The squeegee does not
clean or has poor suction
The batteries do not pro-
vide the normal work time
(battery models only)
The battery discharg-
es too fast during use,
even though it has been
charged correctly and
when tested with a hy-
drometer at the end of
recharging, it turned out
to be uniformly charged
(battery models only)
The battery discharges
too fast during use, re-
charging with an electron-
ic battery charger is too
fast and after recharging
the battery 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 battery 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
model only)
The edge of the rubber blades in contact with
the squeegee or hose is blocked or damaged
is clogged by dirt or broken
the suction hose is blocked
The suction hose is not connected to the
squeegee 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 unsuit-
able
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 capac-
ity for continuous periods and the working time
the electrolyte has evaporated and does not
cover the plates completely
ufacturer has been stored for too long before
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
replace the rubber blade
unblock and repair the damage
unblock the hose
connect or repair the hose
see: "The suction motor does not start"
clean and grease the poles and terminals, re-
charge the batteries
top up all the elements with distilled water as de-
scribed in the instructions
see battery charger instructions
replace the damaged battery
the battery must be "run-in" by performing 20-30
charges and discharges to obtain maximum per-
formance
if possible, use batteries with a higher capacity
or replace the batteries with others charged pre-
viously
top up all elements with distilled water until the
plates are covered then recharge the battery
- if recharging with a normal battery charger is not
- charge 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,
- charge with the normal battery charger.
connect the battery charger to the battery con-
nector
check that the power supply characteristics indi-
cated on the battery charger rating 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 battery charger,
that the fuses are not blown and that the current

number of the battery charger
