ROUTINE MAINTENANCE

"STOP"
• Check the power cable, high-pressure hose, connections, spray gun and lance hose.
If any of these is damaged, do not use the high-pressure cleaner and contact a Skilled
Technician.
• Clean the water inlet filter (21).
Unscrew the quick-fit connection (23) and take out the filter (21). Generally speaking,
to clean this all that need be done is pass the filter under a jet of running water
or blow on it with compressed air. In the most difficult cases, use an anti-scale
product or replace the filter. To buy spares contact an authorised after-sales centre.
Fit the filter back on and screw the quick-fit connection back on.
• Clean the nozzle.
Generally speaking, to clean the nozzle, it is enough to pass the pin (12) provided
through the nozzle hole. If this is not successful, change the nozzle. Buy this from an
authorised after-sales centre. The nozzle can be changed using a 14 mm wrench (not
supplied).
• Clean the detergent suction filter (16)
Generally speaking, to clean the filter, all you need do is pass it under a jet of running
