carefully following the manufacturer’s instructions,
is the best guarantee for obtaining the best perfor-
mances and extended machine service life.
For all scheduled maintenance operations, refer to the
instructions and warnings detailed in the paragraphs
below
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 odors.
7.2. SOLUTION FILTER CLEANING
Remove the transparent cap (PhotoE-36) then re-
move the metal strainer.
Clean them, reinstall the metal strainer in its seat and
close the water filter screwing the transparent cap.
7.3. SUCTION HOSE
Detach the suction hose from the squeegee (Photo
G-27) . Now you can wash the hose and remove any
obstructions.
Firmly insert the hose on the squeegee body.
7.4. 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 blades, follow the instructions in
the relative section. Turn the blades around to wear
down the other sharp corners or to install new ones.
7.4.1. SQUEEGEE DISASSEMBLY
Disconnect the suction hose from the coupling pipe on the
squeegee body ( Photo
G-27
).
Unscrew the two knobs ( Photo
G-45
) that secure the
squeegee to its support and push down the squeegee to
free it.
7.4.2. SQUEEGEE BLADES DISASSEMBLY /
ASSEMBLY
Disassemble the squeegee from its support ( see
7.5).
Unscrew the knobs ( Photo I-31) and remove metal
blade retainer ( Photo I-30)
Extract the fixing bolts ( Photo I-24) and remove
the front metal blade retainer ( Photo I-25 );
remove the squeegee rubber blades tearing them
from a side ( Photo I-26 ) ( Photo I-29 ).
To replace the squeegee rubber blades, follow the
same procedure on the contrary starting from the
front blade ( Photo I-26 );
lock the fixing bolts retaining them in the squared
seats in the squeegee body;
then, place the rear rubber blade ( Photo I-29)
and the metal blade retainer ( Photo I-30), locking
them with the fixing knobs ( Photo I-31 ).
7.5. ACCESSORIES
Remove and clean the brush or the abrasive pad disk.
• 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.
7.6. MACHINE BODY
Use a sponge or a soft cloth to clean the exterior of
the machine and, if necessary, a soft brush to elim-
inate 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. It is prohibited
to use steam machines, hoses with running water
and high-pressure cleaners.
7.7. BATTERIES
GEL batteries
Carry out maintenance operations in accordance with
the manufacturer’s instructions and with all the other
