Maintenance
AVB9X is a professional machine. The warranty on these machine is of 1 year and regards 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.
For a good preservation and a long duration of the machine, observe the following advice:
1. After each 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 prevent humidity
inside the recovery tank from condensing on the internal parts of the vacuum motor, therefore
damaging it. The damage provoked by humidity that condenses on the motor (like the damage
caused by 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. 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.
5. Periodically check and clean the filter of the vacuum motor, which is located under the transparent
circular cover of the upper tank.
6. Periodically check the consume of the carbon brushes of the vacuum motor. This check should be
done after 500 working hours.
7. Periodically check also the carbon brushes of the water pump, after 500 working hours.
8. Check the consume of the carbon brushes of the brush motor, after 1500 working hours.
9. Worn-out carbon brushes may result in a damage to vacuum motor or pump, which are not covered
by warranty. The check of carbon brushes should be done by technical assistance.
10. Periodically check that the brush rotates without problems, eliminating the causes which prevent a
free rotation. In case of difficulties, contact the technical assistance.
