1)
The tightening torques for the threaded plugs are valid for the condition "dry" and "lightly oiled".
2)
The tightening torques for the threaded plugs are valid for the condition "dry" – inthe condition "lightly oiled", the tightening torques
for M10×1 are reduced to10Nm and for M12×1.5 to17Nm.
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 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42 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 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.
