to reach the spring.

once a year.
4
Remove the steam piston "C" behind the
spring "B".
We recommend replacing the piston at least
once a year.
The steam nozzle, in its simplicity, has compo-
nents that must be replaced due to wear.
It is recommended to replace:
• The piston seals (code No. 02280014) to
avoid misalignment.
• The seals of the lever block (02280011) and
the connection to the heater.
• The piston of inner closure (98008004).
RE-ASSEMBLY OF THE STEAM NOzzLE
During the reassembly phase it is important to
lubricate the seals of the piston in contact with
the lever, to ensure fluid movement inside the
housing.
