Maintenance
Filter
The filter foam material in the optional filter should be replaced at regular intervals or if it is soiled.
O-rings
The O-rings for the filter, needles and test heads guarantee tightness and functioning of the system
and must therefore be replaced periodically.
Applying some silicone grease on the O-rings may prolong their service life and durability and may
increase system tightness.
CAUTION! Do not use mineral grease for the O-rings.
