds and then lift the
squeegee and turn off the suction motor.
Move to a suitable location to drain the tanks (as
described in 7.4 and 7.5).
Empty and clean the tanks (see sections 7.4 and
7.5).
Turn off the machine using the key and remove it
from the control panel.
If necessary, charge the battery (see the relative
section).
8. MAINTENANCE INFORMATION
•
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 explicitly described in this manual)
should be carried out only by authorised service
centres or by specialised 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.
8.1 TANKS
Drain the two tanks as described in the relative
sections. Remove any solid dirt by filling and drain-
ing 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.
8.2 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 ob-
structions.
After the cleaning, firmly insert again the suction
hose inside connection hole placed in the recov-
ery tank.
Firmly insert the hose on the squeegee body.
8.3 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 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, fol-
low 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 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 manufacturer: other products may reduce op-
erating safety.
8.5 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 de-
tergent 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 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 ma-
