PARK PRO 540 IX - 740 IOX

4.5.2 Functional description

Auxiliary hydraulics not in use
Operation state:
• Motor is running in full speed.
• The steering wheel is not actuated.
• The implement lifter is not activated.
The hydraulic pump (A) is forcing oil through the steering valve (B), and the opened valves
(Aux2, Aux1 and L).
The oil flow is indicated with arrows in the figure below. Since neither of the items are work-
ing, the resistance can be ignored and the pressure is very low (<1 bar).
In the normal condition, the lifting cylinder (L1) is locked in its set position, because no oil
can flow out or in since the oil lines are shut by the slide.
