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.
Now you can wash the hose and remove any ob-
structions.
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 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 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 bru-
shes or on the abrasive disks). If necessary, adjust
the slant of the action on the floor.
Use only the accessories recommended by the ma-
nufacturer: other products may reduce operating
safety.

8.5 MACHINE BODY

Use a sponge or a soft cloth to clean the exterior of
the machine and, if necessary, a soft brush to eli-
minate tough dirt. The machine's shockproof sur-
face 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 machines can be used but it's prohibited to
use hoses with running water or a high-pressure
cleaner.

8.6 BATTERIES

8.6.1 PB-ACID

Carry out maintenance operations in accordance with
the manufacturer's instructions and with all the other
instructions provided in this manual.
Exposing the element plates (not completely immer-
sed in the acid solution) will lead to rapid oxidation and
irreparably reduce the element's operating capacities.
An overflowing acid solution may corrode the machine.
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 explosion risk!
The use of gel or maintenance-free batteries is hi-
ghly recommended.

8.6.2 GEL

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.

8.7 FUSES AND THERMAL BREAKERS

The machine is equipped with electric protection
devices on the main operating components to avoid
costly malfunctions.
Thermal cutouts are installed to protect the drive
motor wherever foreseen and the brush motor.
When one of these breakers trips automatically, the
disabled function can be reactivated by fully de-
pressing the breaker that tripped.
When the thermal breakers trip, especially when
the machine is used during the first few weeks, it
might not be caused by actual machine malfun-
ctions. However, a specialised technician should
check the device if the relative breaker continues
to trip.

8.8 PERIODIC MAINTENANCE

For all the operations described herein, refer to the
instructions and detailed warnings in the relative
sections.
