Push the rod for a few times and the cartridge body with some oil up to approx.20 mm
from the body top.
Screw the oil draining screw (1)in the compression valve unit (43)
Seal the cartridge end hermetically by screwing the compression valve (43)and make
the rod (25)perform a full stroke;after completing this operation,when the rod is
completely extended,you will see that the bladder tends to compress next to the 4
radial holes in the tube sleeve.
Insert the rod (25) slowly by about 50mm until the bladder is no longer compressed
next to the 4 holes.
Free the cartridge from the vice.
Fix the cartridge in the vice by means of the special protection jaws (R5198AC) so that
the 4 holes on the bladder are sealed; the jaws must be in contact with the upper cap,
as shown in the figure.
Unscrew the compression valve (43).
