In addition to the ports specified in Table 8 "Ports A10VOH145 series 60"
on page 37, axial piston units may have openings that are also closed with
a threaded plug. These plugs must not be opened on the customer side.
If you have opened the threaded plug accidentally, please contact your local
contact person to ensure safe re-closing of the plug. You can find the address at

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 40 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. For inside-reservoir installation, the housing of the
axial piston unit must be filled before fitting the lines and filling the reservoir
with hydraulic fluid.
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.
