You will need the following tools and consumables for maintaining the valve plungers:
– Lint-free cloths
– ISOFLEX TOPAS NCA 52 (Item no. 00328369-01, 00330850-01, 50 g tube)
– O-ring (Item no. 00345127-01)
– New valve plungers, if necessary (Item no. 00330711-02).
a Wipe the valve plungers with a dry lint-free cloth.
s Check the O-ring and the sealing lips of the valve plungers for damage and to ensure that they
are not seated too loosely.
: If the bottom four sealing lips are damaged or are seated too loosely, replace them with new
valve plungers.
d Grease the valve plungers extremely sparingly with a lint-free cloth moistened with ISOFLEX
TOPAS NCA 52.
There must be no visible grease residues.
Make sure that there is no grease in the groove.
