CHANGING THE NOZZLE
The high pressure nozzle fitted on the lance must be chan-
ged from time to time, as this component is subject to
normal wear during use. Wear may generally be detected
by a drop in the working pressure of the cleaner. To replace
it, consult your supplier and/or dealer for instructions.

These intervals refer to normal working conditions. For heavy duty use decrease the interval for each job.
For maintenance and/or repairs, use only original spare parts which offer the greatest characteristics of quality and
reliability. Failure to use original spare parts absolves the manufacturer from all liability and transfers it to the person
If the machine is to remain inactive for a long period, disconnect the supply sources, drain the tank(s) of all the operating fluids
and protect any parts that could be damaged by the accumulation of dust.
Grease the parts that could be damaged by drying out, such as the supply hoses. When bringing back into use, ensure that
there are no cracks or cuts in the water supply hoses.
Oil and chemical products must be disposed of according to current legislation.
If you no longer wish to use the water cleaner, you should render it unusable by removing the power cable.
You should also make sure that all potentially hazardous parts of the appliance are made safe, particularly for children who could
play with the unused water cleaner.
This product is classified as WEEE type special waste and is covered by the requisites of the new environmental protection
regulations. It must be disposed of separately from ordinary waste in compliance with current legislation and standards.
Do not use parts dismantled for scrap as spare parts.

DESCALING
Descaling must be carried out from time to time because the
scale present in the water partially deposits inside the hydraulic
circuit and the coil which with time becomes clogged.
Apply to our technical service centre to have the machine
descaled from time to time; this will save you money and
increase the efficiency of the cleaner.
