Maintenance recommendations:
▪ Use the valve plunger ONLY when greased. (Isoflex topas).
▪ Replacing the valve plunger also means:
– Clean the valve plunger housing! Otherwise good plungers with new grease are installed in the
old, contaminated environment.
– Grease the valve plunger: Use the appropriate tool [03049689-01] to grease the valve plunger.
– Perform vacuum tests with the red SOKO nozzles, vacuum test DLM [03067029-01].
▪ Regularly check the sleeve-nozzle vacuum plate "blue" (available from 10/2008, white) and replace
when necessary (with 1.5mm Allen key).

▪ Set the air blast tube so that it overlaps the circular guide frame by 0.7 mm.
Scenario 2
Example of defective vacuum values, which indicate a
damaged silicone hose on segment 1 and an open nozzle
at segment 3.
NOTICE
Silicone hose defect
Under certain circumstances, silicone hose defects might only be detected when the segments
are moved out. It could therefore be advisable to release the Z axis and to perform a vacuum
test of the segment in its lowered state (single measurement run).
NOTICE
Missing valve plunger
If both measurements for a particular segment are only around 210mbar, this indicates that the
valve plunger is missing.
Vacuum values and valve plunger positions
▪ If the valve plunger is in the position "nozzle open",
the vacuum area will be sealed against the environ-
ment with two seals.
▪ If the valve plunger is in the position "nozzle closed",
the vacuum area (at the rear, near the drive) will be
sealed against the environment with only one seal.
If the "vacuum value closed" is too low, this indicates that
the seal is not sufficiently greased or that it is damaged.
