The tightening torques of the M
V
threaded plugs apply for the screws in the “dry” state received on delivery and for the “lightly oiled”
state for installation.
2)
In the “lightly oiled” state, M
V
is reduced to 10 Nm or M10 x 1 to 17 Nm for M12 x 1.5. For the delivery condition “dry” and for
reduced M
V
, 10Nm for M10x1 and 17Nm for M12x1.5, the maximum permissible pressure is 420bar.
To connect the axial piston unit to the hydraulic system:
1. Remove the protective plugs and threaded plugs at the ports at which the
connections are to be made according to the hydraulic circuit diagram.
2. Make certain that the sealing surfaces of the hydraulic ports and functional
surfaces are not damaged.
3. Use only clean hydraulic lines or flush them before installation. (Note chapter7.5
“Performing flushing cycle” on page 40 when you flush out the complete
system.)
4. Connect the lines in accordance with the installation drawing and the machine or
system circuit diagram. Check whether all ports are connected or plugged with
threaded plugs.
5. Tighten the fittings correctly (note tightening torques). Mark all correctly
tightened fittings, e.g. with a permanent marker.
