Replace the pressure packings by applying a small amount of silicone grease to the
lips, being careful not to damage them when inserting the liner.
At each disassembly, the pressure packings must always be replaced together with all
the O-rings.

facing frontwards (toward the head).
Assemble the head ring (1, fig. 125), the high pressure packing (1, fig. 126) and the restop ring
(1, fig. 127).
