19. Apply anti-seize to the head outer surface, especially static o-ring (7).
20. Coat the entire rod assembly with hydraulic fluid and insert the rod into the cyl-
inder tube. When inserting cylinder head (5), make sure that static o-ring (7)
does not extrude into the retaining ring slot in the cylinder tube. Be careful not to
nick the seals as they enter the cylinder tube.
21. Rotate the cylinder head until the retaining ring hole is visible through the slot
milled into the tube. Insert retaining ring (14) hook into the hole and rotate the
head 1-1/4 turns until the retaining ring is completely pulled into the cylinder
tube and the ends are covered.
22. Reinstall the hydraulic cylinder into the unit and reconnect the hydraulic hose.
Refill hydraulic fluid reservoir.
23. Pressurize the cylinder and extend one full stroke to fill it with hydraulic fluid
and remove any trapped air.
