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
transport damage and the entire package
contents have been removed from the pack-
aging. If the product has been damaged
during transport, it must be exchanged for a
new one.
When transporting the product within your premises,
make sure it is kept in a safe position and protected
in its original packaging until it is ready to use. Note
also the information in sections “Warranty and li-
ability”, “Basic information on using the manual”,
"Other applicable standards/rules", “Personnel
requirements”, “Remaining risks”.
Storage
If the product needs to be temporarily stored, it must
be protected from dirt, the weather, and damage.
Each valve is tested with hydraulic oil in the factory,
so that the internal components are protected 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
climates without appropriate packaging leads
to corrosion and may make the product unus-
able.
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 safety
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
operational 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 system
has been installed correctly. Commissioning
must be carried out with care, taking account
of all safety regulations.
If necessary, erect warning signs to prevent un-
intended operation. Note also the information in
sections “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.
