Cleaning and care
Penetrating dirt and liquids will cause faults!
Safe function of the valve is no longer ensured.
Always provide for absolute cleanness when working on the valve.
Do not use a pressure washer.
Damage to the surface from solvents and aggressive cleaning agents!
Aggressive detergents may damage the seals and the surface of the valve and let
them age faster.
Never use solvents or aggressive detergents.
Do not use pressure washers for cleaning.
Damage to the hydraulic system and seals!
A pressure washer's water pressure could damage the hydraulic system and
the seals of the valve. The water displaces the oil from the hydraulic system
and seals.
Do not use pressure washers for cleaning.
Cover all openings with appropriate protective caps.
Check that all seals and plugs for the plug-in connections are firmly fitted so
that no humidity can penetrate the valve during cleaning.
Only clean the valve using a damp, lint-free cloth. Only use water and a mild
cleaning agent, if necessary, to do so.
Flush the hydraulic system if necessary. Replace the fluid filter or the hydrau-
lic medium.
9.3
Inspection and maintenance
Dust accumulations on the valve have to be removed at regular intervals.
The following inspection, testing and maintenance works are to be carried out
regularly. Also considering the operating conditions, the corresponding intervals
are to be chosen so that defects that can reasonably be expected are dealt with
in good time. However, the inspection has to be implemented at least every three
years counting from the manufacturing date of the valve. The manufacturing date
of the valve can be found on the name plate, see section "4.3 Product identifica-
tion" on page 12.
The inspection must also be carried out if the valve is only stored but not used!
Ordering details for seal kits can be found in section
"9.5 Spare parts" on page 32.
Have sufficiently dimensioned collection containers, enough clean-
ing cloths and medium-binding materials ready in order to collect or bind
leaking medium.
