Conditions of use for “electronic documentation”

I.  Protection rights and scope 

of use

The file of your choice is subject to protection 

provisions. Festo or third parties have 
protection rights concerning this electronic 
documentation which Festo makes available 

on portable data storage media (floppy disks, 

CD-Rom, removable disks) as well as on the 
Internet and/or Intranet - always referred 
to as electronic documentation hereinafter. 
Provided third parties are entitled to partial 
or full rights concerning this electronic 
documentation, Festo shall have the 
corresponding rights of use. Festo permits 
the user to use the electronic documentation 
under the following conditions:

1.  Scope of use

a) The user of the electronic documentation 
is allowed to use this documentation for his 
own, exclusively company-internal purposes 
on any number of machines within his 
business premises (location). This right of 
use includes exclusively the right to save 
the electronic documentation on the central 
processors (machines) used at the location.

b) The electronic documentation may be 
printed out on a printer at the location of 
the user as often as desired, providing this 
printout is printed with or kept in a safe place 
together with these conditions of use and 
other user instructions.

c) With the exception of the Festo logo, 
the user has the right to use pictures and 
texts from the electronic documentation 
for creating his own machine and system 
documentation. The use of the Festo logo 
requires written consent from Festo. The user 
himself is responsible for ensuring that the 
pictures and texts used match the machine/
system or the relevant product.

d) Further uses are permitted within the 
following framework:

Copying exclusively for use within the 
framework of machine and system 
documentation from electronic documents 
of all documented supplier components. 
Demonstrating to third parties exclusively 
under guarantee that no data material is 
stored wholly or partly in other networks 
or other data storage media or can be 
reproduced there.

Passing on printouts to third parties outside 
of the provision stated in item 3, as well as 
any editing or other use, is not permitted.

2.  Copyright note

Every “electronic document” receives 
a copyright note. This note must be included 
on every copy and every printout.

Example: E 2003, Festo AG & Co. KG, 
D-73726 Esslingen

3.  Transferring the authorisation  

of use

The user can transfer the authorisation of 
use in the scope of and with the limitations 
of the conditions in accordance with items 1 
and 2 completely to a third party. The third 
party must be made explicitly aware of these 
conditions of use.

II.  Exporting the electronic 

documentation

When exporting the electronic 
documentation, the licence holder 
must observe the export regulations of 
the exporting country and those of the 
purchasing country.

III. Warranty

1. Festo products are being further developed 
with regard to hardware and software. 
The hardware status and, where applicable, 
the software status of the product can be 
found on the type plate of the product. 
If the electronic documentation, no matter 
in what form, does not directly accompany 
the product, i. e. if the product is not supplied 
together with a portable data storage medium 

(floppy disk, CD-Rom, removable disk), 

Festo does not guarantee that the electronic 
documentation corresponds to every 
hardware and software status of the product. 
In this case, the printed documentation from 
Festo accompanying the product alone is 
decisive for ensuring that the hardware and 
software status of the product matches that 
of the electronic documentation.

2. The information contained in this electronic 
documentation can be amended by Festo 
without prior notice and does not commit 
Festo in any way.

IV.  Liability/Limitations of liability

1. Festo supplies this electronic 
documentation in order to assist the 
user in creating his machine and system 
documentation. In the case of electronic 
documentation that does not directly 
accompany a product in the form of portable 

data storage media (floppy disk, CD-Rom, 

removable disk), i. e. that is not supplied 
together with that product, Festo does not 
guarantee that the electronic documentation 

provided/supplied separately matches 
the product actually used by the user.

The latter applies particularly to extracts 
of the documents for the user’s own 
documentation. The guarantee and liability 
for separately provided/supplied data 
storage media, i. e. except for the electronic 
documentation provided/supplied via the 
Internet/Intranet, is limited exclusively to 
proper duplication of the software, whereby 
Festo guarantees that in each case the 
data storage medium or software contains 
the latest update of the documentation. 
Concerning electronic documentation 
available on the Internet/Intranet, there is no 
guarantee that it will have the same version 
status as the last typographically published 
edition.

2. Furthermore, Festo cannot be held liable 
for the lack of economic success or for 
damage or claims by third parties resulting 
from the use of the documentation by the 
user, with the exception of claims arising from 
infringement of the protection rights of third 
parties concerning the use of the electronic 
documentation.

3. The limitations of liability as per 
paragraphs 1 and 2 do not apply if, in cases 
of intent or gross negligence or the lack 
of warranted quality, liability is absolutely 
necessary. In such a case, Festo’s liability is 
limited to the damage discernable by Festo 

when the definitive circumstances are made 

known.

V.  Safety guidelines/documentation

Warranty and liability claims in conformity 
with the aforementioned regulations (items 
III. and IV) may be raised only if the user 
has observed the safety guidelines of the 
documentation in conjunction with the use 
of the machine and its safety guidelines. 
The user himself is responsible for ensuring 
that the electronic documentation, when 
not supplied with the product, matches 
the product actually used by the user.
