• the float switch has tripped (dirty
water drum), is clogged by dirt or
broken
• empty the dirty water drum
or reset the float switch
• the suction hose is blocked • unblock the hose
• the suction hose is not
connected to the squeegee or is
damaged
• connect or repair the hose
• there is no power to the suction
motor or the motor is faulty
• check that the motor power
connector is correctly
connected to the main wiring
and that the fuse is not
blown; in the second case
have the motor replaced
The machine does not move
• the suction motor does not
operate
• release the emergency
button; make sure the motor
is connected correctly to the
main wiring; check the type of
alarm present on the board
(see chapter 10); replace the
motor.
• the motor thermal cutout has
tripped; the motor has
overheated
• stop the machine, turn it off
and leave it to cool for at
least 45’
• the batteries are flat • recharge the batteries
The batteries do not provide
the normal work time
• the battery poles and charging
terminals are dirty and oxidised
• clean and grease the poles
and terminals, recharge the
batteries
• the electrolyte level is low • top up all the elements with
distilled water as described in
the instructions
• the battery charger does not
work or is unsuitable
• see battery charger
instructions
• there are considerable
differences in density between
the various elements of the
battery
• replace the damaged battery
• you are using the machine with
excessive pressure on the
brushes
• reduce pressure on the
brush
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
• the battery is new and does not
deliver 100% of its expected
capacity
• the battery must be "run-in"
by performing 20-30 charges
and discharges to obtain
maximum performance
• the machine is being used at
maximum capacity for
continuous periods and the
working time is not sufficient
• if possible, use batteries with
a higher capacity or replace
the batteries with others
charged previously
• the electrolyte has evaporated
and does not cover the plates
completely
• top up all elements with
distilled water until the plates
are covered then recharge
the battery
