External hydraulic circuit controls
Controls of external hydraulic circuit description
FHD18N067
The controller (I) controls the quick couplings (1) and (2)
The controller (II) controls the quick couplings (3) and (4)
The controller (III) controls the quick couplings (5) and (6)
The controller (IV) controls the quick couplings (7) and (8)
The quick coupling (0) is directly connected to the distributor compartment and is intended for return oil from
external hydraulic appliances (especially rotary hydraulic motors).
If the tractor is fitted with front outlets (quick couplings) these are controlled by the controller (III) and the
quick couplings (5) and (6) are not assembled.
If the tractor is fitted with an additional front-circuit distributor, the front outlets and front three-point hitch are
controlled by a joystick and the rear quick couplings (5) and (6) are mounted.
External hydraulic circuit controls activation
1 . system activation button
2 . joystick activation or front outlets switch button
3 . joystick
4 . applicable hydraulic circuit controls
5 . system status controls
6 . pivoting selectors for setting the disengagement of
applicable hydraulic circuit depending on time
7 . pivoting selectors for setting the flow of oil of an
applicable hydraulic circuit
FHD18N065
External hydraulic circuit control gets activated with the
engine running by a longer press of a button ( 1 )
(approximately 3 seconds).
Control activation is signalized by a lit symbol on the
button.
Activated control can be deactivated by another press of
the button (
1 ); symbol on the button will go off.
When turning the engine off, the control is deactivated
automatically.
