• Clean the water inlet lter(23).
Turn the ring nut(62) anticlockwise until it is completely undone; take the lter
cartridge (63) out and clean it as explained above; in the case of truly stubborn dirt
change the cartridge, contacting a Specialized Technician for the right cartridge
to use; put the cartridge back in place and close the lter, turning the ring nut (62)
clockwise.
Monthly • Clean the water inlet lter(45) - (23) - (39) (refer to what has been explained
previously).
• Clean the detergent suction lter(40).
It is normally enough to put the filter under running water or blow it with
compressed air to clean it. In the most dicult cases use a scale remover or replace
it, contacting an authorised assistance centre to buy the new lter.
• Clean the nozzle.
It is normally enough to put the needle (29) supplied through the hole of the
nozzle to clean it. If the results are not good, replace the nozzle purchasing it from
an authorised assistance centre.
The professional xed fan nozzle mounted on the nozzle holder heads (24) and
spray gun(19) can be replaced using a 14 mm box spanner (not supplied).

the engine operating and maintenance manual).

drips of water or oil underneath it. If this is the case have the machine checked by a Specialized
Technician.
