The suction motor does not start
The squeegee does not clean or
suction is ineffective
The batteries do not provide the
normal work time (battery models
only)
The battery discharges too fast
during use, even though it has
been charged correctly and when
tested with a hydrometer at the end
of recharging, it turned out to be
uniformly charged (battery models
only)
The battery discharges too fast
during use, recharging with an
electronic battery charger is too
fast and after recharging the bat-
tery supplies the right voltage
(about 2.14V for each element
without load), but when tested with
a hydrometer is found not to be
uniformly charged (battery models
only)
At the end of charging with the
electronic battery charger, the bat-
tery does not provide the correct
voltage (about 2.14 V per element
without load) and appears to be
uniformly not charged when tested
with a hydrometer (battery models
only)
the suction button LED is off
There is no power to the suction motor or the
motor is faulty
[B]= MOSFET temperature > 150°C
[B]= excessive motor absorption >30 A for 2
second
the edge of the rubber blades in contact with the
floor is worn
the squeegee or hose is blocked or damaged
the float switch has tripped (dirty water tank), is
clogged by dirt or broken
the suction hose is blocked
the suction hose is not connected to the squee-
gee or is damaged
there is no power to the suction motor or the
motor is faulty
the battery poles and charging terminals are
dirty and oxidised
the electrolyte level is low
the battery charger does not work or is unsu-
itable
there are considerable differences in density
between the various elements of the battery
the battery is new and does not deliver 100% of
its expected capacity
the machine is being used at maximum capacity
for continuous periods and the working time is
not sufficient
the electrolyte has evaporated and does not co-
ver the plates completely
the battery supplied filled with acid by the Ma-
nufacturer has been stored for too long before
being charged and used for the first time
The battery has not been connected to the
battery charger (for example, because the low
voltage connector of the battery charger has
been erroneously connected to the machine
connector)
the battery charger and power socket to which
the battery is connected are not compatible
the battery charger has not been installed cor-
rectly
the battery charger is not working
GB
press the suction button.
check that the motor power connector is
correctly connected to the main wiring; if
it is correctly connected, have the motor
replaced
[B]= stop the machine, leave to cool
down for 45'
[B]= stop the machine and check the
motor
replace the rubber blade
unblock and repair the damage
empty the dirty water tank or reset the
float switch
unblock the hose
connect or repair the hose
see: "The suction motor does not start"
clean and grease the poles and termi-
nals, charge the batteries
top up all the elements with distilled wa-
ter as described in the instructions
see battery charger instructions
replace the damaged battery
the battery must be "run-in" by perfor-
ming 20-30 charges and discharges to
obtain maximum performance
if possible, use batteries with a higher
capacity or replace the batteries with
others charged previously
top up all elements with distilled water
until the plates are covered then charge
the battery
if recharging with a normal battery char-
ger is not effective, you must use a dou-
ble recharging cycle:
- charge it slowly over a 10 hour period
at a current of 1/10 the nominal capacity
for 5 hours (e.g. for a 100Ah(5) battery
the current must be set at 10A, using a
manual battery charger);
- rest for one hour;
- charge it with the normal battery char-
ger.
connect the battery charger to the bat-
tery connector
check that the power supply characteri-
stics indicated on the battery charger ra-
ting plate comply with those of the mains
power supply
taking the actual voltage available at
the socket into account, make sure that
the connections of the primary of the
transformer inside the battery charger
are correct (consult the battery charger
manual)
make sure there is voltage to the batte-
ry charger, that the fuses are not blown
and that the current reaches the battery;
try charging with another rectifier. If the
battery charger is not working, contact
the technical service centre and indicate
the serial number of the battery charger
