ROUTINE MAINTENANCE

• Check the power cord, the high pressure hose, the connectors, the
cleaner gun and the lance pipe.
Should any of these look damaged, do not use the cleaner for any reason
and contact a Qualified Technician.
• Check the water inlet filter (18) and clean it if necessary.
Unscrew the hose support (25) and take the filter (18) out of the
connector (17).
Running water or compressed air is generally all that is needed to clean
the filter. In the most difficult cases, use a limescale remover or replace it,
contacting a Specialized Technician to buy the spare part.
Mount the filter again, following the above steps in reverse order.
• Clean the nozzle.
To clean the nozzle, it is generally sufficient to insert the pin (28) supplied
into the nozzle's hole. If no appreciable results are obtained, contact a
Qualified Technician to buy the spare part. The nozzle can be replaced
using a 14 mm/0.55" spanner (not supplied).
• Clean the detergent suction filter (46).
It is normally enough to put the filter under running water or blow it with
compressed air to clean it. In the more difficult cases use a water softener
or replace it, contacting a Specialized Technician to buy a new one.
• Cleaning the fuel fill up filter (47).
Unscrew the fuel tank cap (7) to reach the fill up filter. Take the filter out and
remove any impurities. In the more difficult cases replace it, contacting a
Specialized Technician to buy a new one.
