1 Important information
1.1 About these repair instructions
This document contains important information about professional repair of the ISO cylinder of the type DSBC.
The ISO cylinder DSBC is fully repairable in the event of damage due to normal wear.
The entire ISO cylinder must be replaced in the event of damage to the cylinder barrel.
However, the costs of carrying out a repair must be considered in the case of larger defects.
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 all detailed information. The following documents should
therefore also be available while performing repair work on the ISO cylinder:
– Operating instructions
Contains information about the operating elements and connections of the ISO cylinder, as well as information
about its function, structure, application, installation, commissioning, maintenance and care, etc. This information is
available on the Festo website (www.festo.com/sp).
– Spare parts documentation
Contains an overview of the spare and wearing parts as well as information on their installation. This can be found in
the online spare parts catalogue on the Festo website (www.festo.com/spareparts).
– “Tools and repair accessories” information brochure
Contains an overview of the available installation resources, e.g. lubricating greases, threadlocking agents,
maintenance tools, etc. (resources for installation and maintenance). The brochure can be found in the online spare
parts catalogue on the Festo website (Tools and repair accessories.pdf).

• Activities that can be carried out in any order.
.1 Activities which should be carried out in the specied order.
Reference to further information
– General list
Underlined, blue text indicates a cross-reference or hyperlink that you can click on in the PDF.
1.4 General safety information
Caution
Risk of injury due to unintended switching on and unexpected movements.
• Ensure that the ISO cylinder is depressurised and protected against restarting before any repair or maintenance
work is carried out.
Caution
The ISO cylinder may only be repaired by authorised and trained persons in accordance with the specications in the
technical documentation and using genuine 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 respective device-specic
operating instructions.
Caution
Lifting large loads can lead to permanent injury.
• The ISO cylinder must be lifted by several people or with suitable lifting gear, depending on its size and weight.
Note
• Observe the given tightening torques. If no special information is given the tightening torques given in the relevant
standard apply to the screws, bolts and nuts used.
• Note the strength class of the screws, bolts and nuts!
Note
Carrying out repair work without the respective necessary technical documentation is dangerous, and therefore
not permissible. Repairs must only be carried out in conjunction with these repair instructions and the respective
operating instructions for the device, as well as the documents listed in Chapter 1.1 on page 6.
Festo recommends use of LOCTITE 243 threadlocker.
In the event of damage caused by unauthorised manipulation, improper use or use of non-original spare parts, all
warranty and liability claims against the manufacturer expire.

Instead of carrying out the repair yourself, your local Festo sales ofce offers the option of having the repair carried
out by Festo.
Components and equipment replaced during repair must be disposed of in accordance with the relevant local
environmental protection regulations.
1.5 Technical requirements
Note
The following instructions for safe and proper use must be observed:
– Observe the connection and ambient conditions specied in the technical data of the products and all the
connected components. The product can only be operated in compliance with the relevant safety guidelines if you
comply with the limit values and load limits (see enclosed documentation).
– The ISO cylinder must be in faultless technical condition.
– The ISO cylinder may only be operated in its original condition and without unauthorised modications.
– The ISO cylinder is designed for industrial use.
1.6 Standards and test values
Standards and test values which products comply with and full can be found in the "Technical data" sections of the
enclosed documentation.
