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 43 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 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.
For relationship between direction of rotation and flow direction,
see data sheet 92035.
