STeaM nOzzle
The steam nozzle is composed of a piston actu-
ated by the knob, which presses on a nut with
spring return. By pressing against the spring it
creates space for the steam to pass.
We suggest to replace the seals that keep the
piston perfectly aligned, every 4-6 months. Every
year it is advisable to replace the nut to prevent
the gasket that insulates the steam from drying
and letting seam pass. Since these parts must
be changed, we suggest replacing all the seals
simultaneously.
