1 Important information
1.1 About these repair instructions
This document contains important
information about the professional
repair of the cylinder with piston rod
of the type ADN-…-KP and ADN-…-EL.
The cylinder with piston rod ADN-…-KP
and ADN-…-EL is fully repairable in the
event of damage due to normal wear.
The entire cylinder must be replaced
in the event of damage to the cylinder
barrel.
Before carrying out a repair, the
relevant chapter in these instructions
must be read in full and followed
consistently.
For reasons of clarity, these repair
instructions do not contain complete
detailed information. The following
documents should therefore also be
available when repairing the cylinder
with piston rod:
• Operating instructions for the
respective cylinder with piston
rod
Contains information about
the operating elements and
connections of the cylinder with
piston rod as well as the function,
structure, application, installation,
commissioning, maintenance and
care, etc. can be found on the
Festo website (www.Festo.com).
• Spare parts documentation
Contains an overview of the spare
and wearing parts as well as
information on their installation.
Can be found in the online spare
parts catalogue on the Festo
website (spareparts.festo.com).
• Assembly aids
Contains an overview of available
assembly aids such as lubricating
greases, locking agents,
maintenance tools, etc. (aids
for assembly and maintenance).
Can be found in the online spare
parts catalogue on the Festo
website (www.Festo.com).

1.3 General safety instructions
Warning
The cylinder with piston rod must only be repaired by authorised and trained persons in accordance with the
specications in the technical documentation and using original spare parts.
Installation and repair by unauthorised and untrained persons, repairs using non-original spare parts or without
the technical documentation required for installation and/or repair are dangerous and therefore not permitted.
Repairs must only be carried out in conjunction with these repair instructions and the device-specic operating
instructions.
Note
Instead of carrying out the repair yourself, your local Festo sales ofce offers the option of having the repair carried
out by Festo.
Environment
Components and equipment replaced as part of a repair must be disposed of in accordance with the locally valid
environmental protection regulations.
2 General product description
2.1 Functional description
The piston moves in the cylinder barrel when the cylinder chamber is pressurised. The piston rod transmits the movement
to the outside. The advanced piston rod is retracted again when the other cylinder chamber is pressurised.

4 Repair steps
4.1 Preparation
• Before starting the repair, remove any attachments (clamping device, end-position locking, etc.) in accordance with
the accompanying operating instructions.
• Keep your working environment tidy.
• Only use the spare parts and assembly aids (grease, locking agent, etc.) provided in the set of wearing parts.
Warning
Make sure that the bearing cap cannot suddenly come ying off.
• Remove the non-return valves and tubing connection from the cylinder and depressurise the cylinder completely
so that any pressure present is not suddenly released when the cylinder is opened.
To prevent damage to sealing rims or guide surfaces, do not use pointed or sharp-edged assembly aids.
4.2 Visual inspection
Check the cylinder for visible damage that might impair its function (e.g. warping of the piston rod) as well as deposits
and scoring. The entire cylinder must be replaced if the cylinder barrel is showing signs of signicant damage.

• ADN-20 to 63-…-KP
– Loosen the  ange screws in the bearing cap and and end cap and
remove them.
– Pull the bearing cap away from the piston rod.
– Remove the end cap from the cylinder barrel.
– Loosen the  ange screws in the cover with clamping unit KP and remove
them.
– Pull the cylinder barrel from the piston rod.
– Remove any residue of the screw locking agent from the threads of the
screws.
