Maintenance
The model Sharon-Brush 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 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 (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. Check and periodically clean the filters of the vacuum motor, that are located in the transparent
cover of the recovery thank.
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 and of the brush
motor. This check should be done after 500 working hours. Consumed carbon brushed 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 personnel.
7. Periodically check that the brush rotates without problems, eliminating the causes which prevent a
free rotation. In case of difficulties, contact the technical assistance.
