• Clean the water inlet filter (45).
Unscrew the cap (51) with a 27 mm fixed jaw spanner and take the cartridge out (50),
(see Fig. 7). 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 (23).
Turn the ring nut (62) anticlockwise until it is completely undone; take the filter
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 filter, turning the ring nut (62)
clockwise.
• Clean the water inlet filter (45) or (23) (refer to what has been explained previously)
(only for FDX-PRO, FDX4 and FDX Xtreme).
• Clean the detergent suction filter (40) (not for FDX2 10/150 and FDX Xtreme).
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 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 fixed fan nozzle mounted on the nozzle holder heads (24) and (25)
and spray gun (57) can be replaced using a 14 mm box spanner (not supplied). To
replace the nozzle of head (48) contact an authorised assistance centre.
• Oil or grease the rotating or sliding parts the operator is able to reach (refer also to
the engine operating and maintenance manual).
• 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.
