Necessary material and tools:
•
see
I
•
Hydraulic cylinder: JOUCOMATIC 43850028-0050
•
2 pieces of Polyamid PA6 tube 6 x 1 (outside dia. x wall thickness), approx. 0.5 m long
Instructions:
1.
Perform steps 1 and 2 of
I
.
2.
Remove the lines from the defective cylinder. To accomplish this press in the black securing
rings into the terminal nipples . Empty the cylinder into a container. Remove the terminal

3.
Screw the terminal nipples into the new cylinder and tighten firmly.
4.
Fill the new cylinder. To accomplish this fill a Polyamid PA6 tube 6 x1 approx. 0.5 m long
via a syringe with hydraulic fluid. Move the cylinder in
to
position 2
Connect the tube to the front terminal (rear cylinder) resp. the upper terminal (front cylinder).
Insert the other end of the tube into a container with hydraulic fluid and move the cylinder to
position 1.
5.
Fill the second Polyamid PA6 tube with hydraulic fluid and connect it to the other terminal
nipple of the cylinder. Insert also the other end of the tube into a container with hydraulic
fluid.
6.
Place the cylinder below the container and move the piston rod several times until no air
