, A2FM/A2FE/A2FMT Series 70, RE 91071-01-B/06.2018
To connect the axial piston unit to the hydraulic system:
1.
Remove the protective plugs or threaded plugs from the ports where the
connections should be made according to the hydraulic circuit diagram.
2.
Make sure that 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 38 when you flush out the entire system.)
4.
Connect the lines in accordance with the installation drawing and the machine or
system circuit diagram. Check whether all ports are connected or plugged with
threaded plugs.
5.
Tighten the fittings correctly (note tightening torques!). Mark all correctly
tightened fittings, e.g. with a permanent 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:
A to B
Counter-clockwise rotation: B to A
7.5 Performing flushing cycle
In order to remove foreign particles from the system, Bosch Rexroth recommends
a flushing cycle for the entire system before initial 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.
