Control lever has three positions:

Position "1" – supply of oil under pressure, control lever returns to neutral position automatically

Position "0" – neutral position

Position "1" – supply of oil under pressure, control lever returns to neutral position automatically
One-/two-way control valve
This valve is very similar to two-way functioning control valve, but in can be, with a special screw,
transformed into one-way functioning control valve.
Standard tractor version is fitted with two one-way functioning 5/3-directional control valves:

For control of rear hydraulic lift mechanism

For control of implements with one-way functioning hydraulic cylinder
And one two-way functioning 6/3-directional control valve:

For control of implements with two-way functioning hydraulic cylinder.
CONTROL ELEMENT (THREE CONTROL LEVERS)
Below is a description of distribution of functions according to control levers.
CONTROL OF REAR HYDRAULIC LIFT MECHANISM (SINGLE)
Control lever A
Control lever redirects oil from pressure circuit through
one-way functioning directional control valve, directly to
both
one-way functioning hydraulic cylinders
simultaneously, to control rear hydraulic lift mechanism.
Operation:

If you move the lever up to position 1, lift
mechanism rises. When you release it, the lever
on the control element automatically returns to
neutral position 0, and the lift mechanism remains
in this lift position.

If you move the lever down to position 2, lift
mechanism starts to lower. Even when you
release it, the lever remains fixed in position 2.
Therefore, you must always manually move it to
position 0, if you want to cancel lowering of lift
mechanism.
When the control lever is in position 2, and the lift mechanism is completely lowered, implement shifts to
float position, so that it can adapt to the ground.
IMPORTANT: If the control valves are not being used, control levers must
always be set to neutral position.
