Should any of these parts appear to be damaged, do not use the high
pressure cleaner and contact a Skilled Technician.
• Cleaning the water inlet filter
Remove the water inlet fitting (a) and remove the filter (b) with pliers (see Fig. 5).
Cleaning the filter under running water or a burst of compressed air is usually

Contact an authorised service centre to make sure you get the right spare part.
Replace the filter and secure the coupling fully.
• Clean the nozzle.
For cleaning, it is generally enough to pass the supplied pin (19) inside the
nozzle hole. In case you do not obtain any appreciable result, apply to an
authorised service centre.
