Cleaning and greasing
5.1
Cleaning
The seals are designed so that the lubricant film applied to them is effective for the entire service life of the seal. The ISO
cylinder must be cleaned thoroughly to remove all foreign particles, machining residues and old lubricants before it is
greased to ensure this life-time lubrication is retained.
All non-abrasive cleaning agents are permissible.
Note
Regular removal of the lubricant on the surface of the piston rod reduces its service life.
Note
• Clean with a soft, lint-free cloth and non-abrasive cleaning agents.
• Check the compatibility of the cleaning agent with the materials to be cleaned.
5.2
Greasing
The various components and seals of the ISO cylinder require different levels of greasing depending on a number of
factors.
Note
To ensure the life-time lubrication and so that a uniform lubricant film results:
• After greasing, move the piston rod with mounted piston and piston seals several times along the entire stroke of
the cylinder barrel.
5.2.1
Thin grease film
A film of grease covers the bearing surface so that a continuous film of grease exists and the grease colour darkens the
surface slightly.
Recommendation:
• Apply the grease with a paint brush, a fine bristle brush or similar.
5.2.2
Grease reservoir
Grease quantity enclosed between two sealing rings or in the enclosed ring volumes.

Maintenance and care
The ISO cylinders are maintenance-free, due to their life-time lubrication.
