product or replace the lter. To buy spares contact an authorised after-sales centre.
Fit the lter back on and screw the quick-t connection back on.
Monthly • Clean the nozzle.
Generally speaking, to clean the nozzle, it is enough to pass the pin (12) provided

authorised after-sales centre. The nozzle can be changed using a 14mm wrench (not
supplied).
