Conditions of use for “electronic documentation”

I.  Protection rights and scope  

of use

The file of your choice is subject to protec-
tion provisions. Festo or third parties have 
protection rights concerning this electronic 
documentation which Festo makes available 
on portable data storage devices (floppy 
disks, CD-ROM, removable disks) as well as 
on the Internet and/or Intranet, hereinafter 
referred to as electronic documentation. 
Provided third parties are entitled to partial 
or full rights concerning this electronic docu-
mentation, Festo shall have the correspond-
ing 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 documenta-
tion 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 creat-
ing his own machine and system documen-
tation. 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 fol-
lowing framework:

Copying exclusively for use within the frame-
work 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 devices 
or can be reproduced there.

Passing on printouts to third parties not 
covered by the provision stated in item 3, as 
well as any processing 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 documenta-
tion, 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 continuously 
developed with regard to hardware and soft-
ware. The hardware status and, where appli-
cable, the software status of the product can 
be found on the name plate of the product. 
If the electronic documentation, in whatever 
form, is not supplied with the product, i. e. 
is not supplied on a portable data storage 
device (floppy disk, CD-ROM, removable 
disk), Festo does not guarantee that the elec-
tronic 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 documenta-
tion 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 devices (floppy disk, 
CD-ROM, removable disk), i. e. that is not 
automatically supplied together with that 
product, Festo does not guarantee that the 
electronic documentation available/supplied 
separately matches the product actually used 
by the user.

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

2. Furthermore, Festo cannot be held liable 
for the lack of economic success or for dam-
age 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 para-
graphs 1 and 2 do not apply if, in cases of 
intent or gross negligence or the lack of 
warranted quality, liability is compulsory. In 
such a case, Festo’s liability is limited to the 
damage discernable by Festo when the defini-
tive 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 docu-
mentation 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 actu-
ally used by the user.
