– Laboratory gloves
– Lint-free cloths
– Lens cleaning cloth (e.g. Kodak)
– Lint-free cottonwool buds
– SIPLACE cleaning cloth (Item no. 00315253-01)
– Ethyl alcohol
– Set of cleaned sleeves
– Set of cleaned and slightly greased valve plungers.

The sleeves may be replaced at the same time as the cleaned ceramic nozzles. The procedure is
as follows:

changer.
a Open the protective cover.

s Remove the sleeves from the head.
Pull out the sleeves as shown in the diagram.
