– 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.
Replace the sleeves and the valve plungers

as follows:

changer.
a Open the protective cover.
Do not hold the sleeves with your bare hands. Always wear laboratory gloves when carrying out
maintenance work on the sleeve. In this way you will avoid dirtying the glass disk and the
12
friction wheel unnecessarily, which could cause malfunctions (counting errors and overswing).
s Remove the sleeves from the head.
Pull out the sleeves as shown in the diagram.
12
d Put them into the containers provided.
