8 - MAINTENANCE
(
◊
) Turn the key, remove it from the control panel
and disconnect the battery from the machine
wiring.
(
☞
) 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 Vax service technicians.
Performing regular maintenance on the machine,
and carefully following the manufacturer’s
instructions, 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 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
machine is not being used) so that they can dry and
thus prevent the formation of foul odors.
8.2
SOLUTION FILTER CLEANING
Remove the transparent cap (Photo 29 - A) then
remove the metal strainer.
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 (Photo
23 - B). 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 (as determined by
appropriate risk assessment).
Detach the squeegee from the machine and clean
it under running water using a sponge or a soft
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 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
manufacturer: 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
eliminate 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*
PB-Acid batteries
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
immersed in the acid solution) will lead to rapid
oxidation and irreparably reduce the element’s
operating capacities.
An overflowing acid solution may corrode the ma-
chine.
Use battery chargers recommended by the
manufacturer 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
highly recommended.
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.
