INSTALLATION

K61 is pushed onto the piston rod on the clamping flange towards the rod and fixed by fastening. The nut has to be secured. The sliding surface and the cylinder bore should be oiled with oil that must not go into the reaction with the sealing element during the installation process.

NOTES

Before installation the sealing element must be oiled with system oil. Pay attention not to deform the sealing element during installation. Chamfer at the cylinder bore must be proper and free of burrs.
