In addition to the ports specified in Table 10 "Ports A36VM" on page 35,
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 37 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.
