1.4 General safety instructions
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 specications 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 operating instruc-
tions for the device, as well as the documents listed in Chapter 1.1 on page 6.
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.
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 ofce offers the option of having the repair carried
out by Festo.
Due to the high torques, we recommend use of our repair service for cylinders with piston diameter 160 or larger.
Components and equipment replaced during repair must be disposed of in accordance with the relevant local environ-
mental protection regulations.
