Description of the functions of individual positions of control levers of the hydraulic distributor
FH12N049
Always connect a single-acting cylinder to quick couplers:
1, 3, 5 of the three-section auxiliary distributor.
Always connect a double-acting cylinder to quick-couplers of one section.
Rear outlets of the outer hydraulic circuit
In the tractors equipped with front outlets, the quick couplers 5 and 6 are not mounted on the
rear panel.
Lever position

Rear (upper)
position
Pressurized oil flows to quick-couplers:
1, 3, 5
Quick-couplers connected to the return line:
2, 4, 6

Front (lower)
position
Pressurized oil flows to quick-couplers:

Front limit position
With an increased force you can shift the control levers from position (3) further
to the front to position (4), i.e. floating (free) position, where the levers are
locked. Both the quick-couplers of each section are connected to the return line
in this position.
In a tractor version that is not equipped with front outlets
or a front three-point hitch, the rear outlets are terminated
by pressure quick couplings 1 to 6.
The quick coupling marked 0 is directly connected to the
transmission compartment and is intended for return oil
from external hydraulic appliances (especially rotating
hydro engines).
