Two-way operation of hydraulic cylinder , the pressure from hydraulic oil acts on the
piston in the cylinder alternately from both sides (depending on the position of the
control lever), which allows the cylinder to be moved in both directions.

The hydraulic lift mechanism function is no longer attributed to the control lever A, but is moved
to the control lever C of the control device; see chapter “Hydraulic controls”.
Control lever C (see Fig. 71) directs the oil
from the pressure circuit, which is directly
supplied to both double-acting hydraulic
cylinders at the same time, by means of a
control valve in the control device, to control
the rear hydraulic lift mechanism.
The rotary button is used to dampen the
lowering, see chapter “The rear hydraulic lift
mechanism control”.
The control lever has four positions:
•
“Position 0”, neutral position of the lever, the lift mechanism remains in position.
•
“Position 1”, the oil under pressure is supplied, the rear hydraulic mechanism is raised.
When the lever on the control device is released, it remains blocked inside its guide in
position 1, which is why it must always be manually moved to position 0 in order to stop
the lifting movement.
•
“Position 2”, the oil is discharged, the rear hydraulic mechanism is lowered. As the lever
is blocked inside its guide, it will remain in position 2, which is why it must always be
manually moved to position 0 in order to stop the lowering movement.
•
“Position 3”, the oil is releases, the rear hydraulic lift mechanism starts to lower, the lever
remains fixed in position 3 and must always be manually moved to position 0.
