3. Use of the product
Transport
Depending on size, lifting equipment or transport
aids are needed. Our product leaves the factory in
perfect working order, and appropriate packaging
is used to protect it from damage.
The condition of the product on arrival is no
longer under our control, so please check for
transport damage/defects immediately after
arrival. Document the transport damage and
immediately notify the carrier, the insurance
company and the manufacturer. Do not dis-
pose of the packaging unless there is no trans-
port damage and the entire package contents
have been removed from the packaging. If
the product has been damaged during trans-
port, it must be exchanged for a new one.
When transporting the product within your premis-
es, make sure it is kept in a safe position and pro-
tected in its original packaging until it is ready to
use. Note also the information in sections “Warranty
and liability”, “Basic information on using the man-
ual”, "Other applicable standards/rules", “Person-
nel requirements”, “Remaining risks”.
Storage
If the product needs to be temporarily stored, it
must be protected from dirt, the weather, and dam-
age. Each valve is tested with hydraulic oil in the
factory, so that the internal components are pro-
tected from corrosion. However, this protection can
only be guaranteed under the following conditions:
The product is delivered with adequate corrosion
protection, provided our recommendations for the
ambient conditions are followed.
Storage outside or in maritime or tropical cli-
mates without appropriate packaging leads
to corrosion and may make the product un-
usable.
Make sure the product is stored so that no
injuries can be caused by tipping or falling. In
particular, make sure that the safety rules for
high-bay racking are followed.
Commissioning
After installing our product in a system/machine,
make sure that the requirements of the Machinery
Directive are met if applicable. Access should be
provided to the hydraulic diagram, the equipment
list and the logic diagram for the system/machine.
The product must be checked for damage
and missing parts (e.g. seals) before instal-
lation, especially in the area of the sealing
surfaces and the safety devices. If the safe-
ty devices or sealing surfaces are damaged
or are missing individual parts with relevance
to the product's function, the product may not
be used.
Remove all transport securing devices, protective
covers and packaging.
Check for foreign objects in the open hydrau-
lic passages. Contaminations may impair op-
erational reliability and shorten the service
life.
Make sure that the hydraulic system/machine
is unpressurised before the product is in-
stalled.
Before commissioning, the specialist person-
nel must verify that the entire hydraulic sys-
tem has been installed correctly. Commis-
sioning must be carried out with care, taking
account of all safety regulations.
If necessary, erect warning signs to prevent unin-
tended operation. Note also the information in sec-
tions “Warranty and liability”, “Basic information on
using the manual”, "Other applicable standards/
rules", “Personnel requirements”, “Remaining risks”.
Compare valve type (located on the name plate)
with part list resp. circuit diagram.
