Clean them, reinstall the metal strainer in its seat and
close the water filter screwing the transparent cap.
8.3 SUCTION HOSE
Detach the suction hose from the squeegee (Foto
H-27) . Now you can wash the hose and remove any
obstructions.
Firmly insert the hose on the squeegee body.
8.4 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.
8.5 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.
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 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.
8.7 BATTERIES
GEL batteries
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.
8.8 PERIODIC MAINTENANCE
For all the operations described in the following
scheduled maintenance table, refer to the instruc-
tions and detailed warnings in the relative sections.
8.9 RECOMMENDED SPARE PARTS
You’ll always be able to use your machine as efficien-
tly as possible by maintaining a stock of the most
common consumable materials and by scheduling
routine and extraordinary maintenance. Contact your
dealer for a list of these spare parts.
