THE BRUSH MOTOR DOES NOT WORK
1. Check the charge level of the batteries that is
visible when switching on the general switch (1) (see
under “BATTERIES CHARGE LEVEL INDICATOR”).
2. Verify that the brush motor switch (2) is activat-
ed checking that its signal lamp is on.
3. Activate the scrub control levers (3).
If the problem persists, please contact the authorized
technical assistance.
INSUFFICIENT WATER ON THE BRUSH
1. Check that the solenoid valve switch (1) is acti-
vated verifying that the signal lamp is on.
2. Check the level of the liquid in the solution tank
(see under “DETERGENT SOLUTION TANK”).
3. Check that the solution flow adjusting knob (2) is
sufficiently open.
4. Press the brush control levers (3).
If the problem persists, please contact the authorized
technical assistance.
THE MACHINE DOES NOT CLEAN PROPERLY
1. The brush does not have the suitable bristle di-
mension: use only original brushes. For advice, con-
tact the authorized technical assistance.
2. The brush has got worn bristles. Check the brush
wear condition and eventually replace it (the brush
has to be replaced when the bristles have reached a
height of about 15mm).
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 recom-
mended percentage.
Contact the authorized technical assistance for ad-
vice.
THE MACHINE TENDS TO MOVE SIDEWAYS
Acting upon the adjustment nut (A) placed on the
brush base group, it is possible to correct the direc-
tion of the machine movement. Screw down the nut
to correct the direction to the left, and unscrew it to
increase the direction to the right.
THE SQUEEGEE DOES NOT DRY PERFECTLY
1. Check that the squeegee rubbers are clean.
2. Check the height and inclination of the squeegee
(see section “SQUEEGEE ASSEMBLY” 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. Even-
tually 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 detergent solution.
LED (2), (3) AND (4) BECOME RED
If the machine is in the driving sense, with the gen-
eral switch (1) on and one of the three led (2), (3) or
(4) change colour, from green to red, it means that,
an amperemetric protection is taking place, for ex-
ample:
- LED (2) RED: the brush motor is having too big
stress.
- LED (3) RED: the suction motor is aspirating water
and therefore is forcing too much.
- LED (4) RED: the coil of the solenoid valve may be
short-circuited.
To reset, switch off the general switch (1), wait a few
minutes and then switch on again.
If the problem persists, please contact the authorized
technical assistance.
