• Clean the water inlet filter (18).
Unscrew the cap (28) with a 27 mm fixed jaw spanner and take the cartridge (27)
out, (see Fig. 6). It is normally enough to put the cartridge under running water
or blow it with compressed air to clean it. In the most difficult cases, use a scale
remover or replace it, contacting an authorised assistance centre to buy the new
cartridge.
Mount the cartridge and screw the plug back down.
• Clean the water inlet filter (18): refer to what has been explained previously.
• Clean the detergent suction filter (39) (S, TS).
It is normally enough to put the filter under running water or blow it with
compressed air to clean it. In the most difficult cases use a scale remover or replace
it, contacting an authorised assistance centre to buy the new filter.
• Clean the nozzle.
It is normally enough to put the pin (31) 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 nozzle can be replaced using a 14 mm box spanner (not supplied).
• Check soundness of the water inlet and outlet circuits.
• Check tyre inflation pressure.
• Check clamping of the pump to the engine and the engine to the frame.
If clamping is found to be insecure do not, under any circumstances, use the
high pressure cleaner and contact a Specialized Technician.
Turn the ring nut (52) anticlockwise until it is completely undone and take the filter
cartridge (27) out from the cup (51).
It is normally enough to put the cartridge under running water or blow it with
compressed air to clean it. In the most difficult cases, use a scale remover or replace
it, contacting an authorised assistance centre to buy the new cartridge.
Put the cartridge back in the cup (51) and close the filter, turning the ring nut (52)
