5.3 Operating instructions
Product, pressure and/or flow settings
All statements in this documentation must be observed for all product, pressure and/or flow settings on or in the hydraulic system.
Filtering and purity of the hydraulic fluid
Soiling in the fine range, e.g. abraded material and dust, or in the macro range, e.g. chips, rubber particles from hoses and seals, can
cause significant malfunctions in a hydraulic system. It is also to be noted that new hydraulic fluid “from the drum” does not necessari-
ly meet the highest purity requirements.
Pay attention to the purity of the hydraulic fluid in order to maintain faultless operation (also see cleanliness level in Chapter 3,
"Parameters").
5.4 Maintenance information
This product is largely maintenance-free.
Conduct a visual inspection to check the hydraulic connections for damage at regular intervals, but at least once per year. If external
leaks are found, shut down and remedy.
Check the device surfaces for dust deposits at regular intervals (but at least annually) and clean the device if required.

Other information
6.1 Planning information
If using with classes of consumers in which pressure and oil flow surges (decompression) may occur in direction F d B due to
the storage effect combined with fast-switching directional valves, throttling points (e.g. in line with small inflow bores) must be
implemented and designed in such a way that a volumetric flow no greater than that permitted is reached during the pressure difference
at the start of decompression.
