In addition to the ports specified in Table 11 "Ports A10VOH series 60" on
page 38, 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 41 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. With 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.
