6. On machines equipped with brush mo-
tor over-load protection device (see under
"OPTIONAL ACCESSORIES”), check
that on the display (1) does not appear
the alarm “AL01” (brush motor overload
alarm).
If the problem persists, please contact the
authorized technical assistance.
ATTENTION
:
Never leave the batteries discharged for a
long time.
THE MOTORS DO NOT FUNCTION
If the machine is supplied with the in-
corporated battery recharger (optional),
check:
1. if the recharging of the batteries is being
carried out. In this case the machine is not
connected.
2. that the switches are on.
3. that the general switch (12) is on or that
the key switch (see under "OPTIONAL
ACCESSORIES”) is in the correct posi-
tion (clockwise).
If the problem persists, please contact the
authorized technical assistance.
INSUFFICIENT WATER ON THE
BRUSH
1. Check that the solution valve lever (8)
is open.
2. Check the level of the liquid in the solu-
tion tank.
3. Check that solution filter (1) is clean.
4. If the machine is equipped with
solenoid valve (see under "OPTIONAL
ACCESSORIES”), act upon the brush
activation levers (7).
5. If the machine is equipped with the 3S
system (see under “3S SYSTEM SOLU-
TION SAVING SYSTEM”) (optional),
check that the switch of the detergent
solution supply is activated by choosing
between the traditional adjustment system
through the solution valve or the system of
fixed optimum supply. Furthermore, verify
that the filter of the auxiliary hydraulic
circuit is clean.
If the problem persists, please contact the
authorized technical assistance.
THE MACHINE DOES NOT CLEAN
PROPERLY
1. The brush does not have the suit-
able bristle dimension: use only original
brushes. For advice, contact the authorized
technical assistance.
2. The brush has worn bristles. Check
the brush wear condition and eventually
replace (the brush has to be replaced when
the bristles have reached a height of about
1/2” (15 mm)).
To replace the brush, see instructions at
paragraph “BRUSH DISASSEMBLY”
and “BRUSH ASSEMBLY”.
3. The solution detergent is insufficient:
open more the solution valve.
4. Check that the liquid detergent is in the
recommended percentage.
Contact the authorized technical assistance
for advice.
THE SQUEEGEE DOES NOT DRY
PERFECTLY
1. Check that the squeegee rubbers are
clean.
2. Check the height and inclination of the
squeegee (see under “SQUEEGEE” in
“BEFORE USE”).
3. Check that the suction hose is correctly
inserted in the proper seat on the recovery
tank.
4. Clean the suction filter.
5. Replace the rubbers if worn out.
6. Check that the suction motor switch is
on.
7. Check that the recovery tank is empty.
EXCESSIVE FOAM PRODUCTION
Check that low foam detergent has been
used. Eventually add small quantities of
anti foam liquid into the recovery tank.
Please be aware that a bigger quantity of
foam is produced when the floor is not
very dirty. In this case please dilute deter-
gent solution.
