paragraph "Informative letter").
4.2 ZTF system filling and purging
The ZTF system is already supplied oil-filled and purged, ready to be used. Therefore, no periodical oil topping
up is required.
The following filling and purging procedure must be carried out only after having repaired a fault, e.g. in case of
hose breaking or replacement of the cylinder gaskets. This kind of events entails oil leakage from the system
and, consequently, refilling is required.
Fault situations must be examined on case-by-case basis.
The purging procedure of the ZTF system requires the use of Ultraflex Bubble Buster, which is not provided in
this kit.
