Outer Hydraulic Circuit Controls; Locking Control Levers - Zetor PROXIMA GP Series Operator's Manual

Outer hydraulic circuit controls

The control levers of the outer hydraulic circuit are distinguished by colours. The lever colour corresponds to
the colour of quick coupler dusters that are controlled by the corresponding lever.
Outer hydraulic circuit controls are located on the right wing.
lever (a) controls the lower section of distributor - quick couplers (1) and (2)
lever (b) controls the central section of distributor - quick couplers (3) and (4)
lever (c) controls the upper section of distributor - quick couplers (5) and (6)
Quick coupler (0) is directly connected with transmission and it is supposed for recuperative oil of exterior
hydraulic appliances (e.g. from rotary hydraulic engines etc.).
According to the equipment of the tractor, the following combinations of control levers and quick couplers can
be supplied:
lever (a) - quick couplers (1) and (2)
levers (a) and (b) - quick couplers (1), (2), (3) and (4)
levers (a),(b) and (c) - quick couplers (1), (2), (3), (4), (5) and (6)
Quick coupler (0) is supplied in any case.
If the tractor is equipped with front three-point hitch, use lever (b) to control it. When the front
three-point hitch is used, quick couplers cannot be connected as they are pressured together with
the front three-point hitch! When you finish using the front three-point hitch and want to use the
section with quick couplers 3 and 4 with connection to the front three-point hitch, raise the arms of
the front three-point hitch to the transport position and move the front three-point hitch lever to the
'locked' position.

Locking control levers

Outer hydraulic circuit control levers are locked in neutral
(N) position.
To unlock them, raise the lock control (1) and turn it to
a stop point in the direction shown by the arrow.
To lock them again, move the levers to neutral (N) position
and turn the lock control in the opposite direction than
shown by the arrow to a stop point and push the control
down. This locks the lever in neutral position.
For safety reasons, always lock outer hydraulic
circuit levers in neutral position (N).
