ACTION
Each time used • Check the supply cable, high-pressure pipe, couplings, cleaner gun, lance
pipe.
Should any of these parts appear to be damaged, do not use the high
pressure cleaner and contact a Skilled Technician.
Weekly • Cleaning the water suction filter/gasket (33).
Usually, it is sufficient to pass the filter under running water or in a jet of
compressed air to clean it. In more difficult cases, use a lime scale remover
or replace the filter. Contact an authorised service centre for the purchase
of a new filter.
The inner water inlet filter must be cleaned by a Skilled Technician (see
also paragraph “Special maintenance”).
Monthly • Clean the nozzle (20).
For cleaning, it is generally enough to pass the supplied pin (19) inside
the nozzle hole. If you do not obtain suitable results, replace the nozzle by
applying to an authorised service centre to buy the spare part. To replace
it, use a 14-mm socket wrench (not supplied).
CAUTION
• During use, the high pressure cleaner should not be too noisy and large amounts of water or oil should
not drip from underneath it.
In this event, a Skilled Technician should test the appliance.
