Replacing O rings: The mounting surface O rings may be re-
placed by the customer (on the pilot valves and the way valves
as well). The O rings of the pilot valve and the way valve of the
D941 must not be replaced by the customer. Pay attention to
cleanliness of the valve and of the surroundings.
Transportation/storage: Before transportation, seal the base
of the valve using a clean shipping plate or adhesive tape.
Seal the connector using a dust protection cap. Pack the valve
carefully so that it is not damaged during transportation or stor-
age.
Inspection: Following a period of storage or no operation for
more than 5 years, we recommend that the valve is inspected
by an authorized service center, in order to prevent possible
damage.
Repairs: Repairs may only be carried out by us or by our au-
thorized service centers.
Repaired valves or replacement valves are delivered like
new valves with factory settings. Therefore, the valves have
to be checked for correct configuration and changed parame-
terization before re-initiation. If necessary, the user has to re-
store the machine manufacturer's original configuration and
parameterization.
10 Disposal
It is essential to comply with the relevant national waste dis-
posal regulations and environmental protection provisions
when disposing of valves, spare parts or accessories, packag-
ing that is no longer needed, hydraulic fluid or auxiliary materi-
als and substances used for cleaning!
