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 (29) and clean it if necessary.
Unscrew the cup (28) and remove the filter (29).
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 (22) 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).
