4.5.2 Functional description

Normal condition

Operation state:

• Motor is running in full speed.
• The steering wheel is not actuated.
• The implement lifter is not activated.
The loading pump (1) is forcing oil through the steering converter (5), and the open valve
(9).
The oil flow is indicated with arrows in the figure below. Since neither of the two items are
working, the resistance can be ignored and the pressure is very low (<1 bar).
In the normal condition, the lifting cylinder (11) is locked in its set position, because no oil
can flow out or in since the oil lines are shut by the slide (9).
