Pump the rod through its full stroke several times and top oil level up to about
20 mm below cartridge edge.
Tighten the bleed screw (1) into compression valve unit (43).
Seal cartridge end tightening the compression valve (43) and pump the rod (25)
through one complete stroke. When done, you will see the bladder collapse near
the 4 radial holes in the cartridge case.
Slowly push in the rod (25) by about 50 mm, until the bladder is no longer col-
lapsed at the four holes.
Remove the cartridge from the vice.
Clamp the cartridge in the vice in a vertical position using the suitable protector
(R5198AC) in such a manner as to block off the 4 holes in the bladder. The jaws
must contact the cap nut as shown in the gure.
Unscrew the compression valve (43).
