1About this operating manual
This operating manual describes in detail the use, installation, assembly and
maintenance of a actuating cylinder FORTO-H. The efficiency of the actuat-
ing cylinder depends primarily on correct use and careful maintenance. This
operating manual serves as the leading document and is provided on deliv-
ery of the product. The personnel must have carefully read and understood
the operating manual before beginning any work. Observance of all safety
instructions and instructions for use in these operating manual is the basic
prerequisite for safe work with the actuating cylinder. In addition to the reg-
ulations listed here, local and user-related operating instructions and pro-
fessional accident prevention regulations are to be observed.

1.3 Liability and Warranty
All information and instructions in this operating manual are given in good
faith on the basis of our experience and knowledge to date. The products of
RÖHM are subject to constant further development. RÖHM therefore re-
serves the right to make any modifications and improvements deemed use-
ful. However, there is no obligation to extend these modifications and ex-
tensions to any previously delivered actuating cylinder. The actuating cylin-
der is constructed exclusively for the purpose specified under “Intended
Use”. Any use beyond this is deemed to be inappropriate. RÖHM is not li-
able for damage resulting from such use. The risk is borne solely by the op-
erator. Product liability for consequential damage of any type is excluded
for damage and operational interruptions resulting from operating errors,
failure to observe this operating manual or incorrect maintenance by unau-
thorised personnel.
RÖHM expressly points out that replacement and wear parts not supplied
by RÖHM must be authorised by RÖHM. RÖHM does not accept liability for
unauthorised replacement and wear parts. This applies to both product liab-
ility for consequential damage of all types and to liability for damage to
property.
All unauthorised conversions, modifications to the actuating cylinder and/or
changes in conditions are not permitted for safety reasons and exclude
RÖHM from any liability for any damage which may result. If modifications
to the actuating cylinder are necessary or the area of use differs from the in-
tended use, this must be agreed with the express permission of RÖHM.
The statutory and contractually agreed terms and conditions apply.
The following damage or defects are excluded from the warranty:
▪caused by the operator due to non-compliance with the written instruc-
tions of RÖHM with regard to
◦commissioning (e.g. incorrect construction and assembly work),
◦operation and
◦maintenance of the equipment (insofar as this maintenance has not been
contractually taken over by RÖHM).
▪caused by technical operating conditions unknown to RÖHM (e.g.
chemical or electrolytic influences) and/or machine specifications.
▪caused by natural wear.
▪caused by force majeure.
▪caused by incorrect operation of all types or by incorrect use or opera-
tion of the actuating cylinder. This also includes loading beyond the
specified load limits (e.g. speed, pressure, force, etc.).
This also includes damage caused

▪if the operator or third parties carry out modifications or repairs to the
services / products without prior permission of RÖHM. Excepted from
this are damage or defects which have occurred and which were
demonstrably not due to these modifications or repairs.
▪which occur due to use of the actuating cylinder under altered operating
conditions (e.g. materials, tools, cutting parameters, programs, etc.), in
particular without consulting and obtaining written authorisation from
the seller or RÖHM.
▪which are due to altered environmental conditions.
