6.14 WORK METHOD
6.14.1 PREPARATION AND WARNINGS
Remove any loose solid residue from the surface
to be treated (using suitable tools, such as vacuum
cleaners, sweepers, etc.). It this is not done, the
solid dirt might prevent the squeegee from opera-
ting correctly, reducing drying efficiency.
Only trained personnel can drive this machine.
6.14.2 BATTERY CHARGE LEVEL CON-
TROLS
The sequence of lights of the battery charge con-
trol ( Photo C - 3, E - 1 ) progressively turns off
until the battery is discharged . When the red light
turns on ( Photo C - 3C, E - 1C ), turn off the brush
motor, close the detergent solution outlet, finish
drying the small residual moisture and go to the
battery charging area to charge the battery.
( ! ) The batteries may be irreparably damaged if
the residual charge level drops too low (see the
battery operating manual). Do not force the battery
discharge beyond the safety limits, turning the key
off and on or in any other manner.
6.14.3 DIRECT SCRUBBING OR FOR
SLIGHTLY DIRTY SURFACES
Scrubbing and drying in a single pass.
Prepare the machine as previously described and
use it as described in paragraph 6.13.
☞
Never use the machine without the detergent
solution: the floor might be damaged.
6.14.4 INDIRECT SCRUBBING OR FOR
VERY DIRTY SURFACES
Scrubbing and drying in various passes.
Prepare the machine as previously described.
First set of operations:
Wash the floor as described in paragraph 6.13, wi-
thout drying the floor
Allow the detergent solution to work on the dirty
floor according to what is indicated in the informa-
tion relative to the detergent used.
Second set of operations:
Proceed as explained in the previous “Direct Wa-
shing” paragraph (6.14.3) to also proceed with
drying the floor.
•
Never use the machine without the detergent
solution: the floor might be damaged.
6.14.5 POST-SCRUBBING OPERATIONS
Close the detergent solution outlet.
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;
empty and clean the tanks (as described in 6.11).
Turn off the machine using the key and remove it
from the control panel.
If necessary, charge the battery (see the relative
section).
7. MAINTENANCE INFORMATION
•
Turn the key, remove it from the control panel
and disconnect the battery from the machine wi-
ring.
☞
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 authorized service
centers or by specialized 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
sections.
Remove any solid dirt by filling and draining the
tanks until all dirt has been eliminated: use a wa-
shing hose or similar tool to do this.
( ! ) Water hotter than 50°, a high-pressure clea-
ner or excessively powerful sprays may damage the
tanks and the machine.
Leave the plugs of the tanks open (only while the
machine is not being used) so that they can dry
and thus prevent the formation of foul odors.
7.2 SUCTION HOSE
Detach the suction hose from the squeegee ( Photo
M - 3).
Now you can wash the hose and remove any ob-
structions.
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 constan-
tly 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 blades, follow the instructions
in the relative section. Turn the blades around to
wear down the other sharp corners or to install
