36/52 A2FO series 70 | Installation
To connect the axial piston unit to the hydraulic system:
1� Remove the protective plugs and/or threaded plugs from the ports where the
connections should be made according to the hydraulic circuit diagram.
2� Make sure the sealing surfaces of the hydraulic ports and functional surfaces are
not damaged.
3� Use only clean hydraulic lines or flush them before installation.
(Observe chapter 7.5 "Performing flushing cycle" on page 36 when you flush
the hydraulic system.)
4� Connect the lines in accordance with the installation drawing and the machine
or system circuit diagram. Check that all ports are connected or plugged with
threaded plugs.
5� Properly tighten the fittings (observe tightening torques!). Mark all properly
tightened fittings, e.g.with apermanent marker.
6� Check all pipes and hose lines and every combination of connecting pieces,
couplings or connecting points with hoses or pipes to ensure they are in safe
working condition.
Relationship between direction of rotation and flow direction:
Clockwise rotation: S to B
Counter-clockwise rotation: S to A
7�5 Performing flushing cycle
In order to remove foreign particles from the system, BoschRexroth recommends
a flushing cycle for the hydraulic system before the first commissioning. To avoid
internal contamination, do not include the axial piston unit in the flushing cycle.
Use an additional flushing unit to perform the flushing cycle. Follow the
instructions of the flushing unit's manufacturer for the exact procedure during
the flushing cycle.
