5.
Check that the suction motor switch is on.
6.
Check the level in the recovery tank (see
under “OVERFILL PROTECTION”) and if
necessary, empty the tank.
7.
If the floor remains wet in the central part
of the drying, it is necessary to give more
pressure in the rear part of the squeegee,
screwing down of some turns the screw, as
shown in the picture.
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 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.
