• Clean the water inlet filter (35 or 14):
refer to what has been explained previously.
• Clean the detergent suction filter (29)

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 (24) 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.
CAUTION
• When working, the high pressure cleaner should not be too noisy and there should be no obvious drips
of water or oil underneath it. If this is the case have the machine checked by a
Specialized Technician
.
