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 (at least every 2 months) 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.
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. 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.
