THE MACHINE DOES NOT CLEAN PROPERLY
1.
The brush does not have the suitable bristle
dimension: use only original brushes. For
advice, contact the authorized technical
assistance.
2.
The detergent solution is insufficient: open
the solution flow adjuster (3).
3.
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 that the coupling of the suction hose
is correctly inserted in the proper seat on
the recovery tank and on the squeegee bar.
3.
Check the suction filter and clean it.
4.
Replace the rubbers if worn.
5.
Check that the suction motor switch is on.
Check the level in the recovery tank (see under
“OVERFILL PROTECTION”) and if necessary, empty
the tank.
EXCESSIVE FOAM PRODUCTION
Check that low foam detergent has been used.
Add small quantities of anti foam liquid into the
recovery tank.
Do not use excessive amounts of detergent as
even with low foaming agent, the foam will be
created and lead to vacuum motor damage. Also
excessive detergent will result in solution pipe
blockages over time.
Please be aware that a larger 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
general switch (1) on green 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 example:
-
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.
