left to right. Cover backwards each stripe for a part corresponding to a little more than a half of the length.
Invert then the direction and clean the remaining part in the same way. Work more or less slowly
according to the dirtiness degree of the surface.
For a deep cleaning of carpet, some users suggest to spray the solution and leave it on the surfaces for
some minutes before sucking it. In this way the detergent has more time to act on the dirt. Each operator
will use his own method, also considering the type of carpet to clean.
The models Sabrina, Sabrina-Maxi, Serena-Silent and Grace are professional machines. The warranty on
these machines is of 1 year and covers the faults due to manufacturing defects. The faults due to
improper use are not covered by warranty. For further details regarding warranty, contact the distributor
supplying the machine.
Observe the following advice to obtain a perfect working and a long life of your machine:
1. After every use, before storing the machine, remove all the water from the solution and the recovery
tank. Put some liters of clean water into the solution tank and use the pump only, pressing the lever of
the solution valve. This operation is useful to clean the internal parts of the pump, of the couplings and
nozzles, removing the detergent residues.
2. After every use, store the machine in a cool and dry place with the cover open, to avoid that humidity
inside the recovery tank can condensate on the internal parts of the vacuum motor, therefore
damaging it. The damage provoked by humidity that condenses on the motor (or the foam sucked by
the motor) is not covered by warranty.
3. Periodically clean the water filter, extracting it from the machine and rinsing it under current water.
4. Periodically check and clean the filter of the vacuum motor, which is located between the 2 tanks for
the models Sabrina and Sabrina-Maxi, while for Serena-Silent and Grace is located under the
transparent circular cover of the upper tank.
5. Eliminate the lime that in time deposits inside the hydraulic circuit of the machine, by putting some
anti-lime solution in the solution tank and leave it for some hours. Then empty the tank and rinse. It is
enough to perform this operation every 6-8 months.
6. Periodically check the consume of the carbon brushes of the vacuum motor. This check should be
done after 500 working hours.
7. For Sabrina-Maxi, Serena-Silent and Grace, it is also necessary to check the carbon brushes of the
water pump, after 500 working hours.
8. Worn-out carbon brushes may result in damages to the vacuum motor or to the pump, which are not
covered by warranty. The check of carbon brushes should be done by technical personnel.
