1)    Attention! The applied pressure adds to the set pressure! The switching pressure differential remains unchanged within the setting range!
2)    (after switching P to T)
3)    (after switching A to T)
4)    The cleanliness classes specified for the components must be adhered to in hydraulic systems. Effective filtration prevents faults and simultaneously increases the life cycle of the components. For the selection of the filters, see www.boschrexroth.com/filter.
