Attention!
Before carrying out the following operations, wear gloves with a minimum cut protection of 3 in
accordance with EN388.

Disassemble the upper and lower rinsing arms.

Clean all nozzles, removing any obstruction found, and reassemble them.

Disassemble the curtains and clean them with a nylon brush under running water.

Disassemble the upper and lower washing arms and rinse them.

Remove the washing pump filter and rinse it.

Clean the washing tank thoroughly.

Due to the calcium and magnesium salts present in the water, after a certain period of operation,
which varies according to the hardness of the water used, a calcareous layer deposits in the inner
surfaces of the boiler tank and of the pipes, compromising the proper functioning of the machine.

It is therefore necessary to periodically remove incrustations, an operation that should be carried out
by technically qualified personnel.

If the machine is to be left unused for a long period of time, the steel surfaces must be greased with
Vaseline oil.

If there is danger of water freezing, have technically qualified personnel drain the boiler water and
the washing pump water.

If intense calcareous deposits form inside the machine in the presence of water, use an incrustation
removing product.

To remove the incrustations, carefully follow the instructions of the manufacturer of the product, or
seek the assistance of qualified personnel. In any case, always rinse the machine thoroughly after
removing incrustations.

Make sure the safety devices are working efficiently.

If the steam condensing battery is dirty, disassemble it and clean the spaces between the flaps using
compressed air.

REMINDERS:
Every mechanical and electromechanical part of the machine is subject to physical wear. A qualified
technician must carry out periodical inspections on:
- Conveying system sledges
- Washing/rinsing electro-pump seals
- Door guides and springs
- Remote control switch
- Safety devices
In addition, it is obligatory to test and inspect the devices that are not part of the machine, such as
earthing differential, proper earthing, automatic switches and/or fuses in the power line, every electric
conductor, the status of water pipes, discharge system, proper functioning of dispensers.

In case of malfunctioning, seek only technical assistance centres authorised by the
manufacturer or by the manufacturer's dealer.
